Possibility of Implementing a Share Extension for Adding Cards?

Is creating a share extension to make it easier to add flashcards on the fly from other apps on the roadmap for Anki?

If there are no plans to do so/if this feature isn’t likely to come anytime soon, would there be any problems if I created my own iOS app explicitly for this purpose? (BTW thanks for having such excellent URLScheme support)

You mean a separate app that launches AnkiMobile via URL schemes? No objections from me - it’s probably going to be a fair while until I have the free time to look into integrating such functionality I’m afraid.

Sounds good, thanks for the go-ahead!
