Decks inside decks. Cards in the order you put them.
Ordo keeps your flashcards the way you build them: one study space per subject, decks nested as deep as you need, and every card in its place, the order you choose and can change.
Study spaces
One space per exam or subject, each with its whole deck system. Open one and you see only that.
Decks inside decks
Subdecks at any depth. Move a deck into another and its subdecks and cards come along.
Cards keep their order
Every card has a place: 1, 2, 3. Drag it, or send it to a place by number, and the order stays.
