# FlightLine vs iYield

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.

On the App Store both sit at effectively the same score — 5.0 for FlightLine against 5.0 for iYield. That said, the two scores are not equally well evidenced: FlightLine has 10 ratings behind it against 1, so its average is the more settled of the two.
