How it works › The app itself
Tap the question mark at the top of a page and you get a tip about that page; ‘Another tip’ gives you the next, until you have seen them all. Now and then one also comes by itself, at most one an hour. You can turn those off in Settings, under ‘Tips’.
What the button looks like
This one. It sits at the top of every page, beside the menu, and it always works — even with the tips that come by themselves turned off.
