# i vs Interval Timer

i and Interval Timer both sit at 5.0 stars, but that hides the real split: 97% of Interval Timer's written reviews are positive against 43% of i's. Interval Timer also leads on ratings volume (379 vs 1) and device support (4 vs 2). i's advantage is update cadence (every 9 days vs monthly) and iOS requirement (13.6 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. i sells 1 one-off in-app purchase and Interval Timer sells 12 in-app purchases, starting at $2.09 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 — 5.0 for i against 4.9 for Interval Timer. That said, the two scores are not equally well evidenced: Interval Timer has 379 ratings behind it against 1, so its average is the more settled of the two.
