# iPreFlight3 vs Avianis

The clearest difference is rating: iPreFlight3 at 3.1 against Avianis's 2.4. Avianis's advantage is update cadence (fortnightly vs every 6 weeks) and device support (3 vs 1). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

iPreFlight3 holds the better App Store score, 3.1 against 2.4. Both are backed by a comparable volume of ratings — 55 and 25 respectively. Written reviews complicate that: 5% of iPreFlight3's written reviews are positive against 11% of Avianis's, so the app with the better star average is not the one people write more warmly about.

iPreFlight3 ships an update every 6 weeks, Avianis fortnightly. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
