A chess tactics trainer for Mac, with no subscription
Train pattern recognition on over six million Lichess puzzles, tagged by theme, with difficulty that follows your estimated rating and missed puzzles that come back until they stick.
Puzzles that fit your level
Puzzles come from the open Lichess puzzle database, imported once from the app so they are available offline. Difficulty follows your estimated rating, and you can train the themes you want to improve.
Review what you miss
Puzzles you get wrong return on a review schedule, and your home screen shows what is due today across tactics, Woodpecker sets, openings, endgames and your own middlegame mistakes.
Prefer speed? Rush runs are score-attack puzzle sessions that sharpen how quickly you see a tactic under pressure, with your results tracked alongside everything else.
See your weak spots
Stats include an activity heatmap and a breakdown by theme, so the next session can go straight at what you are actually bad at.
