Verdict

The call

The clearest difference is in-app purchases: Session at none against RoundFlow's 3. Session also leads on ratings volume (8 vs 1) and iOS requirement (15.1 vs 17.0). RoundFlow's advantage is update cadence (weekly vs every 2 months). On price, rating, ads and device support there is nothing between them.
