Watch Tuner Timegrapher

Watch Tuner Timegrapher is a mechanical (automatic or manual winding) watch testing application. It displays a frequency diagram of the watch and measures rate, beat error, amplitude and beats per hour.

The application uses the build-in or headset's microphone to record audible ticks of the watch.


Use this application in a quiet environment. Any ambient noise can affect result accuracy. Complete silence is the best however noise cancelling algorithm can help to eliminate not very loud sounds.The recommended way to record the ticks is to touch the crown of the watch with the headset (earplugs) microphone.

If you don't need the frequency diagram, look at Watch Tuner app.
If you want to test only the rate accuracy, try Watch Tuner Lite.

If you have any questions, suggestions or any troubles using this app - don't hesitate to write me.

Timegrapher

Needs improvement, not for real job. Keep developing.


Not working
Greyfox1

Won't work on my iPod touch 6 running ios 8.4. All it does is show a blank white screen. Great concept if you can get it to work.


Comprehensive app

Goog comprehensive App with lots of data.


Worth every penny

Was able to adjust my grandfather's watch to run accurately after sitting in a box for 20 years.

This is a really good piece of software. It works using the iPhone microphone. It plots a time graph...cool. The lift angle can be adjusted..cool. It shows beat error and amplitude. Money well spent, great job !


Great time grapher!

I bought a used COSC rated watch that was about a year old. It was losing 10s/day. Using this app I was able to regulate it to +.2s/day. My beat error is .1ms so I didn't mess with that. It plots near perfect. This is a well thought out app.


Great alternative to the real thing

I just started getting into watch maintenance and bought a few cheap mechanical watches on eBay. I'm impressed not only with the many different parameters this app can record, but with the fluidity and precision of the live data appearing on the screen as it's recording. Very very happy with this, especially for the value considering a cheap timegrapher would be at least over $100 and probably not as well made.


Inconsistent from device to device
Barihunk

I bought this app to look at how well my watches are running. The rate it reports is inconsistent between my iPad and iPhone. The iPhone reading appears to be reasonable but the iPad shows a rate that is -30 seconds different on the same watch measured simultaneously. Not sure what is the problem but since there are very few controls it appears to be an error in the app itself.


Fantastic!

I don’t know why this app doesn’t have more ratings; it’s fantastic! The display is just like a real timegrapher and works well. With just my headphone mic I was able to get a strong enough signal to regulate my Seiko 5 to within 1 sec/day, and reduce the beat error to 0.5 ms. I’m pleased as punch!


Useful if used correctly

Initially, I had far more failures than successes in trying to obtain good data from this app. Even worse, when using the built in microphone of my iPad, it magnetized my watch, causing a watch that typically runs at -1.1 sec./day to gain about 40 seconds in a day, and then to run about 5 sec./day slow. After purchasing a demagnetizer, my watch now appears to be back to normal. I also purchased an earbud with a microphone, and am having more success obtaining reasonably accurate results, keeping in mind that this is an inexpensive hobbyists tool rather than a professional tool costing hundreds of dollars. Although microphones do not create strong magnetic fields, speakers do create strong fields, and the speakers on an iPad are directly adjacent to the built in microphone. An iPhone appears to be a bit safer since the speakers and microphone are on opposite sides of the device, but caution would still be wise. Also, keep in mind that the earpieces of the earbuds emit a strong enough field to affect a compass needle, so keep the earpieces away when using the microphone. I would encourage the developers to revise their instructions to specify use of the earbud microphone only, and not the built in microphone.
