Learn from your own blunders.

Blunderloop finds the mistakes in your Lichess and Chess.com games and turns them into positions you practise with spaced repetition, until you find the right move.

For iPhone. Coming soon to the App Store.

• Your games, not random puzzles

  Enter your Lichess or Chess.com username. Blunderloop loads your public games and picks the moments where you went wrong.

• Analysis on your iPhone

  The built-in Blunderloop Engine analyses your games on the device. No account, no server of ours, no tracking.

• Spaced repetition

  Each position comes back just before you would forget it. A few minutes a day keep your streak and your memory alive.

• Widgets

  See what is due on your Home Screen and Lock Screen, or solve a position right in the large widget.

Price

Free to download and to try for 30 days. After that, a one-time purchase unlocks new positions. Reviewing the positions you already have stays free.
