Verdict

The call

The clearest difference is rating: Instrument Test Prep at 4.9 against iCESSNA Aircraft Apps's 4.4. Instrument Test Prep also leads on ratings volume (156 vs 7). iCESSNA Aircraft Apps's advantage is review sentiment (100% vs 88%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Instrument Test Prep sells 4 one-off in-app purchases and iCESSNA Aircraft Apps sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Instrument Test Prep holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Instrument Test Prep has 156 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 88% of Instrument Test Prep's written reviews are positive against 100% of iCESSNA Aircraft Apps's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Instrument Test Prep ships an update fortnightly, iCESSNA Aircraft Apps every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
