Apple App instructions/ features?

Is there a sticky or link to an explanation of how to use all the features on the iOS app? Like, what all the icons mean and long press/ tap sets, etc? I have search and found bits ex-pained here and there but no concise explanation. Also. Is there one for the Android app too?

Every icon also has text next to it telling you what it is for there are tips on a number of views


Sorry - I don’t see those text explanations in my iOS app.

You may need to upgrade to iOS 17
