What's New in PGN Trainer
1.0.11
November 5, 2026
New: build your repertoire from your games. Enter your Lichess or Chess.com username and the app turns the openings you play in your rated games into a White and a Black repertoire, ready to train. Where your move leaves the opening book and your own studies, it counts as a mistake and the good moves are taught instead; those lines come up first in training. Find it on the Library card, under + → Build from my games…, or in Game Review → Update my repertoire from my games. Run it again any time to update your repertoire; the moves you added yourself are kept. At the end of a line: when your studies or the opening book go on from the position, the app offers to continue in that study or to add the opening book's moves to your repertoire. Updated opening book: more openings and positions, with up-to-date names on your studies. Import: overwriting a study keeps the training progress of the lines that stay. Fixes: memberships stay active while the App Store answers, and you can try again if they don't load.
