this program is a very cool way to keep a couple close and be mindful of each other. interface is a bit difficult due to the in app sales tactics. be easier if the sales/ donations is easier and streamlined. overall, I like the program to keep us connected. just hard to navigate.

Me and my partner have been enjoying the app so much, however, my partner tends to be lazy to answer questions sometimes. I think having the ability to keep answering questions everyday but keeping them hidden from him would motivate him to know what I have answered and hence answer the questions himself. So it would be a great feature if you can implement it in my opinion!
