Clock Tuner Description

A Timegrapher

This app is to measure the BPH(Beats per hour) of mechanical watches.
It will display time error per day as well.

The app uses microphone to measure BPH.

** Recommend to plug a microphone into phone and attach the microphone to the back of your watch.
** Basic version display wave graph and pulse interval histogram.
** Frequency display requires 'Premium' upgrade.

** Please test the app with your watch before you purchase 'Premium' upgrade. The app will work as Premium during 30 min.

Not for digital clocks.
Not working in noisy environment.
Set microphone direction toward a clock.

- Preset example
Rolex or mechanical watch: Target frequency: 4 or 5Hz, Sample duration: 2Sec, Sensitivity: manual 50
Most pendulum clock: Target frequency: 1 or 2 Hz, Sample duration: 5 or 10 Sec, Sensitivity: medium

FAQ.
1) in the settings there is a sensitivity option with a high, medium, low and 3 manual settings, can you explain how this changes the results

It determines sound amplitude threshold for detecting clock sound. If your clock sound is loud you may reduce sensitivity. This will allow more environmental noises.
If you increase the sensitive, you may measure hand watches. But small noise may measurement errors.

2) why does the detected frequency change between light grey, black and red
Red means smaller drift during the measurement interval while grey means that measurement may have an error.

3) the average frequency does not always calculate, it stays at NaN
The 'detected frequency' should be red continuously.

4) how do you calculate the pulse drift %
abs(max detected frequency - min detected frequency) / detected frequency during 1 detection cycle.

5) what are the 2 graphs showing and what data are you using for the calculations
The size of bars in the upper graph should be almost the same.
The bottom shows amplitude of sound wave recorded from micro phone.

6) are newer versions of the app being developed

** You may provide sound sample by sending wav or mp3 file to admin@athumbcut.com

Comments about Clock Tuner Android Version

I've been using this for a couple of years now, on different Android versions. Works really well on my mechanical watches. Was able to get them to within a second a day. Haven't had many problems with outside noise, mostly use medium sensitivity. Not able to get it working with a pendulum wall clock, even though it's in a case. Would be great if there was a decent description of the graphs, scales and settings in the app. The FAQ here is helpful, but has big gaps. Great value for money, despite limitations.

The display has tiny, tiny, tiny characters, and no ability to zoom in on the rate trend part of the window...the waveform from the microphone takes up much more screen space than needed, whereas the error/rate part is too small to be readable. Otherwise, it seems quite accurate. Too bad it's A TRIAL FOR 30 MINUTES ONLY.

I downloaded this on to my phone. After the trial period it stopped so I paid for the upgrade. It then worked for a while and stopped. I could only get it going by un and reinstalling. I then saw the earlier comment about clearing data and it works again each time. Thanks for that. I have had trouble checking 4 old watches in that the frequency jumps about all over the place. I don't know if it is that the watches are worn or the app not working on the higher frequencies with the remote phone mike. I have now tried it with the internal phone mike and it gives far better results. I didn't think that it would be sensitive enough. I wrap the watch and bottom half of the phone in a cushion to keep out background noise. It works well with clocks.
