# GymFit vs Interval Flow

The clearest difference is monetization model: GymFit at free with in-app purchases against Interval Flow's subscription. GymFit also leads on review sentiment (62% vs 48%). Interval Flow's advantage is ads (none vs shown) and ratings volume (168 vs 17). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. GymFit sells 12 in-app purchases, starting at $1.99 per 7 days 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.

On the App Store both sit at effectively the same score — 4.6 for GymFit against 4.7 for Interval Flow. That said, the two scores are not equally well evidenced: Interval Flow has 168 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 62% of GymFit's written reviews are positive against 48% of Interval Flow's.

GymFit ships an update every 11 days, Interval Flow fortnightly. The most recent releases landed on June 1, 2026 and September 5, 2026 respectively.
