Verdict

The call

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.
