# Four vs air

The clearest difference is price: Four at Free against air's $4.99. Four also leads on review sentiment (100% vs 89%). air's advantage is rating (4.5 vs 1.0) and ratings volume (20 vs 1). On in-app purchases there is nothing between them.

Four is free to download; air costs $4.99 up front. Four sells 2 one-off in-app purchases and air sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

air holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: air has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Four's written reviews are positive against 89% of air's, so the app with the better star average is not the one people write more warmly about.
