Verdict
The clearest difference is in-app purchases: RepPrep AI at none against CupCalc's 2. RepPrep AI also leads on update cadence (weekly vs fortnightly) and ratings volume (5 vs 1). CupCalc's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, rating and ads there is nothing between them.
