A simple piece of software that syncs itunes music, podcast and picture libraries between mac's and android mobile phones. I don't know if there is better (or cheaper) software out there, but this works great on my Galaxy S.
There is also a free version, however instead of scanning and syncing new files it rewrites the entire library every time it sync's, meaning syncing times of in excess of 20 minutes depending on the size of your music library.
I thought it was a bit expensive at $21.99 US, but for $9.99 US ($10.69AU) it seems like a good investment, at least in terms of time.
Deal ends February first.
Would double twist be an alternative?
