Multiple strategies to reduce your screentime 1. Delay before opening your app: A bit of time before choosing if you need to open your distracting app. You can have the wait time increase each time you open your app. 2. Interrupt your scrolling: Check your distracting apps for short periods of time so you don't get sucked in. 3. Set an app goal and optionally block when you reach your limit. 4. Configurable for different days of the week and time by app. 5. Messages like "Is this important" before opening your app. 6. See your screen time for only your distracting apps. Don't worry about Google Maps bloating up your time. 7. Strict block your apps: Either for time ranges, after a certain number of opens or ScreenTime. 8. Locks on Settings to prevent you from changing your settings when you want to open an app. 9. Breathing and other activities to encourage you not to need to open the app while waiting for it to unlock. 10. Streaks to encourage you not to exceed your limits or override your settings.

Verdict
The clearest difference is rating: ScreenZen at 4.9 against STFU's 4.0. ScreenZen also leads on ads (none vs shown) and ratings volume (53K vs 4). STFU's advantage is update cadence (daily vs every 3 weeks). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ScreenZen sells 4 one-off in-app purchases and STFU sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
ScreenZen holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: ScreenZen has 53K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 93% of ScreenZen's written reviews are positive against 100% of STFU's, so the app with the better star average is not the one people write more warmly about.
ScreenZen ships an update every 3 weeks, STFU daily. The most recent releases landed on November 3, 2026 and October 29, 2026 respectively.
