I've used AnkiApp extensively for the past year, as I've been learning Indonesian out on Bali.<p>I have come to the conclusion that shared decks don't work, at least not for me. The reason is that actually assembling the deck has turned out to be almost as valuable as practising with it.<p>I've got well over 1,000 cards in my Indo deck right now. I had to go find every translation and decide whether synonyms should be on the same card. That activity produces its own kind of learning.
