Build a repertoire, drill the endgames that decide games, and let spaced repetition keep both fresh. Then analyse a real game and watch the report trace it back to your own lines.
Three parts of the same habit. The first two schedule themselves; the third tells you whether it is working.
Build an opening tree or paste a PGN, then let spaced repetition ask you for your own moves. Learn, practise, review and drill your weak spots, every move on its own clock.
30 famous and essential positions in six categories. Study the annotated technique, then play it out against Stockfish until it actually holds.
Paste a game or pull it straight from Lichess or Chess.com. Every move is graded and explained in a sentence, with the better line there to play through.
A class on every move is the easy half. The report also says what the move did to the position, and gives you the line to play instead.

Progress is tracked on individual moves, not whole lines, so one shaky move doesn't drag a line you already know down with it.
Paste PGN and every variation, comment and arrow annotation comes across intact, nested lines included.
The whole app is free. A couple of the heavier things are Pro, and there is no checkout: you email an administrator and they switch it on.
Everything you need to train.
The engine-heavy half.
