A TimegrapherThis 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.- Review from Mr. Kojimahttp://www.thewatchsite.com/index.php/topic,42142.0.html- Preset exampleRolex or mechanical watch: Target frequency: 4 or 5Hz, Sampleduration: 2Sec, Sensitivity: manual 50Most pendulum clock: Target frequency: 1 or 2 Hz, Sample duration:5 or 10 Sec, Sensitivity: mediumFAQ.1) in the settings there is a sensitivity option with a high,medium, low and 3 manual settings, can you explain how this changesthe resultsIt 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 redRed 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 atNaNThe '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 calculationsThe 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** You may provide sound sample by sending wav or mp3 file [email protected]

Lots of people like me have to use two applications instead of one.This clock is very simple and useful. 12 fonts on your choice. 8colors plus one custom color. That's all. Swipe left/right toswitch the color. Swipe up/down to switch the font. Double tap toturn on/off sound like metronome. Long press to start timer orstopwatch and select custom color, set military time. I've madethis clock only for myself but lots of people who've seen them askme to save them on the play market. Done. If you want someimprovements - welcome! Absolutely free, no ads, no popups. This isnot only application but also a widget! It can be used on thedesktop and it will display the same information in the same formatas in the application itself.
