While it might not give an accurate reading, you can still get a precise one (as in, repeated measurements give you the same result), and this is sufficient to tune a given motor, optimizing the dynamic timing advance of your ESC to maximize power output, say.

There's this one now, looks good, but not cheap (and Howard prefers a direct flywheel, without belt/gears):
