Verdict
The clearest difference is ads: Gymboss Interval Timer at none against Interval Timer's shown. Gymboss Interval Timer also leads on rating (4.7 vs 4.5). Interval Timer's advantage is review sentiment (69% vs 36%) and update cadence (every 9 days vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Gymboss Interval Timer sells 3 in-app purchases, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.
Gymboss Interval Timer holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 797, so its average is the more settled of the two. Written reviews complicate that: 69% of Interval Timer's written reviews are positive against 36% of Gymboss Interval 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, Gymboss Interval Timer every 5 weeks. Both last shipped on September 24, 2026.
