Verdict
The clearest difference is rating: Interval Timer at 4.5 against Custom Workout Timer's 3.7. Interval Timer also leads on update cadence (every 9 days vs every 6 months) and ratings volume (19K vs 6). Custom Workout Timer's advantage is ads (none vs shown) and review sentiment (88% vs 69%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Custom Workout Timer sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Interval Timer holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 69% of Interval Timer's written reviews are positive against 88% of Custom Workout Timer's, so the app with the better star average is not the one people write more warmly about.
Interval Timer ships an update every 9 days, Custom Workout Timer every 6 months. The most recent releases landed on September 24, 2026 and June 10, 2026 respectively.
