Verdict
The clearest difference is ads: GAC KEY WATCH at none against Da Fit's shown. GAC KEY WATCH also leads on rating (5.0 vs 4.7) and monetization model (free vs ad-supported). Da Fit's advantage is ratings volume (229K vs 1) and update cadence (fortnightly vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
