  • 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

  • Opal: Screen Time Control2star· Aug 13, 2026

    Dislike the new update — I was finding Opal very helpful in managing my screen-time but the new update is awful. The interface is terrible and I am no longer able to remove certain apps to be included in my total screen time for a more accurate representation of my unwanted phone usage. I tried to get acclimated to the new update but have finally decided to delete it and try a different app now.

  • Opal: Screen Time Control3star· Aug 13, 2026

    New update makes it harder to use — The app was really good and ive used it for months now, but after this last update I have to sit through multiple wait screens just to get a break from the app-blocking. And the new UI is really confusing and it feels like they are going backwards. Not to mention there are tons of freezes now

  • BePresent: Screen Time Control2star· Aug 19, 2026

    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

  • BePresent: Screen Time Control2star· Aug 14, 2026

    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 Control3star· Aug 7, 2026

    Used to be better — Used to work super well but a new update made it so that my daily limits no longer work. I have to block everything manually now.

  • BePresent: Screen Time Control3star· Aug 22, 2026

    The brain’s reward system outwitted BePresent — I’ve been using BePresent for about a year. It worked very well at first, significantly cutting my screen time and improving my quality of life. In time, I replaced some of that newfound time with meditation sessions and began feeling even better. But during periods of stress (over the top right now like few other times in history) discipline can s

  • BePresent: Screen Time Control1star· Aug 20, 2026

    Scam! — This app doesn’t work well. When I would open it, the screen NEVER allowed me to go to settings and cancel. The same screen of add more apps to block would pop up. Never started the free trial, and yet I was charged money. I would never use this again.

  • ScreenZen- Screen Time Control1star· Aug 27, 2026

    Unauthorized Charge — The app just randomly charged me a $5 donation that I didn’t agree to. It was not clear at any point that I would be charged. I selected the app because it was supposed to be free. As for the app itself it’s okay and did help but it does not allow you to exclude activities from screen time. I often read my books using the kindle app. This is not the type of activity I’m tryi

  • BePresent: Screen Time Control1star· Aug 24, 2026

    Will take your money — I downloaded this app about a month ago. I had a week long trial and decided to delete the app. A month and a half later I am charged a $60 subscription fee that I didn’t sign up for.

  • BePresent: Screen Time Control2star· Aug 23, 2026

    Honestly — This is really annoying. I accidentally forgot to unsubscribe before the trial was up so I was charged $50-$60. I thought I’d give it a shot since I can’t get my money back. Well. It’s just another thing that sends notifications. It doesn’t actually stop me from using the apps that are addictive. I literally just bypass it but it keeps telling me “the app is closing” even when I’m not c

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

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

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 markets are ranked

We give each market a mark out of 100 for seven things (nobody's fixed it 20 · above the norm 15 · how angry 10 · room to build 15 · room to enter 15 · getting bigger 20 · willingness to pay 5). Then we multiply the marks together. We do not average them.

Averaging lets a market hide one bad problem behind good numbers. Multiplying means one bad mark pulls the whole score down. That is the point. A market you cannot win is still a market you cannot win, however badly it is served.

Each mark has a fixed rule. Nobody’s fixed it and willingness to pay are plain shares. Above the norm maxes out at 4 times the store’s usual rate. How angry runs from star3.0 down to star1.5. Room to enter is what the biggest app does not own. Getting bigger hits 100 at 10% growth. Room to build is different. It is a sweet spot, not a size. A market can be too small to live on, or too big to break into.

If we cannot count something, we leave it out. We never guess it. The score only sorts this list. Every other number you see on a market is counted.

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 12,728 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.
