# World Clock Pro vs FlightDeck EFB

The clearest difference is in-app purchases: FlightDeck EFB at none against World Clock Pro's 6. FlightDeck EFB also leads on review sentiment (98% vs 77%). World Clock Pro's advantage is ratings volume (1.4K vs 28) and iOS requirement (13.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. World Clock Pro sells 5 in-app purchases, starting at $1.99 per month. FlightDeck EFB asks for nothing beyond the download.

FlightDeck EFB holds the better App Store score, 4.9 against 4.8. That said, the two scores are not equally well evidenced: World Clock Pro has 1.4K ratings behind it against 28, so its average is the more settled of the two.
