Verdict

The call

The clearest difference is in-app purchases: Flight Computer Sim at none against Zulu Time Now's 1. Flight Computer Sim also leads on review sentiment (88% vs 66%) and iOS requirement (7.0 vs 16.0). Zulu Time Now's advantage is update cadence (monthly vs every 6 months) and ratings volume (852 vs 29). On price, rating, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Zulu Time Now holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Zulu Time Now has 852 ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 88% of Flight Computer Sim's written reviews are positive against 66% of Zulu Time Now's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flight Computer Sim ships an update every 6 months, Zulu Time Now monthly. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
