Compared to version 1 - poor. Allows for editing one entry of (for example) a weekly appointment, but rather than edit the one instance (as you think you are doing) it creates a new one, so you have a double entry, the original which you can't delete, even after synching. If you've set weekly appointments and one is cancelled, you should be able to edit that one instance without creating a duplicate. I've had this installed for some time now, thinking that the developers would resolve these problems, but although the app has regular 'updates', nothing has changed. Drag and drop defaults to copy, imo should be 'move' by default. If you change an appointment it changes, not duplicates. Also the interface and look (big text and colours) looks like a children's calender, while the original version actually looked quite professional.
