Openings Mastermind holds the better App Store score, 4.3 against 3.9. Both are backed by a comparable volume of ratings — 17 and 6 respectively. Written reviews complicate that: 57% of Chess Openings Trainer's written reviews are positive against 50% of Openings Mastermind's, so the app with the better star average is not the one people write more warmly about.
