Verdict
Mountainside Fitness App and Source Performance both sit at 4.9 stars, but that hides the real split: 100% of Source Performance's written reviews are positive against 56% of Mountainside Fitness App's. Mountainside Fitness App's advantage is ratings volume (9.3K vs 10) and update cadence (fortnightly vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.
