Can AnkiWeb shared decks be used in AlgoApp?

Yes, often

Many AnkiWeb shared decks can be found directly from AlgoApp's "Get Decks" search.

If the deck appears in search

Open "Get Decks", search for the deck name or topic, and download it.

If the deck does not appear

Download the deck from AnkiWeb as an APKG file, then import it into AlgoApp using "Import Decks".

Important

Card content can be imported. Existing Anki review history and scheduling data do not transfer.
