# Chess Openings vs Openings Mastermind

The clearest difference is rating: Openings Mastermind at 4.3 against Chess Openings's 3.2. Openings Mastermind also leads on in-app purchases (none vs 3) and ads (none vs shown). Chess Openings's advantage is review sentiment (60% vs 50%) and iOS requirement (15.0 vs 18.6). On price, ratings volume and device support there is nothing between them.

Both are free to download. Chess Openings sells 3 one-off in-app purchases. Openings Mastermind asks for nothing beyond the download.

Openings Mastermind holds the better App Store score, 4.3 against 3.2. Both are backed by a comparable volume of ratings — 6 and 6 respectively. Written reviews complicate that: 60% of Chess Openings'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.
