Not Necessary
I personally could really do without this app. When I redid my phone recently and found out the calendar was tough to figure out. When I looked to see there was a update for the problem. Thank you, I could do without it but I hope I never have to. It is just another thing that helps make me a master of my bills.
Can I suggest a dropbox backup?
Wonderful app regardless.
