How it works › Finding your way
Tap a category to open it and see its subcategories. Keep going until you reach the individual exercises you want to practise.
What a card tells you
Every category card carries two numbers: how many exercises behind it you have finished, and how many are open to you now. The second is the one that says where you can go today — if there is nothing there, nothing behind that card is open yet and you are better off looking elsewhere. In practice it is absent, because everything is open.
