Hairspring turns your device into a powerfulmechanical watch timing machine. It measures the precision ofmechanical watches, with an accuracy of at lease ±1s/day, byanalyzing the tick-tock sound using the microphone of the device.It supports a wide range of frequencies, covering almost allmechanical watches available on the market:- 14,400 VPH- 16,200 VPH- 18,000 VPH- 19,800 VPH- 21,600 VPH- 23,400 VPH- 25,200 VPH- 28,800 VPH- 36,000 VPHIn case you don't know your watch's frequency, you may usefrequency auto detect.The measuring time can be set from 30 seconds to 3 minutes, toget a balance between response time and accuracy.An oscilloscope shows the audio waveform in real time. It'squite handy for monitoring the status and diagnosing some commonproblems.The result is plotted in a chart, which can be saved for laterreference. Also, it can record and save a long-time measurement,e.g. for 12 hours, to analyze the long-time performance of thewatch.To use Hairspring, just place the microphone tightly close tothe watch back, then set the parameters. After collecting enoughdata, the result will be shown.A detailed usage guide can be found here: http://www.diversminds.com/Hairspring/Hairspring.php*** PLEASE NOTE ***- This is a Lite version of Hairspring, with the accuracy limitedto 1 min/day.To get accuracy of 1 s/day, you need to upgrade to premium version,using in-app purchase.- Hairspring requires a sensitive microphone. Make sure it workswith your microphone before upgrading.
