Verdict
The clearest difference is price: Interval Timer at Free against HIIT (Watch) Timer's $3.99. Interval Timer also leads on update cadence (every 9 days vs every 2 months) and ratings volume (19K vs 12). HIIT (Watch) Timer's advantage is in-app purchases (none vs 8) and ads (none vs shown). On device support there is nothing between them.

Interval Timer is free to download; HIIT (Watch) Timer costs $3.99 up front. Interval Timer sells 6 in-app purchases, starting at $0.99 per month. HIIT (Watch) Timer asks for nothing beyond the download.
Interval Timer holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 69% of Interval Timer's written reviews are positive against 80% of HIIT (Watch) 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, HIIT (Watch) Timer every 2 months. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
