Verdict
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.
