Description

A Timegrapher

This app is to measure the BPH(Beats per hour) of mechanicalwatches.
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 themicrophone to the back of your watch.
** Basic version display wave graph and pulse intervalhistogram.
** Frequency display requires 'Premium' upgrade.

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

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, Sampleduration: 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 changesthe results

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

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

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

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

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

6) are newer versions of the app being developed
