Verdict
The clearest difference is ads: Interval Timer at none against HIIT's shown. HIIT's advantage is ratings volume (31K vs 534) and review sentiment (91% vs 77%). On price, rating, update cadence and in-app purchases 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 4 in-app purchases, starting at $1.99 per month and HIIT sells 11 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Interval Timer against 4.8 for HIIT. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 534, so its average is the more settled of the two. Written reviews are what separate them: 77% of Interval Timer's written reviews are positive against 91% of HIIT's.
Interval Timer ships an update every 4 weeks, HIIT monthly. The most recent releases landed on September 17, 2026 and September 24, 2026 respectively.
