Currently, we do not have Appointy mobile app for your clients.
We have a mobile version of Appointy. It has been tested on iPhone, Android, iPad and other similar devices.
Your client just needs to open your unique Appointy URL on their mobile phone. Appointy will automatically detect their hardware and render it accordingly.
For example, if your username is “lalunasalon”, then opening http://lalunasalon.appointy.com on their PC or Mac will open the classic version, while on iPhone or other mobile devices, it will open the mobile version of Appointy.
On mobile devices, they can add a shortcut to the home screen to open it like a Mobile App.
