Change: For an update, the app checks the license with the app and the last shop opens all the time. It is very painful and in addition, the app stops working without connection to the net :( I withdraw my previous 3 stars évaluataion render unnecessary because it applied to me. Before, I used the application of standard Google calendar. but I find it very well too successful for its integration stains module (to install and more) and the widget that displays a clear way all one needs to know about his appointment.
