# Interval Timer vs Interval Flow

The clearest difference is monetization model: Interval Timer at free with in-app purchases against Interval Flow's subscription. Interval Timer also leads on ratings volume (19K vs 168) and review sentiment (69% vs 48%). Interval Flow's advantage is ads (none vs shown) and rating (4.7 vs 4.5). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 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 Flow holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 168, so its average is the more settled of the two. Written reviews complicate that: 69% of Interval Timer's written reviews are positive against 48% of Interval Flow's, so the app with the better star average is not the one people write more warmly about.

Interval Timer ships an update every 9 days, Interval Flow fortnightly. The most recent releases landed on September 24, 2026 and September 5, 2026 respectively.
