Been using this app for the whole of my 2 year relationship, we have the premium subscription. Questions get a little strange after so long and we have no idea what some of them mean. The new update though was unnecessary, we didn't need a second mon. It would have been fine if it wasn't ugly. (we named it AbortionMon because we don't want it.) The art style just doesn't fit with the game, it looks too corporate. It can just be ignored, but there was really no point to that thing

The ads are getting out of control! You have to feed the egg four times a day, and each time, there are very long ads that you actually have to play the game for instead of using a timer. A lot of the images in the app that are also just videos (even the loading screen). What could have been a great way to become closer to your partner has now been squeezed out of enjoyment due to these ads

Super cute and exactly as advertised. some things I enjoy is that you get to decorate your little house by saving the in game currency pebbles. You can earn these with food and daily 3. I wish we could add multiple memos and save them. Then we could go back through a "gallery" and select the one we want on the widget. I also wish we could skip some questions and get a different one. That would be amazing other then that I love this adorable couples app!
