# TrainedByJP vs Muscle Booster Workout Tracker

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 (#66 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.

Both are free to download. TrainedByJP sells 6 in-app purchases, starting at $9.49 per month and Muscle Booster Workout Tracker sells 16 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

TrainedByJP holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Muscle Booster Workout Tracker has 138K ratings behind it against 33, so its average is the more settled of the two. Written reviews point the same way: 59% of TrainedByJP's written reviews are positive against 43% of Muscle Booster Workout Tracker's.
