    Not that much benefit over phone’s screentime settings. — I’m two weeks in and deciding whether to sign up for the year subscription, and leaning towards no. The primary mechanism of the app is setting an intention for the apps that drive a lot of your screentime and then when you go over that intention it makes you override a guilt-inducing reminder. The intentions are number of opens and time

    Not actually blocked — It’s great that there’s an option to unblock if you need something, but unlimited breaks means that nothing is actually blocked at all! Also I found that the way that the app limiting works encouraged me to use my apps more, based on a feeling of scarcity. Like, if it’s only open for five minutes each time, I’d better use it during those five minutes! I hope this is a gr

  • Opal: Screen Time Control2star· Aug 6, 2026

    So many bugs, so little time — I used to love this app so much. With the recent update I wanted to give it a try again (because it was buggy before). I’ve always had issues with their time limits so to circumvent the issue, I do a separate rule for each app I want to limit (it’s only two, so not a big deal). With the new update, Opal is now constantly giving me a halfway there notification even wh

    Overpriced for what it offers. — Poorly designed. Very easy to circumvent. No real engagement. Very overpriced. Many apps that do similar things in a much more engaging and rewarding way. Very difficult to cancel or be refunded.

  • Refocus: App Blocker & Lock1star· Aug 15, 2026

    Terrible options — Hard to use and could not block websites.

  • Opal: Screen Time Control2star· Aug 15, 2026

    Dislike the update — I really enjoyed the opal app when I first downloaded it. The layout made sense and it was intuitive to use. And it worked well! Since the recent updates though it has been glitchy—sometimes keeping things blocked outside of the set hours or not blocking things when they are supposed to be blocked. And the new layout is confusing and difficult to navigate. I still can’t figure

Who’s in it

All 16 apps counted in this market · 2026-09-02.

Apps count as part of a market for 90 days after they last appear in it. Installs are Google Play's own count, last captured 2026-09-13. 9 of 16 apps have an Android listing we could match. A dash means we could not pair the two stores, not that the app is absent from Play.

What they charge, and what it costs them

Prices from Apple’s public pages; the share counts payment-mechanics language only.

What each one owns, where each is exposed

Owns. Largest reach in category at 82,117 ratings; brand-name recognition; 5 IAP tiers up to $99.99

Exposed. 67% negative rate — highest among scaled apps; June 2026 v4.0 update destroyed UX, broke limits, reset streaks, and locked features behind new paywalls; paying subscribers openly canceling

Owns. Novel friction mechanic (exercise to unlock); 11,498 ratings showing real reach; 7 IAP tiers up to $59.99

Exposed. 63% negative rate; motion detection unreliable; hardwall paywall with no free tier option; $28/yr entry price draws explicit resentment

Owns. Accountability-partner feature; 7,969 ratings; no IAP friction

Exposed. 55% negative rate — at the corpus norm; VPN slowdown complaints; support bottlenecked to email; popup-ad feel erodes trust

Owns. 7 IAP tiers up to $89.99; 6,200 ratings; moderate 48% negative rate

Owns. 18% negative rate — best among large-reach apps; 44,237 ratings; no IAP complexity

Owns. 4% negative rate — lowest in category; 43,668 ratings; 4 IAP tiers up to $40

Exposed. Small sample warning signal: very low negative rate may reflect low complaint volume rather than deep satisfaction; wishlist ratio elevated category-wide suggests feature ceiling

Refocus: Block Apps & Websites

Owns. 8% negative rate; 10,232 ratings; 7 tiers up to $59.99

Exposed. Lowest negative rate among multi-feature apps but small captured sample; unclear whether stability holds at Opal-scale load

How this is counted

Every number is arithmetic over the reviews we hold, re-counted weekly: nothing modelled, nothing scored. Themes come from a frozen pattern classifier rather than a model reading reviews, so the same review always lands in the same bucket. A market rate is pooled across every app here; the store rate is the same count across 12,743 apps. A complaint is only called a gap when at least half the market carries it, at least 20 reviews are behind it, and the market’s rate is elevated above the store’s, the same cutoff used everywhere on this site, because a problem concentrated in one app is that app’s bug, and a problem every app on the store shares is nobody’s gap.
