# RunGap vs Polar Flow

RunGap and Polar Flow both sit at 4.8 stars, but that hides the real split: 77% of RunGap's written reviews are positive against 50% of Polar Flow's. RunGap also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (15.6 vs 17.0). Polar Flow's advantage is ratings volume (50K vs 5.9K). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. RunGap sells 4 in-app purchases, starting at $4.99 per 3 months and Polar Flow sells 1 in-app purchase, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for RunGap against 4.6 for Polar Flow. That said, the two scores are not equally well evidenced: Polar Flow has 50K ratings behind it against 5.9K, so its average is the more settled of the two. Written reviews are what separate them: 77% of RunGap's written reviews are positive against 50% of Polar Flow's.

RunGap ships an update every 2 weeks, Polar Flow monthly. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
