Verdict
The clearest difference is update cadence: Fastastic at daily against Withings's fortnightly. Fastastic also leads on iOS requirement (16.4 vs 18.0). Withings's advantage is chart position (#54 vs unranked) and device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
