Watch Rate Checker vs Meter

This application is for manually measuring the daily difference of mechanical watches and the monthly difference of quartz watches. Simply touch the button to match the time on your watch to easily measure the day difference. The measurement time can be freely set even during measurement, allowing the user to calculate rough daily differences without having to take measurements for the entire day. Since there is no need to bring the smartphone and watch close together, it can be used safely without worrying about the effects of magnetism.
