Current app assessment
I did assessment of the existing app, including quick usability testing inside our team. It turned that to go to another screen, users had to swipe. So every time they need to switch to another screen, they do swipes. Users said that it is quite annoying, because they had to do a lot of extra gestures.
Informative screens were full of descriptive text, which did not change. So at some point users became blind to it.
Share button was not noticeable for users. So they did not really engage with the content.
