Can I use unTill Air POS app in the desktop version (e.g. Windows PC)?

No, unTill Air POS app is not compatible with desktops or laptops, meaning you can't run the POS on them. unTill Air is a mobile app that works with tablets and smartphones (iPhones, iPads, Android smartphones and tablets, Sunmi devices).

You can use your desktop or laptop to manage your products and location in the Back Office at air.untill.com, but you can't launch the POS on them.
