Watching: screen time / app blocker variants that unlock apps by completing a task (rest, push-ups, scripture reading). Big companies are buying installs and indie devs earn little; newcomers rely on mechanic differences and organic GP traffic.

Grouped by store. Each group starts with the charts that can be graphed (real curves, data dates below the chart), then the scanner's original notes and source links.
Qualifying list 1 pieces of evidence · 2 products with curves
- Crossed the threshold (11-06): MinuteBack: Screen Time (GP com.minute.back, developer FocusOnSharing, site minuteback.fit, launched 9-16). Today's new ratings were 899, 5 times the usual rate. Cumulative 226,542 installs, 7 days +35,123. Rating 9,617, 4.79★. Free with ads, no in-app purchases. It's also on the App Store (6812306067) but has only 2 ratings, so growth is almost all on Android. It's not in the Google ad library, and the Meta keyword table doesn't cover it, so whether they're buying ads is not visible.

- Same direction (GP, 7-day installs): BePresent (Screen Detox Inc, the same company behind [016] BibleScroll) +29,096, 266k cumulative; Opal +24,163 (#84 in gb Productivity Top Grossing); Push Up Time: AI App Blocker (unlock by doing push-ups) +9,408, 530k cumulative; ScrollFit (same mechanic, launched 9-02) +4,887; Earnie (kids) +5,324. On Product Hunt, Orbit's “Earn every app unlock” placed #4 on the 10-27 daily chart with 225 votes.
Indie product revenue (TrustMRR)1 evidence · 2 products with curves
- Paying examples: on indie, the only comparable paid products are KeepFocus at $419 and Shutout at $385 (30 days). One German iOS screen-time app listed for sale self-reports MRR of $6.7–7.5k (no data source; see [067]).
Other sources (official sites, press releases, web pages) 1 pieces of evidence
- BePresent's approach is to graft “put down your phone” onto another need (BibleScroll: “read scripture instead of scrolling”), and it runs on influencer-driven Meta ads, 300+ of them.
My take
The top players in this category (Opal, BePresent) are venture-funded companies that hold iOS positions with the Screen Time API and paid acquisition. Two openings look available to indie developers. One is Android: iOS has the Screen Time API and a concentrated competitive field, while MinuteBack grows almost entirely on GP, with Android blocking built on accessibility services. The other is the “what you trade for the unlock” mechanic (exercise, scripture, vocabulary, chores). Each mechanic maps to a specific audience, and it could combine with the widget-learning angle in [022] or faith-based angles in [016]. The revenue evidence is weak, though: MinuteBack monetizes through ads, and indie comparables each make only a few hundred dollars.
What would upgrade it
Either an indie or listed app in the “unlock by doing something” mechanic hits $3k+ within 30 days, or MinuteBack adds in-app purchases and reaches a Top Grossing chart in any store. Kill signal: MinuteBack's 7-day installs fall below 10k within two weeks.
Who it's for
An indie developer who can build an Android accessibility service or an iOS Screen Time API integration, paired with a specific audience (students, churchgoers, fitness people).
Should every product builder know this?
No.
