Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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