Verdict

The call

The clearest difference is ratings volume: Muscle Booster Workout Tracker at 138K against TrainedByJP's 33. Muscle Booster Workout Tracker also leads on chart position (#61 vs unranked). TrainedByJP's advantage is review sentiment (59% vs 43%) and update cadence (every 6 days vs every 2 weeks). On price, rating, ads and in-app purchases there is nothing between them.
