# A blood-testing company that raised $55.9M built an app for its existing members, then used a thousand ads to push it up the charts

**What it is** The members' app for a US at-home blood-testing subscription company ($79/month, a painless sampler that attaches to the upper arm, its own lab, testing 25+ markers). It's for viewing results, tracking trends, and chatting with the AI Coach.

**Why it blew up** Old members moved in first and wrote a batch of reviews when it launched in October. After the Series B hit, it pushed Meta creator-partnership ads from dozens a month to 1,089 in October, then added outdoor screens and celebrity endorsements. Ratings climbed 20-30 a day from November.

**D** **How you could ride it** You can't copy the product, but you can copy the playbook: an affiliate program that works as a creative factory paid on ad spend, one claim paired with one filmable action, and landing pages split by audience. Or build a tool that pulls blood test results from every lab into one trend view.

D grade: the surge was driven by paid acquisition at scale, funded by a $55.9M raise, plus in-house labs and celebrity backing. Followers can't match that. Function, Superpower and other leaders in the category have raised more, and the companies have been widely covered. Only the playbook is worth studying. Public / widely discussed

Rythm Health's iOS app has been live for a month, and its US store rating went from 34 to 166, with 131 new ratings in the last 7 days. It looks like a new app taking off. It isn't. It's a subscription company that mails blood-test kits every month, and the app is just the member companion. What pushed the numbers up was 1,089 new Meta ads it launched in October. Indie devs can learn an ad playbook from it, but there's no product here to copy.

### a red button stuck to your arm

2026 Oct 17, Business Insider profiled an ER doctor, Jonathan Andrews. He had never tested his testosterone, started six weeks earlier, and has tested three times so far. He didn't go to a lab or get a needle. He stuck a button about the size of a coin to his upper arm, made breakfast while it sat for five minutes, and the blood draw was done on its own. The device is Tasso+, an FDA-cleared Class II medical device. Over the past year, shipments grew from 2M to 4M units.

In the same article, DJ Diplo says on camera in a YouTube video: "This is the future. Everyone should know what's happening in their body." That was a Rythm ad, and he's a brand ambassador.

Rythm sells that button plus a lab. Every month it mails you a collection kit. You stick the button on your arm at home, FedEx picks it up, and it goes to Rythm's own lab. Results come back in 48 to 72 hours, covering 25+ markers, for $79 a month. In October 7, the iOS app launched.

### What it is

It's a member app: register your kit, view results and trend charts, chat with an AI Coach about your markers, change your billing date, or skip a month. The app is free with no in-app purchases. Subscriptions are bought on the website (HSA/FSA cards accepted), so the app has never charted in the Top Grossing list and Apple can't see its revenue.

The company isn't new. Its web member system has been running for a while, and the site says "4.8 stars, 3,000+ reviews, 15M results delivered." It has raised about $55.9M total. In June 2026 it closed a roughly $31.1M Series B (per PitchBook and CB Insights). It has about 50 employees.

### How the rating climbed

| Date | US overall rating | Added that day |
|---|---|---|
| 10-28 | 34 | — |
| 10-31 | 40 | 5 |
| 11-01 | 53 | 13 |
| 11-03 | 89 | 28 |
| 11-05 | 138 | 25 |
| 11-06 | 166 | 28 |

App Store US rating, 10-28 to 11-06. Best Health & Fitness free-chart position: #52. Not on the overall chart.

It breaks into two waves.

**Wave one: old members moving over.** Of the 18 written reviews visible on the store page, 14 were posted from October 9 to 12, in the first few days after launch. Nearly all read like longtime users: "I've used Rythm for a year, now it's all in one app, so much easier" "Finally no more going to the website" "So happy Rythm finally made an app!!!" "I test every month." That group was ready-made, and they filled the top of the store page on day one.

**Wave two: new ratings from November** , twenty to thirty a day, but almost all star-only with no text. After mid-October, only 4 text reviews were left. One was a one-star complaint about crashes on iPhone 12. Three days later that user changed it to "Fixed, dev's fast." The timing lines up with Rythm's October ad push.

### Where users come from

**Meta creator-partnership ads are the main engine.** According to the third-party ad library admanage.ai (updated 11-06), Rythm has run 2026 ads on Facebook and Instagram since March 2,604. 2,587 are still live. 1,637 of them are partnership ads posted under creator names, and 57% are video. New ads per month: May 36, June 344, July 392, August 230, September 493, October 1,089. Spending ramped up as soon as the Series B money landed, and it doubled again in the month the app launched.

Nearly every ad opens with the same line: "Rythm is the world's easiest blood test…" Landing pages are split by audience: testosterone/TRT, thyroid, PCOS, GLP-1, iron, HSA/FSA discounts.

**Where the creative comes from: the affiliate program is a creative factory.** Its creator recruitment page is blunt. You submit at least 2 finished short videos a month that can run as ads as-is, and you attend a coaching session every week. In return you get a free membership (list price $1,200 a year), 10% of the ad spend on videos you supply, and $50 per first order. The page also says "Many people earn $5,000+ a month, top earners $50,000." So creators aren't just posting to their own accounts. They supply creative, the brand spends money to scale it, and creators take a cut of the spend. Users on Reddit's r/Biohackers share $20 referral codes.

**The rest is brand buzz.** Celebrities include Diplo, NFL player Odell Beckham Jr., and Spanx founder Sara Blakely. In October it ran outdoor digital screens (reported by Publisitios). It did live blood draws at coffee shops. It became an official partner of a "whose biological age is youngest" contest. Founder Robby Wade (a triathlete) did a podcast tour. The website now offers 7% off the first kit, with a $55.30,90 money-back guarantee within 10-30 days.

The official TikTok account @rythm has 39.7k followers and 781 videos. No breakout hit turned up. App Store search contributes very little.

### Why the ads work this well

- **One line, one action.** "The world's easiest blood test": on camera, stick it to your arm, press the button. Three seconds and the point is made. The same line runs across two thousand-plus ads. Only the faces change.

- **The math works.** $79 billed monthly comes to nearly $950 a year. The high customer value can cover the 10% creator cut plus the $50 first-order bounty.

- **It caught a trend.** In 2026, health-maxxing and longevity spending were trending in the US (STAT in May and Fast Company in September both wrote about it). Testosterone prescriptions among young men have more than doubled since 2018 (Business Insider, citing Truveta). The TRT and GLP-1 crowds are exactly what its landing pages target.

- **Reviews are split.** Some Reddit users say it's far more convenient than going to Quest. Others say "almost every month over 6 months something broke" and that its numbers run systematically higher than Quest's. An r/ehlersdanlos poster warned that it's running ads targeting that patient community. One reviewer said "best blood draw experience, but too few markers, and testing monthly is too often." Retention numbers aren't visible from outside.

### Who it's competing with

| Competitors | Scale (US App Store) | How it differs |
|---|---|---|
| Function Health | 25k ratings; raised another $450M in 2026 | Venous draw at Quest, 100+ markers per test, $365 a year for 1–2 tests |
| Superpower | 1,733 ratings | $199 a year for 100+ markers, with a supplement store; at-home draw costs an extra $119. The site has a dedicated "Superpower vs Rythm" page. |
| SiPhox Health | Not verified | The most direct rival: at-home painless blood draw, $99 for the first kit then $124, tested quarterly |
| Everlywell / LetsGetChecked | 10k / 9,473 ratings | One-off test kit, not a monthly subscription |
| MyQuest / MyLabcorp | 525k / 109k ratings | The lab's own results app |

The Tasso+ button isn't unique to Rythm. Telehealth companies Hims & Hers, Balance My Hormones and Maximus also use it (Business Insider).

This category has money, crowds and headline funding an order of magnitude bigger than Rythm's. Revenue isn't public, but the company has been written about by media and rivals many times.

### If it were you

**Verdict:** this isn't an app story. It's a funded testing company buying traffic. The app's ratings are a side effect of ad spend. To copy the "at-home blood test subscription" you'd need lab certification, doctors to sign orders, logistics, and a multimillion-dollar ad budget. Indie devs and small teams don't have those.

**Who it fits:** two types. First, teams that already sell a high-ticket, monthly-repurchase product (supplements, telehealth, pets, skincare) can lift its ad playbook directly. Second, software builders watching the gap it leaves. Users complain about "too few markers" and "testing too often." Quest, Labcorp, Function and Rythm results are scattered across five or six apps and PDFs. A tool that imports all your blood test reports, plots them on one trend line, and explains them with AI wouldn't touch a lab, and wouldn't compete for the kit (inference; I found no size data for products like this).

**Who it doesn't fit:** small teams wanting to build hardware, labs or medical services, and anyone with no ad budget counting on organic store traffic.

**How to do it:** if you're copying the playbook, three things. Write the affiliate program as "submit 2 ready-to-run videos a month, take 10% of the ad spend on your footage, and join one call a week." Pair one claim with one action the camera can capture. Split landing pages by audience, and run hundreds or thousands of ad variants from one script. Also, sell the subscription on your website and keep the app as a member service, so you don't pay Apple's 15–30% cut.

**How to get users:** creatives come from creators, traffic gets amplified through Meta partnership ads. Before launch, bank your existing users. Ask them to leave reviews in the first three days so the store page is full from the start. If you're building the reporting tool, go to r/Biohackers and TRT and GLP-1 communities, where people already share their lab results.

**How much time you have:** the playbook isn't timing-sensitive; you can use it any time. For the aggregator, the at-home blood test subscription has kept expanding over the past two years. The more reports users hold and the more scattered they are, the sooner you should claim "all my results in one place."

**Signs you've got it wrong:** ① after Rythm stops buying ads, the app still adds 20+ ratings a day, which would mean the app itself is pulling in new users and isn't just a shadow of ad spend; ② by mid next year its live ad count drops by more than half, or layoffs are reported, which would mean the creative-factory math never worked; ③ Function or Superpower ships a way to import third-party lab results, and the aggregator gap closes.

Date: 2026-11-06 data card: /home/ljr/fanout/why/cards/ios_6749600204.json

### One line

Rythm Health is a US subscription company that mails an at-home blood-draw kit once a month for $79/month, testing 25+ markers. Users draw blood with the Tasso+ upper-arm vacuum device at home, the sample goes back to the company's own CLIA/CAP lab for analysis, and an AI Coach helps interpret the results. This iOS app (launched 2026-10-07) is **not a new product** . It is a **new version of the membership app** from a company that has raised about $55.9M and has been running heavy Meta ads for 2026 years. The app rating started climbing in November, mainly because the parent company pushed hard on ads in October (1,089 new Meta ads that month, plus outdoor digital billboards), and because existing members gradually moved over to the newly launched app. This did not grow organically inside the App Store.

### 1. What the data shows

- App Store (our appstore library, us): overall rating 34 (10-28) → 166 (11-06). Daily new ratings rose from 10-31 to 5 starting 11-03, running at 24–28 per day, 131 new ratings in 7 days, averaging 4.87. Highest on the Health & Fitness free chart: #52. It did not chart overall or in Top Grossing.

- Not charting in Top Grossing is expected: the subscription is checked out on the website ($79/month, HSA/FSA eligible), the app has no in-app purchases, so Apple's grossing chart does not see its revenue. The app's role is registering the kit, viewing results, and chatting with the AI Coach (App Store description; support.rythmhealth.com).

- iTunes lookup: current version 1.0.7 (2026-10-28). This is the only app under the developer account.

- The membership system existed before the app: the web version app.rythmhealth.com has been running for a long time. The site states "4.8 stars, 15M+ results delivered" and "3k+ reviews" (rythmhealth.com, rythmhealth.com/reviews). A promoter's Instagram copy reads "The new Rythm app brings enhanced personalization, an improved AI health coach, and a sleek new dark mode" (instagram.com/reel/DeXjBv1C0lF), indicating this is an app overhaul or relaunch. So part of the rating comes from migrated legacy members, though the share is unverified.

### 2. Competitors

| Competitors | Form | Launched | Scale | How Rythm differs |
|---|---|---|---|---|
| Function Health | iOS + web | App 2024-08 | iOS us 25,132 rating (appstore library); raised another $450M in 2026 (Athletech News) | Get venous blood drawn at Quest, test 100+ markers for $365/year, test 1–2 times a year. Rythm is at-home draws, monthly testing, fewer markers. |
| Superpower | iOS + web | App 2026-01 | iOS US 1,733 rating | $199/year for 100+ markers with an action plan and supplement store. An at-home draw costs an extra $119. The site has a dedicated page, "Superpower vs Rythm" (2026-07-13). |
| SiPhox Health | Web + app | Around 2023 | Not verified | Also painless at-home blood draws, $99 for the first box and $124 after, tested quarterly. The most direct like-for-like competitor. |
| Everlywell | iOS + web + retail | App 2022 | iOS US 10,005 rating | Fingerstick kits sold per test, not as a monthly subscription |
| LetsGetChecked | iOS + web | App 2020 | iOS US 9,473 rating | One-off test kit, leaning toward medical screening |
| Hundred Health, Mito Health, etc. | iOS / web | 2025 | Hundred Health 304 rating | The "annual fee + big panels" model |
| MyLabcorp, MyQuest | iOS (big companies) | 2014 / 2018 | 109k / 525k ratings | Traditional lab results app; requires a venous draw at a clinic |

Takeaway: this category is very crowded, and the leader (Function) has raised far more than Rythm.

### 3. Where users come from (growth levers)

1. **Meta creator-partnership ads (core)** : per admanage.ai (updated 2026-11-06), Rythm has run 2,604 Facebook/Instagram ads since 2026-03, with 2,587 currently active, 1,637 of them partnership ads with creators, 57% video, mainly targeting the US. New ads per month: May 36, June 344, July 392, August 230, September 493, **October 1,089** . October is the month the app launched and the month before ratings took off. Nearly all ads use the same line: "Rythm is the world's easiest blood test…" Landing pages are segmented by audience: TRT/testosterone, thyroid, PCOS, GLP-1, iron, HSA/FSA discounts, and more.

2. **Creators as an ad-creative factory** : the affiliate program (partners.dub.co/rythmhealth) requires each creator to deliver at least 2 ready-to-run short videos per month and attend weekly coaching. Creator rewards: a free membership (worth $1,200/year), **10% of the ad spend used to boost their video** , and a $50 commission per first purchase. In other words, creator UGC is licensed and then amplified with brand money. Reddit shows users posting $20 referral codes (r/Biohackers). On Facebook, UGC agencies also use Rythm as a case study to recruit clients.

3. **Celebrity and athlete endorsements** : the site and ads feature Diplo, Odell Beckham Jr., and Spanx founder Sara Blakely. Sports Illustrated's Facebook page boosted its posts. Ad copy also mentions Jesse Itzler and athletes who used it after injuries.

4. **Outdoor digital billboards** : Publisitios (2026-10-30) reported on its DOOH campaign, pitched as "The World's Easiest Blood Test," with timing that overlaps the rating surge.

5. **Offline events and competitions** : on-site blood-draw activations at coffee shops (ad copy: "activations"); official partner of the Younger Biological Age Competition (LinkedIn, 2026-10-07); founder Robby Wade (triathlete) has appeared on multiple podcasts and filmed short videos with Morgan Housel.

6. **Price promotion** : the site currently shows "LIMITED TIME 30% OFF," with the first box at $55.30. Also a 90-day money-back guarantee and HSA/FSA eligibility.

7. **TikTok** : the official account @rythm has 39,738 followers, 781 videos, and 698k total likes (TikHub). TikTok is one source of creative, but no breakout video was found.

8. **App Store search** : minimal effect, ranking only #52 in its category. Search is not a major traffic source.

9. Our metaads library does not track Rythm, so the ad data above comes from the third-party admanage.ai and was not cross-checked against our own library.

### 4. Why it took off

- **Money-driven growth:** about $55.9M raised in total (PitchBook, CB Insights; 2026-06 Series B about $31.1M, Form D 2026-07-28). After the Series B, ads ramped sharply starting June, doubled in October, alongside the app launch and outdoor billboards. Headcount 50 (Revelio).

- **The product taps a real pain point: "no needles, no lab visits"** . Tasso+ upper-arm vacuum draw, FedEx pickup, in-house lab, results in 48–72 hours. The core line "the world's easiest blood test" is clear in one sentence and works well in short video (footage of pressing the device to the upper arm and pressing a button is enough).

- **The subscription model matches the ad spend** : $79 × monthly repurchase, with a high customer value. Creator commissions tied to 10% of ad spend and $50 per order can fund large-scale paid acquisition.

- **Timing** : 2026 is a boom year for "health-maxxing / longevity" spending (STAT 2026-05, Fast Company 2026-09). Business Insider 2026-10 reported men lining up to test testosterone with Tasso, and the TRT/GLP-1 audience is exactly what its landing pages target.

- **Open questions on retention** : Reddit reviews are split. Some say it is far more convenient than Quest; others say "6 months of problems almost every month," with values systematically higher than Quest. On r/ehlersdanlos, someone posted a PSA claiming it targets their community with ads. Wellnessdaddy's review: "best blood draw experience, but too few markers and testing monthly is too frequent."

### 5. Differentiation

- Compared with Function and Superpower: instead of testing as much as possible at once, it does **about 25 markers at home each month, painless, to track trends** , with a lower entry price ($79, versus their annual fee plus a trip to a clinic for venous blood).

- Compared with SiPhox and other at-home draw players: **the lab is its own** (the whole chain from kit to analysis is in-house, enabling faster and cheaper results), results come faster (48–72h), the price is lower, and it adds an AI Coach.

- This differentiation **is a necessary condition for growth, but not the main driver** : "the easiest blood test" gave paid acquisition an extremely shootable creative, while what really pushed volume up was large-scale creator buying after the funding round. The app itself (AI Coach, dark mode) is a membership add-on and did not independently drive growth.

### 6. How many people know about it

- Revenue is not public (the ZoomInfo estimate of $250M is unreliable). But the company has been widely covered: STAT, Fast Company, Athletech News, and several funding databases. Competitor Superpower published a dedicated comparison page, and there are many reviews and Reddit discussions.

- The at-home blood-draw subscription category is already crowded (Function, Superpower, SiPhox, Everlywell…). So this is not an unknown opportunity.

### 7. What others can borrow

- Turn the affiliate program into an "ad creative factory": creators deliver 2 ready-to-run short videos per month, paid 10% of the ad spend those videos generate, with weekly coaching calls. This lets a brand steadily get hundreds of partnership-ad creatives at low cost.

- One-line claim plus a filmable action (press the device to the upper arm, push the button), one copy set spread across 2,800 ads, landing pages segmented by audience (TRT, thyroid, GLP-1, PCOS, HSA).

- Check out on the website and use the app purely for membership service, avoiding Apple's commission. The App Store rating is a byproduct.

### 8. Still unclear

- How much of the app rating comes from new members versus migrated legacy members; whether the app prompts users for reviews.

- Real subscriber count, retention, and customer acquisition cost (CAC).

- Third-party ad library figures were not cross-checked against our library; our metaads library does not track Rythm.

- Whether there was an older iOS app (the promo copy says "new Rythm app," but the developer account only has this one app; the old version may have been removed or the service was web-only before).
