Timegrapher X analyzes the ticking sound of a mechanical watch to measure its accuracy rate, beat error, and amplitude. The app is specifically optimized to work with the Apple EarPods' headset microphone. Ideally, the headset microphone and the watch crown should be slightly pressed together, as this greatly improves the level of detail and diagram quality. The better the contact, the stronger the signal. https://timegrapher.app/ Timegrapher X consists of two separate modules (tabs): The "INSTANT" module shows how the watch is behaving in the short term, or "right now". It is very similar to a traditional timegrapher device, with the added benefits of a real-time waveform display and a high-detail diagram display. The "LONG TEST" module is a graphical data logger, which helps you observe the long-term behavior of a watch. Various chart indicators are available, such as average rate, moving rate history, rate drift over time, and more. Long-term measurements for up to 12 hours can be conducted for in-depth analysis of the watch being tested. Timegrapher X Pro (in-app upgrade) provides these additional features: • Save and share branded, printable PDF reports for each measurement • Export raw measurement data as a .csv file for spreadsheet analysis • Conduct long-term measurements for up to 120 hours For demo videos and documentation, please visit: https://timegrapher.app/
