Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

Aviation Exam holds the better App Store score, 4.8 against 4.5.

UpkeepUpdate frequency

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