Verdict

The call

The clearest difference is rating: Caliber at 4.8 against Air Workouts's 3.8. Caliber also leads on review sentiment (78% vs 50%) and ratings volume (6.1K vs 5). Air Workouts's advantage is update cadence (weekly vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.
