You choose what the next Run should train.

Custom Runs
Pick puzzle themes, pace, duration, and starting difficulty yourself. You stay in control of what each Run practices.
Review and Replay

Works fully offline
Puzzle Sprints, Custom Runs, Review, and optional analysis all work without an internet connection. No ads or Chessticize account required.
Also on iPad. Keep progress in sync across your Apple devices with optional private iCloud Sync.
Private by design
Your puzzle practice is not our dataset.
Chessticize has no ads, analytics, tracking, or Chessticize account. Puzzle practice and optional analysis run on your device.
Progress starts on your device. Private iCloud Sync can merge progress across your Apple devices and can be turned off; Chessticize does not operate a sync server or receive that data.
