Verdict

The call

The clearest difference is rating: Burnd at 5.0 against Interval Timer's 4.5. Burnd also leads on update cadence (every 4 days vs every 3 months). Interval Timer's advantage is ratings volume (534 vs 1) and review sentiment (21% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Burnd holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Interval Timer has 534 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 21% of Interval Timer's written reviews are positive against 0% of Burnd's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Interval Timer ships an update every 3 months, Burnd every 4 days. The most recent releases landed on September 1, 2026 and September 16, 2026 respectively.
