Do I need a computer or desktop app to edit or create decks?

No, decks can be created and edited within AlgoApp directly on your mobile device—no computer or desktop app required.

However, you may find it more efficient to create and edit flashcards on a desktop computer. The AlgoApp web client is available at: https://web.ankiapp.com. AlgoApp is also available as a native app on Windows and macOS. See https://www.ankiapp.com for download links. The web/desktop apps work seamlessly with AlgoApp on mobile devices.
