One of the best apps for this is "Freebies" from Bitrino. It provides a comprehensive list of the day's FREE programs (ones temporarily made free to boost ratings, etc.)
There are other similar apps, but 3/4 of the stuff I have on my iPod Touch I got for free.
Also, the Hokusai audio recorder/editor is free for the basic version. Nearest thing to Adobe Audition on this platform.
Like Lake Wobegon, but without the lake.
