Verdict
The clearest difference is rating: FlightLog App at 4.5 against FMS 737's 3.7. FlightLog App also leads on review sentiment (77% vs 50%) and update cadence (every 3 weeks vs every 5 months). FMS 737's advantage is in-app purchases (none vs 3) and iOS requirement (12.0 vs 16.6). On price, ads and device support there is nothing between them.
