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 ratings volume: ScreenZen at 54K against QuizDB's 137. ScreenZen also leads on review sentiment (93% vs 80%) and chart position (#139 vs unranked). QuizDB's advantage is update cadence (every 9 days vs every 3 weeks) and iOS requirement (11.0 vs 16.4). On price, rating, ads and in-app purchases 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. QuizDB sells 1 one-off in-app purchase and ScreenZen sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for QuizDB against 4.9 for ScreenZen. That said, the two scores are not equally well evidenced: ScreenZen has 54K ratings behind it against 137, so its average is the more settled of the two. Written reviews are what separate them: 80% of QuizDB's written reviews are positive against 93% of ScreenZen's.
QuizDB ships an update every 9 days, ScreenZen every 3 weeks. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
