Verdict
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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
