# Bluetooth for Arduino vs Uni Controller

The clearest difference is iOS requirement: Uni Controller at 13.0 against Bluetooth for Arduino's 18.5. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Bluetooth for Arduino sells 5 one-off in-app purchases and Uni Controller sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
