Congrats on the idea!..

But some of the use cases seem a bit childish.

Maybe I'm too mature but it's much easier to just suck it up and be honest and open about a topic. This seems like it would enable a father to forgo talking about a difficult subject with his child because he would have a false sense of "well at least I tried" from using the app. Long story short I think the idea risks decaying a relationship more then strengthening it.

I'm probably wrong though! I'm wrong constantly.

Good luck!
