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.}

This is the best iPhone app I have tried (I have not tried all). It gives you all the settings and output you need to access the performance of a mechanical movement, and slo to troubleshoot certain issues. It is as good as a special machine BUT is heavily dependent on correct microphone usage. This is what I did. I bought USB-C ear pods from Apple for £19. The button has a microphone on it (it’s the side of the picture of the microphone). Basically wedging that between the back of the phone and a cushion from a watch roll (picture of microphone facing watch back). Then closing the watch roll, running the cable of course out to the phone. Then putting the watch roll under my duvet and covering it further with a pillow (don’t know if the pillow is necessary). Make sure the watch is fully wound, as if not low amplitude may show better results then you get when the heart is fully pumping. The settings I use are tick detection noise cancelling on. Super gain off. Tick detection algorithm v2. Diagram noise reduction period medium or high. Beat detection auto. Works like a charm

Worked for my old pocket watch and my new watch (nh35). Could. Adjusted my pocket watch easily. My orher did not need adjustement but could mesure it easily. V1 works fine, V2 was detecting a lot of noize.

Provides poor and inconsistent readings using the phones microphone. Will recognise external microphone but won’t provide/analyse data (this external microphone works fine with another Timegrapher app).

Works very well if you input your watch specific BPM and lift angle (mine is Seiko turtle so I manually entered 21600 BPM and 53 degrees). I googled these for my specific watch movement (the 4R36A). I used apple wired headphone inline microphone taped to watch case and placed it in a padded box (a pelican case for a camera). I was able to tune my Seiko turtle to 0.1 ms beat error and +12 seconds per day (face up). Best $8 I ever spent! Thank you to the developers for building this fantastic and user friendly app!

I have a Seiko 5 automatic that I’ve owned for about 13 years and which never really kept good time from the factory, typically losing a couple of minutes every 2-3 days. I’d tried regulating it a few times by myself, just making a slight adjustment this way or that, but no matter what I did it never seemed to make much difference, so I’ve just put up with it and changed the time regularly. Fast forward to today and using this app, I was able to immediately discover that the “beat error” - that is the timing between the “tick” and “tock” of the balance wheel - was wildly out, and must have been since the factory. Previously the only thing I knew about this adjustment was that it was the lever you mustn’t touch, because you need a timegrapher to set it correctly, but using this app I was able to set it properly for the first time ever, and then go on to make adjustments to the timing. Lo and behold, I now have a watch that’s accurate to within a few seconds each day. Complete game changer for my Seiko 5 which is finally working as designed after all these years. Thanks!

Finally got it working with the built in microphone. I used it inside a glass top box to lower noise. Wasn’t able to get the quality as much as I would like. If it estimates the BPH, wrong you just get snow and have to start over. Some more set up help would be nice, probably get to 5 stars. Couldn’t get it to work with Bluetooth buds.

Got this to track the accuracy of my mechanical watches. In conjunction with a wired set of EarPods with mic, this app does a great job of measuring accuracy and beat error. The chart is easy to read, displays quickly, and overall tells me what I need to know. Not sure what the poor reviews are about but I’m finding this app to be excellent. Especially for the price.
