This is a great app. Really like the progress curve. So many interesting positions, and the answers are stretching my chess experience, judgement and imagination. The puzzles are not restricted to "mate in x moves" but often look for advantage, in interesting ways. Like that it evolves with you. Hadn't realised it was based on Stockfish! Bonus! Only wish I'd been taking notes from the beginning, and wish I could start the series again. Pls: Would like to be able to play them all back. Thank you

Original review, 2024 - Very happy with the puzzle selection, analysis feature, and accuracy. 1/30/26 - dropped from 5 to 4 stars. I found winning solutions to 352 and 353 which the app failed to recognize. Also, no method to report problems such as this from the app. 9/1/26 - I got tired of Stockfish showing a 'Winning' assessment of my move. While it might not be as elegant as the given solution, it wins. And that's the objective. I deleted the app.

It's simple, minimalist, and has everything a beginner may need. I've watched myself grow from a shakey 1100 to a 1700s, at present. Quick & obvious tips: if you feel like a puzzle ended too quickly, just go back and turn on analysis to see the rest. If you particularly feel like practicing a puzzle, you can play the computer from that point on. You can also revisit old levels by swiping on the analysis board.
