# Interval Timer vs Cross Fit Zone Training

The clearest difference is ads: Cross Fit Zone Training at none against Interval Timer's shown. Cross Fit Zone Training also leads on review sentiment (80% vs 69%). Interval Timer's advantage is ratings volume (19K vs 24) and device support (4 vs 2). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Cross Fit Zone Training sells 6 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Interval Timer against 4.6 for Cross Fit Zone Training. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 24, so its average is the more settled of the two. Written reviews are what separate them: 69% of Interval Timer's written reviews are positive against 80% of Cross Fit Zone Training's.

Interval Timer ships an update every 9 days, Cross Fit Zone Training every 10 days. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
