# Seconds Interval Timer vs Custom Workout Timer

The clearest difference is rating: Seconds Interval Timer at 4.7 against Custom Workout Timer's 3.7. Seconds Interval Timer also leads on update cadence (monthly vs every 6 months) and ratings volume (24K vs 6). Custom Workout Timer's advantage is review sentiment (88% vs 75%) and iOS requirement (15.6 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Seconds Interval Timer sells 1 one-off in-app purchase and Custom Workout Timer sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Seconds Interval Timer holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Seconds Interval Timer has 24K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of Seconds 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.

Seconds Interval Timer ships an update monthly, Custom Workout Timer every 6 months. The most recent releases landed on September 24, 2026 and June 10, 2026 respectively.
