Verdict
The clearest difference is price: FlightLine at Free against iYield's $2.99. FlightLine also leads on ratings volume (10 vs 1) and iOS requirement (14.0 vs 16.1). iYield's advantage is update cadence (every 8 days vs every 5 weeks). On rating, ads, in-app purchases and device support there is nothing between them.
