Verdict

The call

The clearest difference is rating: 21Moves | Cube Puzzle Solver at 4.7 against Finger Timer's 4.2. 21Moves | Cube Puzzle Solver also leads on update cadence (weekly vs every 16 months) and ratings volume (59K vs 345). Finger Timer's advantage is in-app purchases (none vs 11). On price, review sentiment, ads and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

21Moves | Cube Puzzle Solver holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: 21Moves | Cube Puzzle Solver has 59K ratings behind it against 345, so its average is the more settled of the two. Written reviews complicate that: 75% of Finger Timer'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.

UpkeepUpdate frequency

Finger Timer ships an update every 16 months, 21Moves | Cube Puzzle Solver weekly. The most recent releases landed on September 18, 2026 and September 24, 2026 respectively.
