Watch Tuner Timegrapher 对比 Watch Tracker 的使用情况和统计数据

Watch Tuner Timegrapher is a mechanical (automatic or manual winding) watch testing application. It displays a frequency diagram of the watch and measures rate, beat error, amplitude and beats per hour.  The application uses the build-in or headset's microphone to record audible ticks of the watch.  Use this application in a quiet environment. Any ambient noise can affect result accuracy. Complete silence is the best however noise cancelling algorithm can help to eliminate not very loud sounds.The recommended way to record the ticks is to touch the crown of the watch with the headset (earplugs) microphone. If you don't need the frequency diagram, look at Watch Tuner app. If you want to test only the rate accuracy, try Watch Tuner Lite. If you have any questions, suggestions or any troubles using this app - don't hesitate to write me.

Watch Tracker

Watch Tracker is a revolutionary app for tracking the accuracy of a wristwatch. It's dramatically easier and more accurate than any previous method. Just tap a button when the time on your watch matches the time displayed by the app, and Watch Tracker does the rest. It synchronizes with an atomic clock, measures and records the difference, and displays graphs of all the data points you've recorded. - Uses best-fit analysis to accurately calculate how many seconds your watch gains or loses per day - Displays graphs of rates and variance - Can track multiple watches simultaneously - Saves data in CSV files that can be opened with any spreadsheet software Watch Tracker is made by the developer of tChess (the chess app that was featured in Apple's "Learn" commercial for the iPad) and Learn Chess (the Apple Staff Favorite e-book).
