Verdict
The clearest difference is in-app purchases: KetoBM at none against Fasting Tracker's 4. KetoBM also leads on ads (none vs shown) and rating (5.0 vs 4.7). Fasting Tracker's advantage is ratings volume (430 vs 2) and update cadence (every 3 days vs fortnightly). On price and device support there is nothing between them.
