Verdict
The clearest difference is ads: Fasting Timer at none against FastFlow's shown. Fasting Timer also leads on update cadence (fortnightly vs every 4 months). FastFlow's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.6). On price and in-app purchases there is nothing between them.
