Want to know how much is left to end lesson? The app does it for you :)
When you first start login settings, and specify the time the end of the lesson, then you will always know the time remaining until the end of the lessons :)
The maximum number of lessons at this moment is limited to 7, but this is only Beta;)
At the moment the application is in the status of Beta, this is it does not have a beautiful design. However, I am happy to consider your suggestions to my mail :)
