It is not super intuitive but it works and does what I was looking for in an app. It lets you set up and then automatically rotates it for you. Wish there was a notification system to add reminders or integrate with your google calendar (as future suggestions) but it is the bare of what I was looking for and I am grateful to find it.
While this seemed useful, a lot of planning and input would need to be put into it. It is easier for me to use a notebook or spreadsheet on the computer. However for with more time, the app is well put together. The ultimate fhe app would be one with already put together lessons and you put your family names in the list and the app do does the rest.
