Verdict
The clearest difference is in-app purchases: Birch Fit at none against Fasting Tracker's 4. Birch Fit also leads on ads (none vs shown) and iOS requirement (15.6 vs 17.0). Fasting Tracker's advantage is update cadence (every 3 days vs every 4 weeks). On price and device support there is nothing between them.
