In reply to nwclimber:
The Crimpd app works on Android, and has multiple fingerboarding options.
I also love Impetus -- not climbing-specific, but it's an interval timer which lets you build your own workouts (complete with counting down seconds, optionally reading out the name of the next exercise, etc.)..
So if you know what sort of fingerboard training program you want (repeaters, max hangs, whatever), you can make a timer for it to your exact specs.
