The short verdict

ChessFlare is a broad training app at a low price: a repertoire editor and opening trainer, game sync from chess.com and Lichess, game summaries, blunder review aimed at recurring errors, weak-spot puzzles and an AI coach. It does review your games and it does use spaced repetition. The differences are narrower. Rukh uses your clock, opens a lesson only after the same miss repeats 3 times in your real games, and counts it mastered only when you play it in 4 of your next 5 real chances. If you want openings, tactics and review in one cheap app, ChessFlare is built for that. If you want a coach that proves a habit is fixed in your real games, Rukh is built for that.

ChessFlare is for

Self-improvers from beginner to club level who want repertoire study, puzzles, game review and a daily routine in one inexpensive app, on web, iOS and Android.

Rukh is for

Players who already play openings, keep repeating the same misses, and want a coach that works from their own games and clock and checks the fix in real play.
