Pulselio: AI Health Tracker · Leading Software Development Studio

# 74k installs, 38 ratings: Pulselio "face heart-rate scanner" runs on a reskinned template and one ad push

**What it is** A health app that reads heart rate, breathing, HRV, stress and skin age from your face, uses AI to write a health summary, and charges weekly, monthly or yearly subscriptions, with ads for users who don't pay.

**Why it took off** The same publisher moved its antiques, coin and tattoo identification template into health. About 56k installs were bought in October (cheap countries for volume, Australia and the US for subscriptions), plus a "does not measure blood pressure" line that helps it pass review and keep running ads.

**C** **How you could follow it** Don't build another heart-rate app. Teams with a ready template and paid acquisition can copy the skeleton: find a "snap and get a result" category that isn't crowded yet, state clearly in health apps what they don't measure, and split by region, buying cheap installs to climb the charts and collecting subscriptions in the higher-paying countries.

C: there are tens-of-millions-install rivals, big portfolio publishers like iKame, and Google Fit gives the same feature for free. Even after a full round of spend, Pulselio only reached #50 on the Australia Top Grossing chart with poor reviews. What's worth learning is the reskin + compliant copy + paid acquisition playbook, but copying it now isn't worth it. Almost nobody knows about it yet

Android · Ratings count (cumulative)

Data 2026-10-29 → 2026-11-07 (10 days, 10 observations)

In 2026 Sep 30, a user named Chelsea Reed left a review on Google Play for an app that had been live for a month: "The height and weight page won't get past." That day the app had about 3 thousand installs. A week later, another one-star review got 6 "helpful" votes: "Completely inaccurate, and you have to pay for fake results." The app is Pulselio: AI Health Tracker. It looks at your face through the front camera and reports heart rate, breathing, HRV, stress, and "skin age." By Nov 6, it had 74,544 installs but only 38 ratings, and it ranked #50 on the Australia Health & Fitness Top Grossing chart. Below: who made it, how the numbers were built, where the money comes from, and why you probably shouldn't copy it.

### What it is

A subscription "measure your health with the camera" app. The store listing pitches rPPG, which estimates pulse from tiny changes in skin color in a face video, a technique that has existed for over a decade. After a scan, it uses Gemini to generate an "AI health risk summary" and daily advice, plus manually entered body metrics like BMI and waist-to-height ratio, with trend charts.

Paid through weekly, monthly, and yearly auto-renewing plans. The in-app purchase range on Google Play is listed as $9.99–$39.99. Free users see interstitial, banner, and rewarded ads (the subscription terms say members get "no interstitial, banner, or rewarded ads").

The store listing prominently states: "Pulselio does not scan or measure blood pressure, blood sugar, or blood oxygen" and "is not a medical device." Many similar apps claim to measure blood pressure; this one explicitly says it doesn't. More on that line below.

### Who made it: the Nth package in a reskin matrix

The Play developer is listed as "Leading Software Development Studio," the legal entity is SkySynth Technology Inc, the address is in Colorado, USA, but the contact number is a Malaysian +60 number. The iOS seller for the same product is Shenzhen Yunduoduo Technology Co., Ltd, which listed it in 2026 Sep 13, and it has only 2 ratings on the US App Store.

Open this developer's "More apps" and the template is obvious: AI tattoo design (171k installs on Play, from 2024), AI car modification, AI calorie counter, AntiqWise antique appraisal, Coinlyzer coin identification, Cardlio card valuation... 13 apps under the same iOS account. They're all "snap or scan → AI gives a result → paywall," one skeleton in many skins. Pulselio is the skin put on the health category.

The cost-cutting shows in the details: the support email in the subscription terms is Multilanguage-Translator@outlook.com, clearly copied from a translation app. The app name in the terms is written "AI Health Trackr," missing an e. The website and privacy policy sit on a free vercel.app subdomain. The listing says "privacy first, your face is not saved," yet the data safety section on the same page says "data not encrypted" and "data cannot be deleted."

The same account also published a near-identical twin, Vimetra: Health Tracker & Scan, with the same features and the same vercel website. 11-06 its US store page shows 1K+ downloads. If one package gets banned or doesn't pay back, switch to the other. That's standard matrix insurance.

### The volume was bought, and the curve shows it

Plotting Pulselio's cumulative installs by date (late September to October are third-party estimates; from 10-29 onward are public Google Play figures):

| Date | Total installs | What happened |
|---|---|---|
| 08-31 | — | Launched |
| 09-30 | About 3k |  |
| 10-04 | About 7k | One jump of about 3.6 thousand |
| 10-08 | About 14k | Another jump of about 6.6 thousand |
| 10-13 | About 32k | About 18k added in 5 days |
| 10-21 | About 60k |  |
| 10-29 ~ 10-31 | 65,803 | Three days with no growth at all |
| 11-01 / 11-03 | 69,354 / 73,311 | Each jump about 3.5–4 thousand |
| 11-06 | 74,544 | 7 days +8,741 |

Organic growth is a smooth upward line. This one is a staircase: from Oct 4 to 21 roughly 56k was released, then it stalled for three days at the end of the month, and two more small batches came in early November. On the reputation side: 74.5k installs, 38 ratings, a ratio of about 0.05%. The rating distribution is 19 one-star, 5 four-star, 13 five-star, with no two- or three-star. Searching "pulselio" on TikTok, X, and Reddit returns nothing, and no media outlet has written about it.

So it wasn't pushed by word of mouth; it was bought. I couldn't trace where: Google's Ads Transparency Center returns nothing for the company name, product name, or domain, and Meta's Ad Library has no page for it. Most likely it ran on programmatic ad networks like AppLovin, Mintegral, or Unity, or used other advertiser names as cover.

### Where the money comes from: cheap countries buy volume, expensive countries pay

It has reached #59–95 on the Mexico Health & Fitness Top Free chart. Third-party data claims about 40% of its traffic is from Mexico, with one to two tens of percent each from Venezuela and Colombia (unverified). The username on the one-star review complaining about constant crashes looks East African. Traffic from these places is cheap; it inflates install counts and category rank, and free users who watch ads recover a little revenue.

The paying users are on the other end: it ranks #11-06 50 on the Australia Health & Fitness Top Grossing chart (10-29 was #59, so it's rising), and sits between #105 and #127 in the US. Meanwhile it keeps sliding on the free charts in each country: Australia dropped from #111 to #194, and in the US it fell out of the top 11-02 after 200. New installs are declining while Top Grossing rank holds steady, which suggests some of the people bought in October are renewing weekly or monthly.

A #50 ranking on Australia's Health & Fitness Top Grossing chart is roughly tens to a hundred-plus dollars per day in revenue, unverified. For a reskin with near-zero marginal cost, that's enough to keep it alive. For someone starting from scratch, it isn't much.

### Who it's competing with

Camera-based heart rate measurement has been a stock playbook since 2012, and this category is already a crowd of matrix publishers copying each other:

| Competitors | Scale (Google Play, 11-06) | How Pulselio differs |
|---|---|---|
| Google Fit has built-in heart rate / breathing measurement | 370M installs | Free, same thing |
| Heart Rate Monitor - HeartIn | 9.12M installs, #18 Top Grossing in Australia, #26 in the US | Finger-on-flashlight measurement, 120 times its scale, and proven to make money |
| Welltory | 5.99M installs, #47 Top Grossing in the US | Veteran HRV / stress app, mainly reads watch data |
| CardioLens | 1.75M installs, +76k in 7 days | Finger-based, claims to show blood pressure too; one week's increase equals Pulselio's total |
| iCardiac(iKame) | 1.59M installs, #51 Top Grossing in Australia | Large publisher matrix; its Australian Top Grossing rank sits right next to this one |
| FaceVital(iKame) | 143k installs | Also face-based, markets "blood pressure trends" |
| Shen.AI's app | 465k installs | The company behind the rPPG technology has its own app, with clinical backing |
| Anura(NuraLogix) | — | Has been doing "30-second selfie health checks" since 2021, sold to insurers and telehealth |

Pulselio doesn't make this table. The only thing it can claim is one thing: face-based measurement, plus explicitly saying it doesn't measure blood pressure.

### How much the "doesn't measure blood pressure" line is worth

Face-based measurement feels more "AI" than finger-based, and the ad creatives are easy to shoot: one face with a few numbers floating over it. But FaceVital, Shen.AI, and Anura were already doing this, so it isn't unique.

What's actually useful is the compliance framing. Google Play's health policy and ad review are strictest about claims like "measure blood pressure, blood sugar, or blood oxygen with your phone camera." Pulselio sells only the few metrics rPPG can genuinely estimate (heart rate, breathing, HRV, stress) and writes out what it can't measure. For a package that lives on paid acquisition, that means less risk of delisting and fewer rejected ads. It's the condition that lets it keep spending, not the reason users come.

User feedback is negative: inaccurate, costs money, stuck on the data-entry page, crashes. The product exists because of the publisher's template and ad budget, not because of the product itself.

### If it were you

**Verdict** : C. You can learn a playbook of "reskin + paid acquisition + compliant copy," but copying a camera heart-rate app isn't worth it now: the category has tens-of-millions-install rivals and big matrix publishers like iKame, Google Fit gives the same feature away free, and even Pulselio after a full spend round only reached #50 in Australia's Top Grossing.

**Who it suits** : small teams that already have a "camera / photo → AI result → subscription" codebase, are running programmatic paid acquisition, and can calculate payback periods per country. For you, it's just one more SKU, with almost zero marginal cost.

**Who it doesn't suit** : indie devs hoping to build word of mouth (users here don't trust it, reviews are bad, organic installs are close to zero); anyone who can't run paid ads (this kind of app gets tens of installs a day without paid acquisition); anyone wanting to build a "measure blood pressure" app (it won't pass review or ad approval).

**How to do it** : if you build in this space, don't make "yet another heart-rate checker," but learn its skeleton. Take the same template to a "snap and get a result" category not yet crowded by matrices. Follow its health-app writing: only claim metrics the tech can really estimate, and state on the first screen of the listing what it doesn't measure and that it isn't a medical device. Offer weekly / monthly / yearly subscription tiers, with ads for free users. Run two packages per category and test by region.

**How to acquire users** : programmatic ad networks and Google App Ads. Cheap-country traffic pushes category charts; Australia, US, and Canada traffic pays for subscriptions. Don't count on TikTok or community spread; Pulselio has none of either.

**When to move** : the window for health apps isn't set by hype but by platform policy. Google Play tightens health policy every round, and the ones that survive are the conservative-claim ones. Read the latest health app policy before you start.

**What would mean you've misread it** : (1) before December, Pulselio reaches top 30 on the Australia or US Health & Fitness Top Grossing chart with no new install step-ups, meaning its subscriptions aren't propped up by ads and real users are sticking around; (2) its twin Vimetra climbs from 1K+ to over 100k within a month, meaning the operator is doubling down and this category pays back better than it looks; (3) conversely, if Pulselio stops spending after November and its Top Grossing rank drops out of the top 100, or it gets delisted, then even conservative claims plus matrix costs can't sustain it, and this category is one to stay away from.

Where users come from

- Inferred **Paid acquisition (channel unknown)** : installs jump in 10-04/10-08/10-13/10-21 steps; install rating ratio only 0.05%; Google Ads Transparency Center shows no_ads, no Meta Page in the library, likely bought on programmatic networks or under another advertiser name

- Inferred **Cheap-market volume + high-value market monetization** : reached #59–95 on the MX Top Free chart (recall card cites MX 39%/VE 22%/CO 12%, unverified); paid signals at #50 Top Grossing in AU and #116 in US

- **Verified** **Ad monetization subsidy** : subscription terms say members can remove interstitial, banner and rewarded ads

- **Verified** **Twin-package split test** : the same account also published Vimetra with the same features, the same vercel landing page, and a Facebook Page

- Inferred **Social/influencers/press** : TikHub, x-radar and Jina search all returned 0

## Pulselio: AI Health Tracker (com.pulselio.android.com): why it took off

### Verdict

Pulselio is a new SKU from a Chinese tool-matrix publisher. The iOS seller is "Shenzhen Yunduoduo Technology Co., Ltd"; the Play developer is "Leading Software Development Studio," with the legal entity registered as SKySynth Technology Inc (Colorado, US address, Malaysian +60 phone number). The product is "front-camera rPPG face-scan heart rate / breathing / HRV / stress / skin age," plus manual logging like BMI, monetized through $9.99–$39.99 weekly / monthly / yearly subscriptions, with interstitial, banner and rewarded ads on top.

- **Why it took off** : not product word of mouth. 74.5k installs produced only 38 ratings (about 0.05%), with a 1–5 star split of [19, 0, 0, 5, 13], piled at both ends with nothing in the middle. Reviews complain "inaccurate, you pay for results," "stuck on the height and weight page," "keeps crashing." Social platforms and media show no coverage of it at all. Its install curve steps up in October (10-04, 10-08, 10-13, 10-21), the shape of scaled paid buying. Our read is "paid acquisition + cheap-market volume + high-value-market subscriptions," but we couldn't find the specific channel in the Google Ads Transparency Center or our Meta library (see below).

- **Where the money comes from** : AU Health & Fitness Top Grossing has held steady at #49–59, and US at #105–127. These are real paid signals. Top Grossing ranks in the other 13 countries are all clustered at #149–170 and nearly identical, which is the artifact of a shared aggregate chart and shouldn't be trusted.

- **Differentiation** : some, but not why it took off. Unlike the mainstream "finger on flash for heart rate / claims blood pressure" apps in the category, it takes the compliant line of "face scan + explicitly no blood pressure, glucose or SpO2." That helps it clear Google Play health policy and ad review, a useful shield for paid acquisition. But Anura, Shen.AI and FaceVital have been doing face scanning for a while, and Google Fit already ships camera-based heart rate / breathing.

- **Visibility** : almost no one knows about it. No press coverage, no public revenue, 0 posts on X and TikTok.

### 1. Data

#### Google Play (googleplay library; before 10-29, AppstoreSpy estimates)

| Date | Total installs | Notes |
|---|---|---|
| 2026-08-31 | — | Store launch |
| 09-29 / 09-30 | 2,201 / 2,958 | AppstoreSpy started tracking |
| 10-04 | 7,008 | One jump of about 3.6k |
| 10-08 | 13,697 | Another jump of about 6.6k |
| 10-13 | 32,076 | About 16k added in 3 days |
| 10-21 | 59,550 | About 9.5k per day (averaged across observation intervals) |
| 10-27 | 65,800 | Reached a plateau, about 1k per day |
| 10-29 ~ 10-31 | 65,803 | Almost no growth for three days |
| 11-01 / 11-03 | 69,354 / 73,311 | Two more small pushes |
| 11-06 | 74,544 | 7 days +8,741 |

- Volume concentrated between Oct 4 and 21 (about 56k). Installs largely stopped at the end of October, with only a small continued push in early November. The curve is stepped, not the smooth rise of organic growth.

- Charts (chart_rank):
    - AU Health & Fitness Top Grossing: 10-29 at #59 → 11-05 at #49 → 11-06 at #50, steady with slight gains.
    - US Health & Fitness Top Grossing: between #105 and #127.
    - Top Free is slipping: MX fell from #59 to #95, then recovered to #77; AU fell from #111 to #194; after 11-02 it dropped out of the US top 200; SG and CA also dropped off.
    - Top Free (new installs from paid buying) is falling while Top Grossing (subscription renewals) holds, meaning some users bought in the previous wave are still paying.

- Only 38 ratings, averaging 2.86, distributed [19, 0, 0, 5, 13]. The 5-star ratings may be incentivized or self-sourced; the 1-star ratings are from users put off by the paywall. Version 1.0.6,10-20 has been updated.

- Reviews visible on the store page include: "garbage… not accurate… they want money to give you false results" (10-06,6 people found it helpful), "Doesn't let you get past the screen where you pick your height and weight" (09-30), "the app keeps on closing" (10-08, the username looks African).

- The recall card gives the traffic mix as MX 39%, VE 22%, CO 12% (source not stated; we can't verify it; VE and CO are not among the 30 storefronts we track). What we can see is that it did hit #59–95 on the MX Top Free chart, which fits the "buy cheap volume in Latin America" story.

#### iOS (iTunes lookup + appstore library)

- id 6806175301, seller Shenzhen Yunduoduo Technology Co., Ltd, listed 2026-09-13. The US store has only 2 ratings.

- It has only shown up on very low-bar charts in small storefronts like Angola (Top Grossing #9), Bolivia (#86), Qatar (#97), Egypt (#102), Jamaica, Kuwait and Oman. It barely ran on iOS; the main battlefield is Android.

#### Sister matrix (iTunes artistId 1689003189 + Play developer page)

- Under the same iOS account, 13 apps: Ai Tattoo Ideas (3,819 rating, 2024), Car Editor & AI Car Designer (1,857), Dream Space AI home design, AI Calorie Counter: Panda Cal, AntiqWise antique appraisal (2026-06), Cardlio card valuation (2026-09), Translate Hub (2026-10-31), Minute Transcribe and more. The appstore library also shows the same seller launching a short-term stock picker in the China store.

- Same Play account: Ai Tattoo (171k installs, 2024), Pulselio, Vimetra, Coinlyzer coin recognition and others; AppBrain shows 7 apps under this account.

- The template is obvious: "AI photo / camera recognition + paywall," reskinned category after category. Pulselio's support email is Multilanguage-Translator@outlook.com, clearly carried over from a translation app; the landing page and privacy policy sit on free vercel.app subdomains.

- **Twin app Vimetra: Health Tracker & Scan** (com.vimetra.android.com): same account, same features, same vercel landing page (vimetra-app.vercel.app), and a Facebook Page (3 followers). The US Play page shows 11-06 with 1K+ downloads, and our googleplay library hasn't picked it up, so it has never charted. The recall card says it makes up 94% of US traffic and is #12 on US Trending; we couldn't verify that, and going by 1K+ downloads it is at most just getting started.

### 2. Growth levers (where users come from)

| Channel | Evidence | Confirmed |
|---|---|---|
| Paid acquisition (channel not yet determined) | The install curve is stepped (10-04, 10-08, 10-13, and 10-21 each show a jump), and the rating count is only 0.05%, with no organic content at all. But the googleads library 11-06 was checked by legal entity, product name, and domain, and returned no_ads. The Meta library (metaads) has no Page for Pulselio or Vimetra. It could be running on programmatic networks like Mintegral, AppLovin, or Unity, or it may be using a different advertiser name. | Paid acquisition pattern confirmed; specific channels unconfirmed |
| Volume in low-price markets, monetize in high-price ones | Free chart leads in MX (plus a share from VE and CO via recall cards); paid signals show up on the AU and US Top Grossing charts. This is the common tool-matrix play: buy cheap installs in Latin America and Africa to push total installs up, then monetize subscriptions in Australia and the US. | partly (MX and AU/US rank confirmed, share not verified) |
| ad monetization paid acquisition | The subscription terms say members can remove "interstitial, banner, and rewarded ads," which means free users are seeing ads, and the low-price stores can also earn back a bit of cost through ads. | Confirmed (per official site terms) |
| Store search / ASO | The title uses "AI Health Tracker", and the short description packs in heart rate, stress, HRV and skin age. Once it hit the category chart it picked up some organic traffic. | Inferred |
| Twin-version storefront test | Vimetra is another bundle from the same account and product, aimed at the US store. It's a common matrix move: if one bundle gets banned or has poor ROI, you swap in another as insurance. | Twin version confirmed; regional split strategy unverified |
| TikTok / X / Reddit / media / creators | TikHub search for "pulselio" and "vimetra" both returned 0 results; x-radar found 0 results for both terms over 60 days; Jina search only turned up store pages, APK sites and softonic, with no press coverage | No |

### III. Competitors

| Competitors | Where | Launched | Scale | How Pulselio differs |
|---|---|---|---|---|
| Google Fit camera heart rate / breathing | Big-company features | 2021 | Google Fit 370M installs (googleplay library) | Free and built in: measures heart rate with your finger, breathing from your face. Pulselio sells a paid version of the same thing. |
| Heart Rate Monitor - HeartIn(Vision Wizard) | Android | 2024-11 | 9.12M installs, #18 on the AU Top Grossing chart, #26 in the US | Finger PPG + subscription, already proven to make money, at 120× Pulselio's scale |
| Welltory | Android/iOS | 2017 | 5.99M installs, #47 Top Grossing in US | Long-running HRV / stress app, mostly fed by watch data, with camera measurement too. Much stronger brand and data history. |
| CardioLens(Ark Mobile Tech) | Android | 2025-09 | 1.75M installs, +76k in 7 days | Measures heart rate with a finger, claims it can also read blood pressure. Growing 9× as fast as Pulselio. |
| Heart Rate Monitor - iCardiac(iKame) | Android | 2026-03 | 1.59M installs, #51 Top Grossing in AU | Big publisher portfolio, finger-based. Its AU Top Grossing rank is almost right next to Pulselio's. |
| FaceVital(iKame) | Android | 2026-06 | 143k installs | Also face scanning, but the copy says "blood pressure trends." Pulselio explicitly says it doesn't measure BP. |
| Artera(iKame) | Android/iOS | 2026-07 | 120k installs | Camera-based blood pressure + tracking, with Google video ads targeting the US (see our earlier Artera report) |
| Heart Monitor / BP Diary(Shen.AI) | Android | 2021 / 2026-09 | 465k / 1 thousand | An rPPG tech provider's own app, with an SDK and clinical backing |
| Anura(NuraLogix) | iOS/Android | 2021 | Unverified (no Play library data) | The originator of "30-second selfie health checks." Added blood pressure and cardiovascular risk, licensed B2B. |
| FaceHeart, Binah.ai / Circadify, and others | SDK / B2B | 2018– | — | Sells rPPG SDKs to insurers and telehealth providers (e.g., India's Care Health app has Face Scan built in) |

The space is crowded. Camera heart-rate measurement has been a standard play since Cardiio 2012 years ago, and face-based readings were already done by Anura and FaceVital. Pulselio doesn't rank near the top on scale; the only thing it can point to is #50 on the AU Top Grossing chart.

### 4. Differentiation, and whether it's the reason it took off

1. **Face scan, no finger press** . The experience feels more "AI" than pressing a finger over a flash, and the creatives are easy to shoot (face + value overlay). But FaceVital, Anura, and Shen.AI were already doing this, so it's not exclusive.

2. **Compliance framing** . The listing says "Non-Measurement Notice: Pulselio does NOT scan or measure Blood Pressure, Blood Glucose, or Blood Oxygen" and "Not a medical device," limiting claims to heart rate, breathing, HRV, and stress, the metrics rPPG can actually estimate. Many apps in this space claim BP readings, which creates risk under Google Play's health policy and ad review. Pulselio's framing makes it less likely to be delisted or have ads rejected, a real advantage for a paid-acquisition app. But that's a condition for surviving, not why users show up.

3. **"AI health score / risk summary (Gemini) + skin age"** , wrapping the scan results in an AI interpretation layer so the $9.99–$39.99 subscription looks like it contains substance.

So differentiation isn't why it took off. It got here through the publisher's "photo recognition + paywall" template, plus paid acquisition (cheap LatAm traffic, AU/US subscriptions). The product itself has negative reviews.

### 5. Visibility and copycats

- Almost nobody knows about it yet: no press coverage, no TrustMRR listing, no discussion on X, TikTok, or Reddit. Just store pages and APK sites.

- Copycats: so far the only one I've found is its twin, Vimetra. This category is basically a group of matrix publishers (iKame, Ark Mobile Tech, QR Code Scanner., etc.) copying each other, so it's hard to tell who came first.

### 6. What others can borrow

- **Compliance copy template** : explicitly state "no BP / blood glucose / blood oxygen, not a medical device," and sell only what rPPG can really estimate. This gets you past review, lets you run ads, and reduces refunds and complaints.

- **Matrix reskins** : the same "camera / photo → AI result → paywall" code, moved into heart rate, antiques, coins, cards, calories, and other categories. Spin up a twin package in each vertical, test, and push budget into whichever has positive ROI.

- **Market mix** : cheap LatAm and Africa traffic drives total installs and category charts, while AU and US convert to subscriptions. Free users watch ads, which offsets part of the acquisition cost.

- **Very cheap periphery** : website and terms hosted on Vercel, shared support email, so the marginal cost of one more SKU is close to zero.

### VII. What I'm still unsure about

- Which channel the paid acquisition runs on: neither the Google transparency center nor our Meta library turned anything up. It could be programmatic networks, or they may be using other advertiser names.

- Actual revenue: AU Health & Fitness #50 is probably in the range of tens to a hundred-plus dollars a day. This is an estimate and hasn't been verified.

- The MX 39% / VE 22% / CO 12% traffic mix, and Vimetra's "US Trending #12": both come from recall cards, and the sources haven't been verified.

- The scale of November's continued spending, and whether Google Play throttles it because of low ratings and high refunds.
