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

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

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

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.
