Verdict
The clearest difference is rating: SITC App at 5.0 against Fitbit Ace's 4.1. SITC App also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 17.0). Fitbit Ace's advantage is ratings volume (216 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
