# Longitude vs Binary Clock

The clearest difference is iOS requirement: Longitude at 17.0 against Binary Clock's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Longitude sells 3 in-app purchases, starting at $2.99 per month and Binary Clock sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
