Verdict

The call

The clearest difference is price: Cockpit App Systems at Free against FAA ATP Written Test Prep's $79.99. Cockpit App Systems also leads on rating (4.8 vs 4.5) and ratings volume (496 vs 19). FAA ATP Written Test Prep's advantage is update cadence (monthly vs every 2 months) and review sentiment (74% vs 63%). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Cockpit App Systems holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Cockpit App Systems has 496 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 74% of FAA ATP Written Test Prep's written reviews are positive against 63% of Cockpit App Systems's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FAA ATP Written Test Prep ships an update monthly, Cockpit App Systems every 2 months. The most recent releases landed on November 1, 2026 and October 26, 2026 respectively.
