Davinote asks for exactly five favourite categories the first time you register. They are not a preference buried in settings — they are what the home screen is built from, so it is worth getting them right.
The screen appears right after you register
You cannot reach it from a menu. It shows once, immediately after your account is created, with every category listed with its icon and name.
Tap five categories
Each one you tap is marked as selected and a counter goes up. Scroll the list if the categories run past the bottom of the screen.
Change your mind by tapping again
Tapping a category that is already selected removes it and the counter goes back down. Do that if you want to swap one out.
The app will not let you pick a sixth. Remove one first.
Tap Continue
Continue only becomes usable at exactly five. When you tap it you land on your home screen, already filled with businesses from the categories you picked.
Change them later in Settings
Open Profile, then Settings, then the favourite categories option. The same picker opens and your home screen updates once you save.
