# FlightDuty vs Aviation Dictionary

The clearest difference is price: Aviation Dictionary at Free against FlightDuty's $3.99. Aviation Dictionary also leads on rating (4.3 vs 3.8) and ratings volume (18 vs 5). FlightDuty's advantage is review sentiment (75% vs 40%) and in-app purchases (none vs 3). On device support there is nothing between them.

Aviation Dictionary is free to download; FlightDuty costs $3.99 up front. Aviation Dictionary sells 3 in-app purchases, starting at $0.99 per 7 days. FlightDuty asks for nothing beyond the download.

Aviation Dictionary holds the better App Store score, 4.3 against 3.8. Both are backed by a comparable volume of ratings — 5 and 18 respectively. Written reviews complicate that: 75% of FlightDuty's written reviews are positive against 40% of Aviation Dictionary's, so the app with the better star average is not the one people write more warmly about.

FlightDuty ships an update monthly, Aviation Dictionary every 4 months. The most recent releases landed on October 2, 2026 and October 5, 2026 respectively.
