No, three years ago I successfully used it. I traveled with iPad for 2 months, and it was a life saver, since I created many notes during each day and then merged them into one.
Now my desktop computer is broken and unavailable until August, so I am back on iPad again, and it’s amazing how bad Evernote app for iOS is. Without other apps like MergeEver it’s almost unusable.
Another thing I miss is the possibility to change creation date, but I can’t recall the name of the app that allowed me to do that.
