# Interval Timer vs BJJ Stopwatch

The clearest difference is ads: BJJ Stopwatch at none against Interval Timer's shown. BJJ Stopwatch also leads on monetization model (free vs free with in-app purchases) and update cadence (weekly vs monthly). Interval Timer's advantage is ratings volume (392 vs 1) and device support (4 vs 2). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 10 in-app purchases, starting at $2.09 per month and BJJ Stopwatch sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Interval Timer against 5.0 for BJJ Stopwatch. That said, the two scores are not equally well evidenced: Interval Timer has 392 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 97% of Interval Timer's written reviews are positive against 100% of BJJ Stopwatch's.

Interval Timer ships an update monthly, BJJ Stopwatch weekly. The most recent releases landed on November 12, 2026 and November 4, 2026 respectively.
