Trade screen time for chess time.
Choose the apps you want to use less. CHESS/BLOCK pauses them on your schedule, then turns the urge to scroll into a short chess lesson or puzzle matched to your level.
Practice instead
Learn chess from the beginning or solve puzzles matched to your approximate rating and training focus.
Earn your time
Each completed lesson or puzzle adds personalized time to your on-device bank for the apps you selected.
A better interruption
Make every unlock count.
CHESS/BLOCK replaces a reflexive app open with focused chess practice. Beginners build skills one lesson at a time. Regular players get a mix of positions at their level. Either way, practice earns the time you choose to spend.
Meet you at your level
Start with guided lessons or set an approximate rating and focus for adaptive puzzle practice.
Keep the reward personal
Your plan determines how much time each completed lesson or puzzle earns, up to the app’s reward limit.
Keep your focus private
Your app selections, earned-time balance, and progress stay on your device. A Lichess connection is optional.
