Verdict
The clearest difference is ratings volume: Gym Rank at 171 against StrengthIn's 1. Gym Rank also leads on update cadence (every 2 weeks vs every 3 weeks) and iOS requirement (15.0 vs 17.6). StrengthIn's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
