Verdict

The call

The clearest difference is in-app purchases: FitCat at none against FastingCat's 10. FitCat also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). FastingCat's advantage is update cadence (every 6 days vs fortnightly). On price and ads there is nothing between them.
