This app was exactly what I was looking for and only 2.2MB! Download and opened it and everything seems to work, and as far as people who say the save button is gone, just open the app in portrait mode (Vertical) and the save button will be there.
The problem: Once you click the save button the app freezes. Nothing happens and you have to shut down the app. So there is no point in owning this app if you are unable to save!
