# Custom Workout Timer vs Interval Timer

The clearest difference is rating: Interval Timer at 4.9 against Custom Workout Timer's 3.7. Interval Timer also leads on update cadence (monthly vs every 6 months) and ratings volume (379 vs 6). Custom Workout Timer's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Custom Workout Timer sells 2 one-off in-app purchases and Interval Timer sells 12 in-app purchases, starting at $2.09 per month. Whichever you choose, the download price is not the number that matters.

Interval Timer holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: Interval Timer has 379 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 88% of Custom Workout Timer's written reviews are positive against 97% of Interval Timer's.

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