# Boxing Interval Timer vs MMA Library

The clearest difference is rating: Boxing Interval Timer at 4.8 against MMA Library's 4.0. Boxing Interval Timer also leads on ratings volume (13K vs 1). MMA Library's advantage is review sentiment (100% vs 59%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Boxing Interval Timer sells 1 one-off in-app purchase and MMA Library sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Boxing Interval Timer holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Boxing Interval Timer has 13K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 59% of Boxing Interval Timer's written reviews are positive against 100% of MMA Library's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 24, 2026 and June 7, 2026 respectively.
