# Flight IFR Nav Trainer vs ATSim

The clearest difference is in-app purchases: ATSim at none against Flight IFR Nav Trainer's 1. ATSim also leads on review sentiment (63% vs 48%) and iOS requirement (12.1 vs 16.0). Flight IFR Nav Trainer's advantage is rating (4.6 vs 4.1) and ratings volume (302 vs 15). On price, ads and device support there is nothing between them.

Both are free to download. Flight IFR Nav Trainer sells 1 one-off in-app purchase. ATSim asks for nothing beyond the download.

Flight IFR Nav Trainer holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Flight IFR Nav Trainer has 302 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 48% of Flight IFR Nav Trainer's written reviews are positive against 63% of ATSim's, so the app with the better star average is not the one people write more warmly about.
