# Ukulele Tuner vs 21Moves | Cube Puzzle Solver

The clearest difference is rating: 21Moves | Cube Puzzle Solver at 4.7 against Ukulele Tuner's 4.0. 21Moves | Cube Puzzle Solver also leads on ratings volume (60K vs 1). Ukulele Tuner's advantage is in-app purchases (none vs 11) and review sentiment (100% vs 70%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. 21Moves | Cube Puzzle Solver sells 10 in-app purchases, starting at $1.99 per month. Ukulele Tuner asks for nothing beyond the download.

21Moves | Cube Puzzle Solver holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: 21Moves | Cube Puzzle Solver has 60K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Ukulele Tuner's written reviews are positive against 70% of 21Moves | Cube Puzzle Solver's, so the app with the better star average is not the one people write more warmly about.
