A jem for a new mechanical watch Thanks to the author I can fix the accuracy of my Hamilton mechanical watch , which is now at 15sec+, and it corresponds to my own measurements. It did take me a day to figure out how to make it read the watch's tiny audio signals, but finally did it, thank you for the app. The key to success is very very quiet room, I even went to my car to test. One suggestion is to make the key numbers bigger, need to use a magnifying glass. Also a button to make a save of the numbers.
I can see the ticks from my watch on the graph at the bottom of the page. Unfortunately, the app seems to not be able to resolve them well enough to get an accurate estimate of my Seiko 7S26. If I were able to view a few minutes with the 1 second scale I might be able to manually estimate the calibration, but I can only view 10 seconds. The accuracy problem may have more to do with the Samsung A tablet microphone then the app itself. Also, it was tricky switching between the tutorial and the settings pages. If it required fewer taps to switch between them, setting up the app would have been much easier.
Way cheaper than a Vibrograph! I like the app. I would have been clueless without the online video tutorial. I'm wondering what the advantage is in the Pro version over the Lite version?
Excellent!! I regulated two automatic watches (both around 40 years old). One lost 5 minutes a day, the other gained two minutes per day. They now run as good as new, well within the 'limits' stated in their manuals. Thank you!!
Wonderful app It took me a couple of tries to get the settings correct but once I did it worked perfectly. Thank you very much to the app developer.
This is one of those apps that does one job and does it good. I had no problem using the app. The dials, the threshold for the peak recognition - everything becomes clear after a few tries. Great product and a very intuitive frontend.

Later versions of Android OS and Android phone models have made it increasingly difficult (and in some cases impossible) to access the options menu via a system-level button. A new button has been added to the main view to alleviate this problem.
