About
A place to practice what you want to remember.
Chessalto is an independent chess training app for beginners and improving players who already know the rules. It combines guided tactics lessons, spaced repetition, opening practice and game review.
Training with a next step
A puzzle can show you what you missed. A training path gives you a way to work on it. Chessalto organizes tactical themes into lessons and practice, then schedules reviews across sessions.
The aim is to make regular chess practice easier to follow. Your Alto Score describes your progress within Chessalto; it does not replace an official or online playing rating.
