# Flight Computer Sim vs Zulu Time Now

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.

Both are free to download. Zulu Time Now sells 1 one-off in-app purchase. Flight Computer Sim asks for nothing beyond the download.

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.

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.
