Verdict

The call

The clearest difference is review sentiment: Flight Deck FMS at 100% against Retra's 15%. Flight Deck FMS also leads on ads (none vs shown). Retra's advantage is rating (4.8 vs 4.2) and ratings volume (3K vs 5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Retra sells 3 in-app purchases, starting at $6.99 per 7 days and Flight Deck FMS sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Retra holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Retra has 3K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 15% of Retra's written reviews are positive against 100% of Flight Deck FMS's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Retra ships an update every 4 days, Flight Deck FMS every 5 days. The most recent releases landed on October 28, 2026 and October 9, 2026 respectively.
