I like the content in this app, with the intent to start meaningful and unique conversations with my wife. This itself is enough to keep me using the app!
That being said, the app is a bit clunky to use. Its sometimes slow to respond (on my iPhone 6S), and in some cases the interface doesnt respond at all.
Ive found this to be fairly consistent when answering a quiz question that immediately shows me the results of our match. If you try to leave a comment at this point, the app hangs. Ive had to shutdown the app in order to get it to go back. It forgets that I answered that question then - so when I answer it the second time, I dont try to leave a comment. I can go back in later and leave a comment without a problem.
I think a few tweaks and this could be a solid user experience.
Again, really good concept with good writing & content. 90% solid execution.
