I have used Anki before, but I didn't care much for it. I think my problem with it was that it would overheat my phone. That said, I have changed phones since then so maybe I'll try it again. I know that they work with kanji, but I'm wondering if they had a grammar set, too. Japanese (like English) has so many different grammar rules. I'm on the 22nd lesson in Genki and I hate having to flip back to remind myself how to construct a certain sentence.
In other news, this morning at the lovely hour of 5 AM I checked out Orange Theory Fitness. It was insanely fun, but damn would it be expensive to join. Does anyone else have one in their area?
