Yes. AnkiApp allows you to easily share decks with friends via email.
How can you share a deck?
From the deck screen, open the menu, using the icon in the top-right corner of the screen, then select the "Share" menu item.
You'll then be given a prompt to enter the email address of the person you want to share the deck with.
Enter their email and click "Share", and they'll be sent an email, telling them you've shared a deck with them, and inviting them to get AnkiApp if they don't already have it. If they are a current AnkiApp user, the email will look like this.
How does sharing decks work?
When you share a deck with someone, they have read-only access to the deck. That means that they can study the flashcards you've made, but they can't add any of their own to the deck, or edit or delete any cards you've made in the deck. They also can't modify any of the deck's layouts.
Shared decks are only visible to people you share them with—they are not publicly visible.
Can I share with multiple people at once?
Yes. To share with many people at once, enter all of their emails, separated by commas.
