# IFR Flight Trainer Simulator vs ATSim

The clearest difference is in-app purchases: ATSim at none against IFR Flight Trainer Simulator's 2. ATSim also leads on iOS requirement (12.1 vs 18.6). IFR Flight Trainer Simulator's advantage is review sentiment (82% vs 63%) and ratings volume (76 vs 15). On price, rating, ads and device support there is nothing between them.

Both are free to download. IFR Flight Trainer Simulator sells 2 one-off in-app purchases. ATSim asks for nothing beyond the download.

ATSim holds the better App Store score, 4.1 against 3.9. That said, the two scores are not equally well evidenced: IFR Flight Trainer Simulator has 76 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 82% of IFR Flight Trainer Simulator'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.
