# Workout Timer vs Interval Flow

The clearest difference is monetization model: Workout Timer at free with in-app purchases against Interval Flow's subscription. Workout Timer also leads on review sentiment (65% vs 48%) and iOS requirement (12.0 vs 18.6). Interval Flow's advantage is rating (4.7 vs 4.5) and ratings volume (168 vs 15). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Workout Timer sells 1 one-off in-app purchase 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 Flow has 168 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 65% of Workout 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.

Workout Timer ships an update every 3 weeks, Interval Flow fortnightly. The most recent releases landed on September 26, 2026 and September 5, 2026 respectively.
