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.

For chess players who want to actually get better. Endless scrolling steals the hours you'd rather spend improving. Chess Shield blocks the apps that eat your chess time. Try to open one, and a puzzle takes over the screen. Solve it to get past. Every solve moves your ELO. HOW IT WORKS Pick the apps you reach for when you meant to study. Instagram, TikTok, X, whatever's eating you. When you try to open them, a puzzle takes over. Solve it to unlock the app for a few minutes. The puzzles match your level. Type your chess.com or Lichess ELO and we'll start there. Or skip the input and we'll test you with three puzzles. From then on, every puzzle is challenging enough to make you think, solvable enough that you'll get there. Insights show you which tactics keep tripping you up. Your ELO moves in real time on every solve. FREE INCLUDES – Unlimited puzzles, matched to your ELO – 6 starter tactics: Fork, Pin, Skewer, Mate-in-1, Mate-in-2, Back-rank – 1 shielded app – Full ELO tracking – Insights into what you solve and what you miss PRO UNLOCKS – All 52 advanced tactics.

Verdict

The call

Chess Shield's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
