# Interval Timer vs Interval Flow

The clearest difference is review sentiment: Interval Timer at 100% against Interval Flow's 48%. Interval Timer also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.7). Interval Flow's advantage is ratings volume (168 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 3 in-app purchases, starting at $1.99 per month and Interval Flow sells 10 in-app purchases, starting at $4.99 per 3 months. Whichever you choose, the download price is not the number that matters.

Interval Timer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Interval Flow has 168 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of Interval Timer's written reviews are positive against 48% of Interval Flow's.

Interval Timer ships an update every 3 weeks, Interval Flow fortnightly. The most recent releases landed on September 23, 2026 and October 2, 2026 respectively.
