A replacement for the YFD iPhone app
Dayta is a simple generic item tracker that allows custom tweets of
items, so you can set it to tweet "D @YFD %t %v" or something and
that should work just fine.

I have no affiliation with this app and just discovered it
yesterday, but it seems to work as a replacement.
