Many months ago, an American Watch maker decided to make an iPhone App which could be used to determine the accuracy of a mechanical watch similar to those professional timing machines.
I tried the App when it first came out and it was totally unusable! After contacting the author to complain, he pulled the App from the AppStore and he has been sending me a steady stream of Betas to me and a couple of other early adopters to evaluate.
After a number of upgrades, it finally reached a very usable state. Background noise suppression works well and the bph frequency determination works great.
Here's a pic of me testing the accuracy of my Omega Speedmaster. Based on my monthly observation, relatively accurate to about 1 Second
The App can be found here:
