# Can't scroll TikTok without doing push-ups: a crowded iOS category, brought to Android by a small studio

**What it is** A self-discipline tool that locks social apps and makes you do push-ups or squats in front of the camera before you can open them.

**Why it took off** "Do exercise to unlock your screen time" was already taught on iOS by similar apps and TikTok template videos. On Android there are few options, and it brought the iOS version over with a category keyword as the title, catching spillover demand in the low-barrier charts of English-speaking countries.

**C** **How you could follow** Stop building push-up unlocks; copy the playbook instead: find a category already hot on iOS and TikTok but with few Android players, use one blocking core with different unlock conditions (reading, vocab, steps) and audiences to claim the space, and acquire users via store search and POV template burner accounts.

C grade: followers need no unavailable resources, but the category is crowded on iOS while Android has gaps, and since August Kidslox, Pushup RPG and others have been filling them. The product has no moat and its revenue is invisible. The playbook is worth learning; copying the product is not worth it. Few people know about it yet

ScrollFit locks your social apps and makes you do push-ups or squats in front of the camera before you can open them. It didn't invent the mechanic: more than twenty studios already run it on iOS. It hit Google Play in Sep 2, got 20k installs in two months, and reached the top 100 of the free Health & Fitness charts in Australia, the UK, the US and Canada. It took off because there were few similar apps on Android, not because the product is special. What's worth learning is the playbook, not the product itself.

### "This app makes you do it"

In 2026 Sep 16, a user named Kia Hashemi left a five-star review on ScrollFit's Google Play page. As of Nov 6 it is still the review with the most "helpful" votes:

> "There's no skip button while it's locked. Don't tell me 'use the break card': that only gives a very short time and doesn't unlock everything... I'd rather use this than go to the gym. At the gym you have to walk over, and you can slack off and not go. This app makes you do it. Gyms charge money, this one is free."

Another review from Sep 25 is shorter: "Now I work out while scrolling my phone."

This is what the app sells: **users aren't buying fitness, they're buying a lock that's stricter than their own willpower** . The reviews praise most the fact that "you can't skip it."

### What it is

The first line of the store page: "Block distracting apps. Do push-ups or squats to unlock them. Take your time back."

- Pick the apps to lock. When you open one, ScrollFit pops up and makes you do a set first;

- 5 exercises: push-ups, squats, sit-ups, planks, wall sits. Reps and duration are set by you; the camera counts reps on the device, with no upload and no network;

- You can build modes ("lock social", "work apps only") and schedules, e.g. auto-lock from 11 pm to 7 am;

- "Take a Break": do one set for a temporary pass of 1–30 minutes, then it locks again when time runs out;

- There are also challenge stages, a body muscle map, and streak tracking.

Pricing reads "subscription or one-time purchase", with one in-app purchase at $3.99–39.99 (Google Play page, 11-06).

It's made by Raukin LLC, registered in Wyoming, USA. Its website calls it a "product studio + outsourcing" shop with a dozen-plus products: SaaS, apps, Arabic mini-games, and a Polish e-commerce site. Using the same core of "lock apps, unlock on meeting a condition," they also built SalahMode, which swaps the condition for prayer.

### How much it grew

- **Installs** : 20,490 worldwide on Google Play (11-06), +4,887 in the last 7 days; 706 ratings, 4.6 stars.

- **Curve** : per third-party estimates, the first three weeks after launch brought 250–650 installs a day, falling to 100–300 a day by mid-to-late October. Around Oct 4 there was a jump; from 10-31 to 11-03 it accelerated to about 1,100 a day, then went back to about 500 (estimated). It's "a base layer plus a few pulses"; what caused the two pulses isn't visible from outside.

- **Charts** : only on the free Health & Fitness chart. Best ranks were #28 in Australia, #46 in the UK, and #89 in the US and Canada. On 11-06 it ranked Australia 28, Canada 89, US 95, UK 96, Germany 192 that day.

- **Money** : never charted on any grossing chart; no public revenue data.

Ratings make up 3.4% of installs, which is high for a utility app; the app likely shows a rating prompt (inferred).

Notably, where its users are: ScrollFit only charts in English-speaking countries plus Germany. The older, bigger Android namesake Push Up Time: AI App Blocker (530k installs) only charts in Vietnam, Thailand and the Philippines. **The same product, but ScrollFit's users are in markets with far higher spending power.**

### Where it came from: validated on iOS first

ScrollFit's iOS version launched in 2026 Jan 22, with 3,267 ratings and 4.7 stars on the US App Store (11-06). The Android version came more than seven months later, with nearly identical copy and one extra paragraph explaining the Android accessibility service and usage access permissions.

The iOS version was itself a follow-on. The category is called "exercise to unlock screen time" on iOS, where the leader PushUp Time: App Blocker launched in 2025 September with 11k ratings in the US store. ScrollFit's package name is `scrollfit.pushup.time`.

There's a TikTok account @scrollfit.io (398 followers). A "Get ScrollFit now" post in Mar 9 got 690k views. In late August it posted two or three template videos a day, rotating three captions: "My phone won't let me open TikTok unless I do 30 push-ups 💀", "POV: opening TikTok now costs more than my gym membership 💀", "I just wanted to check one notification 😭". Each got a few hundred views, and posting stopped after Aug 29. Whether this account belongs to Raukin can't be confirmed (scrollfit.io is a parked domain). The whole category grew this way on TikTok: a batch of burner accounts and the same POV template, with some single posts reaching hundreds of thousands of views.

### Where users come from

| Channel | Evidence | Confidence |
|---|---|---|
| Moved to Android after iOS validation | iOS launched in January with 3,267 ratings; Android launched in September with identical copy | Certain |
| Google Play search and category charts | The title is literally "PushUp App Blocker" and the package name includes pushup.time. Chart ranks in English-speaking countries are steady, and the base of a hundred or two hundred installs a day outside the pulses looks organic. | Inferred, moderately confident |
| TikTok template videos | @scrollfit.io has one post at 690k views, the rest a few hundred; ownership unconfirmed | Uncertain |
| Paid acquisition | Not found in the Meta ad library; the developer email is raukin.ads@gmail.com | No evidence |

The most likely picture: dozens of similar apps and UGC accounts on TikTok had already taught "you need push-ups to scroll your phone." Android users who heard of it searched the store and found few options, and ScrollFit happened to carry that name (inferred).

### Who it's competing with

| Product | Platform | Launched | Scale | Compared with ScrollFit |
|---|---|---|---|---|
| PushUp Time: App Blocker | iOS | 2025-09 | US store 11k rating | Category leader, iOS only |
| Push Up Time : AI App Blocker(Firehawk) | Android | 2025-11 | 530k installs, +10k per week | Older and bigger, users in Southeast Asia |
| Pushup RPG: Fitness Quest | Android / iOS | 2026-07(Play) | 170k installs | Gamified monster-battling, not pure blocking |
| Workout Locker(Kidslox) | Android | 2026-08 | 36k installs | Same product from a parental-control company, same English-speaking markets, charts lower than ScrollFit |
| PushUpLock | iOS | 2025-11 | US store rating 1,255 | One goal per day; complete it to unlock for the whole day |
| Fitblock, Blocus, LockedIn, Grindlocker, RepBlock, Push to Unlock …… | Mostly iOS | 2025–2026 | 10–300 ratings each | Same thing, a whole pile of them |
| Three other apps also named ScrollFit | Android | 2026 | Small | Searching "scrollfit" gets split across them |
| iOS Screen Time / Android Digital Wellbeing | System | — | Everyone | Only timer limits, no "move to unlock" |

Pushgard's October comparison post says only three of seven rivals have an Android version. Android was clearly empty, but the table above shows it getting filled starting in August.

### Why it made the charts

1. **Nobody needs proof of demand** : iOS and TikTok already did that work.

2. **Empty on Android** : in the English-speaking health & fitness free chart, 20k installs gets you to #28–100. The bar is low.

3. **Solid product** : 5 exercise types, no skip button, short breaks only. Users praise exactly this.

4. **Cheap to build** : one studio swaps themes (workout, prayer) on the same blocking engine, so one codebase tests several niches.

Android is actually easier for this than iOS: an accessibility service plus usage access lets you block apps more flexibly than iOS's Screen Time API.

### If it were you

**C: worth learning from, not a great business by itself.** Push-up-to-unlock has 20+ iOS clones, and the Android gap has been filled since August by Kidslox, Pushup RPG and others. ScrollFit's own revenue isn't visible. What's worth copying is the play: find categories already educated on iOS and TikTok but thin on Android, then claim them with one engine and swappable themes.

- **Good fit for** : a one- or two-person studio that can write Android and ship an app a month, ideally one that already has a reusable "block + conditional unlock" core.

- **Bad fit for** : anyone making another "do push-ups to unlock" app. There's no moat, and the name and keywords are taken (even "ScrollFit" has four namesakes). Also anyone hoping for steady income: no one in this category has published real revenue.

- **How to do it** : don't copy the exercise, change the condition and the audience. Unlock conditions could be reading a few pages, memorizing ten words, walking a step goal, or reading a passage of scripture (prayer and Bible apps already exist, so check first). Audiences could be students during exam season or parents setting limits for kids. Copy ScrollFit's core: no skip button, short breaks, scheduled modes. Charge a subscription plus a one-time lifetime purchase.

- **How to get users** : put the category term straight in the title and package name ("XX App Blocker") to capture store search. On TikTok, run a few POV-template videos a day from a small account to ride existing category interest instead of creating demand. Trigger the rating prompt after the user completes a set.

- **Timing** : this "iOS first, Android catches up" window usually lasts only a few months. The exercise-based version is already late, so a condition-swap variant should launch before the 2027 New Year "new year, new goals" push. If you miss that, target the late-February back-to-school season.

- **Signs you've misread this** : ① ScrollFit or Workout Locker charts in any English-speaking store's Top Grossing, which means the category really makes money on Android and deserves a head-on fight. ② ScrollFit's daily installs stay above several hundred after December without being pushed down by Kidslox, which means the English Android market isn't saturated. ③ Google builds "complete a task to unlock" into Digital Wellbeing, which means the whole category is off limits.

## ScrollFit - PushUp App Blocker (Google Play, scrollfit.pushup.time) research report

Date: 2026-11-06. Developer Raukin LLC (raukin.com, describes itself as "product studio + outsourcing", 14 products live: SaaS, apps, Arabic mini-games, Polish e-commerce). Developer email raukin.ads@gmail.com (googleplay library, app table).

### One line

Do push-ups / squats with the front camera, and the blocked social apps unlock once you've done enough. The iOS version launched first (2026-01-22 US store, 3,266 ratings, 4.70 stars, iTunes lookup 2026-11-06), and the Android version went live on 2026-09-02. It's a **port of a category already validated on iOS to Google Play, which has far less competition** .

### 1. Data

- Installs: 20,490 (googleplay library app_profile, 2026-11-06); last 7 days +4,887. Ratings 700 (about +230 per week), 4.6 stars.

- Curve since launch (AppstoreSpy estimates, app_day_ext): 9-14 577 → 9-24 5,293 → 10-04 10,183 → 10-28 15,601 → 11-05 20,490. The first three weeks averaged 250–650 a day. In mid-to-late October it fell back to about 100–300,10-04 a day, with a jump around 2,202 extra per day averaged in. It accelerated again around 10-31–11-03 (about 1,100 a day), then settled at about 490 a day from 11-04–05. It isn't a smooth curve. It's a base level plus a few spikes.

- Charts (chart_rank, from 10-29): best health & fitness free rank #28 in AU, #46 in GB, #89 in CA/US, #103 in DE. **It charts only in English-speaking countries plus Germany** . By comparison, Push Up Time charts on Android only in Vietnam, Thailand and the Philippines, and Pushup RPG in Vietnam, the Philippines, Taiwan, Japan and Poland. ScrollFit's users skew clearly "Western".

- The rating-to-install ratio is 3.4% (700/20,490), high for a utility, which suggests an in-app rating prompt (unverified). Most review content reads as genuine use. The top-liked Play reviews from mid-September praise "no skip button, break cards only for short periods".

- Monetization: in-app purchases $3.99–$39.99 (data card). It hasn't charted in any Top Grossing list, and no revenue is public.

### II. Competitors

This is the category that got overrun on iOS from the second half of 2025: "exercise to earn screen time / Earn Screen Time".

| Product | Platform | Launched | Scale | How it differs from ScrollFit |
|---|---|---|---|---|
| PushUp Time: App Blocker(Mutasim Ibrahim) | iOS | 2025-09-12 | US store rating 11,566 | Category leader, iOS only (pushuptimeapp.com), grants time per 15/30/60/120-minute window. ScrollFit's positioning is nearly a copy, and both use the package name pushup.time. |
| Push Up Time : AI App Blocker(Firehawk) | Android | 2025-11-16 | 530k installs, +10k a week, 6,522 ratings | A same-named copycat on Android that's been around a year, far bigger, but its users are in Southeast Asia. ScrollFit started later and is smaller, but ranks higher in English-speaking countries. |
| Pushup RPG: Fitness Quest | Android/iOS | 2026-07-31(Play) | 170k installs | Gamified (leveling, fighting monsters), not a pure blocker |
| Workout Locker(Kidslox) | Android | 2026-08-06 | 36k installs | Same product from a larger parental-control company, charting #126–151 in GB/CA/AU, lower than ScrollFit |
| PushUpLock(PopChunk) | iOS | 2025-11-20 | 1,255 rating | One daily push-up goal unlocks the whole day |
| Fitblock / Blocus / LockedIn / Grindlocker / Merite / Tonic / Be Serious / RepBlock / Kaivoo / Tacet / RepUnlock / Push to Unlock … | Mostly iOS | 2025-01 ~ 2026-07 | Ratings 10–300 each (appstore library) | Samey clones, a whole crowd |
| Pushscroll, ScrollToll, Pushgard, FitScroll | iOS + some Android | 2025–2026 | Not verified | ScrollToll and Pushgard price by "minutes earned per exercise". Pushgard's own comparison (2026-10) says "Android selection is much narrower": of 7 rivals, only 3 have Android. |
| Name collisions: ScrollFit: Scroll Time Blocker (io.texense.wellbeing), ScrollFit: Focus & Screen time (com.scrollfit.fitness), Scrollfit (com.eumule.scrollfit) | Android | 2026 | Small | Same name, different companies. Searching "scrollfit" gets split across them. |
| Big-tech features: iOS Screen Time / Android Digital Wellbeing | System | — | full range | Only timers and limits, with no hard "move to unlock" gate |

Verdict: **the category isn't theirs. It's the Nth copycat.** Its edge is the gap between Android and the English-speaking market.

### 3. Growth tactics

1. **iOS tested first, then ported to Android (confirmed)** : on iOS since 2026-01-22 with 3,266 ratings. Android since 9-02, same name and copy (the Play description closely matches iOS, and it even explains the Android accessibility service and usage-access permissions). TikTok has already taught the category to users through dozens of similar apps and UGC accounts, but Android users who've heard of these apps have few to choose from in the store.

2. **Store search (likely, not directly verified)** : the package name scrollfit.pushup.time and the title "PushUp App Blocker" target phrases like "pushup app blocker" and "push up time" directly. Its steady rank on the AU/GB/US/CA health & fitness charts and its baseline installs on non-spike days (100–300 per day) look more like store search plus organic chart traffic.

3. **TikTok brand account (possibly; ownership unconfirmed)** : TikTok handle @scrollfit.io (display name ScrollFit, 398 followers, 68 videos). 2026-03-09 a "Get ScrollFit now" video with 690K views; in late August it posted 2–3 templated POV videos a day ("opening TikTok now costs more than my gym membership"), each getting a few hundred views, then stopped posting 8-29 (before the Android launch). The scrollfit.io domain is a Hostinger parked page, so we can't confirm it belongs to Raukin. Across the category, TikTok growth runs on "small account matrices + templated videos" (@derek.fitscroll, @nick.fitscroll, @grindlocker with 0 450K views, etc.). This is the standard playbook for peers.

4. **Paid ads (none seen)** : the metaads library has no advertiser records for ScrollFit or Raukin. The developer email is raukin.ads, which suggests an awareness of paid distribution, but there's no evidence of spend. The reasons for the two spikes on 10-04 and 11-01–03 are unknown (possibly ads, featuring, or a single video).

5. **X / Reddit / press** : x-radar shows 0 posts mentioning "scrollfit" in the past 90 days. On Reddit there are many self-promotion posts from developers of similar apps (r/apple "Push to Unlock," r/ProductivityApps), but none for ScrollFit.

### 4. Why it made the list

- Demand for the category is already validated on iOS and TikTok (PushUp Time has 11k ratings on iOS, and similar TikTok videos routinely get hundreds of thousands of views). ScrollFit is capturing spillover demand.

- Android 上空:Pushgard 2026-10 的对比文直说 Android 选择窄;Google Play 上同类只有 Push Up Time(用户在东南亚)、Workout Locker、Pushup RPG 几家,英语国家健康健身榜第 28–100 名门槛很低,2 万安装就能挂上。

- The product is harder-edged than most clones: 5 exercise types, no skip button, and modes + schedules + a "Take a break" short pass. Reviews specifically praise that it "can't be skipped." Ratings sit at 4.6–4.7.

- One studio running a multi-product pipeline (SalahMode is the same "block + conditional unlock" core with prayer as the theme). Reusing code makes it cheap to test the category.

### 5. Differentiation

Compared with iOS competitors there's almost no differentiation: positioning, copy, and features are all category standard, and it uses time windows rather than per-use pricing. The real difference is **channel position** . It's one of the few that shipped an Android version and got users into a high-value English market. That Android gap is why it broke out, and the product itself is only adequate.

### 6. Visibility

Few people know about it yet: no public revenue, no X discussion, no press coverage. It only shows up on aggregator sites like Softonic and AppBrain, and in competitor Pushgard's comparison article. But the category is already crowded on iOS (20+ apps in the table above), and the Android gap is being filled by Workout Locker (Kidslox), Pushup RPG, and others.

### VII. What to take away

- "A category TikTok has already taught on iOS → port it to Android": Android's accessibility service and usage-access permission make blocking easier to build than iOS's Screen Time API, so the development bar is actually lower. The English-speaking category charts are also easier to crack.

- Put category keywords directly in the package name and title.

- Reuse the same blocking core with different themes (exercise, prayer, study).

### 8. Not sure

- Whether the @scrollfit.io TikTok account belongs to Raukin, and where the two spikes on 10-04 and 11-01–03 came from.

- Payment conversion and revenue (in-app purchases $3.99–$39.99, not charted on Top Grossing).

- Retention: ratings keep rising by 20–45 per day, but install counts update in tiers, so real daily new installs need a longer observation window.
