Verdict

The call

The clearest difference is ads: HIIT Dual Timer at none against UtraWatch's shown. HIIT Dual Timer also leads on update cadence (every 5 days vs every 6 weeks) and rating (3.0 vs 2.6). UtraWatch's advantage is ratings volume (221 vs 1) and review sentiment (13% vs 0%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

HIIT Dual Timer holds the better App Store score, 3.0 against 2.6. That said, the two scores are not equally well evidenced: UtraWatch has 221 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of HIIT Dual Timer's written reviews are positive against 13% of UtraWatch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HIIT Dual Timer ships an update every 5 days, UtraWatch every 6 weeks. The most recent releases landed on June 3, 2026 and August 18, 2026 respectively.
