Verdict

The call

The clearest difference is in-app purchases: The One Rep Max at none against Ultimate Trainer's 3. The One Rep Max also leads on device support (3 vs 1) and iOS requirement (9.0 vs 17.2). Ultimate Trainer's advantage is update cadence (every 2 days vs every 10 days) and ratings volume (10 vs 1). On price, rating, review sentiment and ads there is nothing between them.
