Verdict

The call

The clearest difference is rating: Interval Timer ++ at 4.8 against Custom Workout Timer's 3.7. Interval Timer ++ also leads on update cadence (every 3 weeks vs every 6 months) and ratings volume (15K vs 6). Custom Workout Timer's advantage is ads (none vs shown) and review sentiment (88% vs 78%). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Interval Timer ++ holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Interval Timer ++ has 15K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 88% of Custom Workout Timer's written reviews are positive against 78% of Interval Timer ++'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Custom Workout Timer ships an update every 6 months, Interval Timer ++ every 3 weeks. The most recent releases landed on June 10, 2026 and September 30, 2026 respectively.
