Verdict
The clearest difference is rating: Gym Rank at 4.8 against JumpBoost's 4.2. Gym Rank also leads on review sentiment (84% vs 73%) and iOS requirement (15.0 vs 17.0). JumpBoost's advantage is monetization model (free vs free with in-app purchases). On price, ratings volume, update cadence and ads there is nothing between them.
