Verdict

The call

The clearest difference is rating: Boxing Timer Pro Round Timer at 4.9 against Modern Interval Workout Timer's 3.0. Boxing Timer Pro Round Timer also leads on ratings volume (6.7K vs 1). Modern Interval Workout Timer's advantage is review sentiment (100% vs 61%) and update cadence (every 4 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Boxing Timer Pro Round Timer holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Boxing Timer Pro Round Timer has 6.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 61% of Boxing Timer Pro Round Timer's written reviews are positive against 100% of Modern Interval Workout Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Boxing Timer Pro Round Timer ships an update monthly, Modern Interval Workout Timer every 4 days. The most recent releases landed on September 25, 2026 and September 3, 2026 respectively.
