# Aviation Exam vs Part66

The clearest difference is rating: Aviation Exam at 4.8 against Part66's 4.5. Aviation Exam also leads on ratings volume (495 vs 10) and review sentiment (79% vs 60%). Part66's advantage is iOS requirement (10.3 vs 12.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Aviation Exam sells 30 one-off in-app purchases and Part66 sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Aviation Exam holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Aviation Exam has 495 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 79% of Aviation Exam's written reviews are positive against 60% of Part66's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
