I've downloaded and installed the thing, but forgot to go to the pilot's box last Saturday and take some recordings. I'm wondering whether the estimates it comes up with correlate well with other speed-measuring techniques.

G'day Steve I have it on my phone and it does work quite well but not very well at McCoy field. I think this is because of the echo you get off the buildings I think that upsets it. I have managed to get a few readings standing in the pilots box and as long as the plane is reasonably loud and as long at it passes close by, you might get a good reading. You have to adjust the settings according to what you want to measure as well.
I have used it to measure the speed of some planes on youtube. If you find one where they are using a radar gun to measure the speed of a plane and turn your speakers up a bit it will measure pretty close, with in about 5%
Come allong to Pitt Town and try it out.
There will be plenty of fast planes and there are no buildings to cause echos
