No home/profile button in Pinetrest?

[Snapphane]

Hi, my girlfriend has an issue with the Pinetrest app. After browsing around and hopping from one board to another, she wants to "go home". Either to check her profile or to access the search. But there isn't a button for that. Sure you can push "back", but after 4 days there is alot of back to access. Right now she just permanently shuts down the app, which resets it for next start up.

Anyone who knows a better solution?
