# My Interval Timer vs Optimize.AI

The clearest difference is review sentiment: Optimize.AI at 96% against My Interval Timer's 67%. Optimize.AI also leads on update cadence (every 3 months vs every 8 months). My Interval Timer's advantage is rating (4.7 vs 4.4). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. My Interval Timer sells 7 in-app purchases, starting at $2.99 per 7 days and Optimize.AI sells 2 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.

My Interval Timer holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 51 and 97 respectively. Written reviews complicate that: 67% of My Interval Timer's written reviews are positive against 96% of Optimize.AI's, so the app with the better star average is not the one people write more warmly about.

My Interval Timer ships an update every 8 months, Optimize.AI every 3 months. The most recent releases landed on September 8, 2026 and August 11, 2026 respectively.
