Verdict

The call

The clearest difference is in-app purchases: Best Interval Timer at none against Round Timer's 1. Best Interval Timer also leads on review sentiment (89% vs 67%) and ratings volume (81 vs 14). Round Timer's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 12 months). On price, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Round Timer holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Best Interval Timer has 81 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 89% of Best Interval Timer's written reviews are positive against 67% of Round Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Best Interval Timer ships an update every 12 months, Round Timer every 2 weeks. The most recent releases landed on October 2, 2026 and September 20, 2026 respectively.
