I have the StroboClip tuners for normal use, and this app on my iPhone and iPad for my bench when Im working on my electrics. Simply connect a A/D converter to the iPhone or iPad and a regular guitar cord to the device.
I do my own intonation so my guitars are dead-on always, and optimize the pickup height by raising them until I see the harmonics start to pulse.
