# Seconds Interval Timer vs Burnd

The clearest difference is review sentiment: Seconds Interval Timer at 75% against Burnd's 0%. Seconds Interval Timer also leads on ratings volume (24K vs 1) and iOS requirement (18.0 vs 26.0). Burnd's advantage is update cadence (every 4 days vs monthly) and rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Seconds Interval Timer sells 1 one-off in-app purchase and Burnd sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Burnd holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Seconds Interval Timer has 24K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Seconds 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.

Seconds Interval Timer ships an update monthly, Burnd every 4 days. The most recent releases landed on September 26, 2026 and September 16, 2026 respectively.
