# Interval Timer vs Group Fitness Class Timer

The clearest difference is rating: Group Fitness Class Timer at 5.0 against Interval Timer's 4.5. Group Fitness Class Timer also leads on ads (none vs shown) and update cadence (every 2 days vs every 9 days). Interval Timer's advantage is ratings volume (19K vs 2) and iOS requirement (13.0 vs 26.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Group Fitness Class Timer sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
