# 21Moves | Cube Puzzle Solver vs Selector

The clearest difference is in-app purchases: Selector at none against 21Moves | Cube Puzzle Solver's 10. Selector also leads on review sentiment (100% vs 70%). 21Moves | Cube Puzzle Solver's advantage is ads (none vs shown) and ratings volume (60K vs 2). On price and device support there is nothing between them.

Both are free to download. 21Moves | Cube Puzzle Solver sells 9 in-app purchases, starting at $1.99 per month. Selector asks for nothing beyond the download.

21Moves | Cube Puzzle Solver holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: 21Moves | Cube Puzzle Solver has 60K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 70% of 21Moves | Cube Puzzle Solver's written reviews are positive against 100% of Selector's, so the app with the better star average is not the one people write more warmly about.
