God idea, but hard to use because of buggy user interface.
But the user interface is not mobile-friendly and seems buggy. Often after I tapped a field, it would ignore anything I typed for about the first 5 seconds.
The 'relationship' field went off the top of my phone's screen and I could go to a second page of options but then could get back.
Entering text was very slow and frustrating because of the issue I mentioned first.
I would strongly suggest making this a free app with advertising and fixing the UI issues.
I'm on an iPhone 6.
