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.
