I have to agree that I too was disappointed.

I downloaded this to my iPad hoping it would give me a more portable means of updating and adding to my tree whilst on the go, but its really just a directory.
I guess if you wanted to check a name, it's fine.
But any more than this and I wouldn't bother using it.

I had no issue installing or logging in, and it did download the list of a few hundred names super fast...

But there isn't anywhere NEAR enough functionality.
I'd love to see it expanded and added to, as I think it could be an amazing app!
So much potential untapped!
