I just downloaded that one, Moody Me, from the app store. It looks pretty good. I had been using Optimism which runs well from a mac or windows but the iphone/ipod one requires it to sync with the website and it's a pain. Too bad, I really liked it because you could personalize symptoms and triggers and it had a lot of room for journaling... I might just have to use the one on my Mac and use the Moody Me for on the spot recording.
