# Instrument Test Prep Airplane vs Flight Test X20

The clearest difference is price: Flight Test X20 at Free against Instrument Test Prep Airplane's $4.99. Flight Test X20 also leads on rating (3.9 vs 3.3) and update cadence (every 5 weeks vs every 4 months). Instrument Test Prep Airplane's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 14.0). On review sentiment, ads and in-app purchases there is nothing between them.

Flight Test X20 is free to download; Instrument Test Prep Airplane costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Flight Test X20 holds the better App Store score, 3.9 against 3.3. That said, the two scores are not equally well evidenced: Flight Test X20 has 96 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Instrument Test Prep Airplane's written reviews are positive against 60% of Flight Test X20's, so the app with the better star average is not the one people write more warmly about.

Instrument Test Prep Airplane ships an update every 4 months, Flight Test X20 every 5 weeks. Both last shipped on October 24, 2026.
