In a perfect world...
you could earn your daily XPs while practicing with Tinycards because the two apps are integrated. But in reality, I do not use Tinycards because I do not get any XP credit even though I like using it better than the duoLingo app or website. Just say'n.
Does it support mass-addition of material yet? I like to create decks in a text file or spreadsheet and add the cards simply and all at once.
No doubt mobile deck creation is useful for some people in some circumstances, but I personally don't like fiddling about on a mobile when I could do the same thing twenty times faster on a computer. TinyCards' native TTS support is its major feature, but I do wish it would shamelessly copy Memrise in some other respects.
