# i vs Interval Timer

The clearest difference is monetization model: i at free with in-app purchases against Interval Timer's subscription. i also leads on rating (5.0 vs 4.7) and update cadence (every 9 days vs every 4 weeks). Interval Timer's advantage is ads (none vs shown) and ratings volume (3.5K vs 1). On price, in-app purchases and device support 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 $1.99 per month. Whichever you choose, the download price is not the number that matters.

i holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Interval Timer has 3.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of i's written reviews are positive against 67% of Interval Timer's, so the app with the better star average is not the one people write more warmly about.

i ships an update every 9 days, Interval Timer every 4 weeks. The most recent releases landed on August 20, 2026 and September 25, 2026 respectively.
