Hello and congratulations for this excellent app.
I am a user of the lite version for months and as It works perfectly, I decided to upgrade to the full version (basic).
In the meanwhile I gave a try to a new similar app, Gootasks and it wiped 3 out of 7 lists! This app is a real scam (the 1st day collected more than 800 positive comments(!!!) in the french AppStore, certainly written by the developer) and completely useless in the free version.
My problem is that I am always afraid that something can happen and lose my tasks. I experimented this loss twice in other servers and programs of ToDos.
What is the solution to backup all my lists and their contents, so I can retrieve them if something goes wrong?
Of course I can email the lists, but it's not the solution as the mail doesn't include their contents.
I think of purchasing the full version but not to upgrade the lite version, so I can keep both versions on my iPhone. If something goes wrong I could synchronize with the lite version and use it as a backup.
What is your opinion? Can this turnaround work or do I have to try another process?
Thank you and keep on the good job!
