Can somebody explain Tiny Cards?
I don't quite understand how to make your own decks, follow people and see your progress. The answers to those questions and any other help will be gratefully received. Thanks.
I don't know about the app (Android still doesn't have it) but on the web version it is very easy to add your own decks. At the top of the page click "+Create" and then fill in the details. The big plus sign allows you to add cards.
You can click the "Favourite" button to make a lesson or a whole course your favourite and this makes them appear in the carousel which shows your favourites (obviously). You can see your progress there by how much the yellow bar is filled in. I don't know of any way to see how many cards or lessons you have done overall, I don't think there is any way.
You follow a person the same way really. You need to find a persons page first, and the easiest way seems to be to pick a deck and then click the creators name. You then get the chance to follow them. For example if you select a Duolingo lesson (eg: French Verbs) then you can click Duolingo (the creator) and then follow them. I don't know what you get out of that, but I assume you'll see when the person creates new decks.
