Verdict

The call

Push Ups Trainer Challenge and 100 Sit both sit at 4.7 stars, but that hides the real split: 87% of 100 Sit's written reviews are positive against 49% of Push Ups Trainer Challenge's. 100 Sit also leads on update cadence (every 10 days vs every 2 months). Push Ups Trainer Challenge's advantage is ads (none vs shown) and ratings volume (3.4K vs 131). On price, rating, in-app purchases and monetization model there is nothing between them.
