Verdict

The call

The clearest difference is review sentiment: Supplement Stack at 100% against iFIT Personal Trainer's 57%. Supplement Stack also leads on rating (5.0 vs 4.7) and update cadence (every 4 days vs fortnightly). iFIT Personal Trainer's advantage is ratings volume (1.6K vs 3) and chart position (#75 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
