WHAT'S NEW
You can try full function within 30min. Minor bug fix.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.
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.
4) how do you calculate the pulse drift % abs(max detected frequency – min detected frequency) / detected frequency during 1 detection cycle.
The app uses microphone to measure BPH.
6) are newer versions of the app being developed
3) the average frequency does not always calculate, it stays at NaN The ‘detected frequency’ should be red continuously.
** 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.
– 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

** Please test the app with your watch before you purchase ‘Premium’ upgrade. The app will work as Premium during 30 min.
** You may provide sound sample by sending wav or mp3 file to admin@athumbcut.com
This app is to measure the BPH(Beats per hour) of mechanical watches. It will display time error per day as well.
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.
– Review from Mr. Kojima https://www.thewatchsite.com/index.php/topic,42142.0.html
Not for digital clocks. Not working in noisy environment. Set microphone direction toward a clock.
