Verdict

The call

The clearest difference is review sentiment: Interval Timer at 91% against HIIT (US)'s 50%. Interval Timer also leads on ads (none vs shown) and update cadence (every 2 days vs every 4 months). HIIT (US)'s advantage is rating (5.0 vs 4.8) and device support (4 vs 2). On price, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

HIIT (US) holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Interval Timer has 77 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of HIIT (US)'s written reviews are positive against 91% of Interval Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HIIT (US) ships an update every 4 months, Interval Timer every 2 days. The most recent releases landed on October 4, 2026 and October 12, 2026 respectively.
