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

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).

Watch Tuner Timegrapher

Watch Tuner Timegrapher is an app for testing mechanical watches — both automatic and manual winding. It displays a frequency diagram of your watch and measures the rate, beat error, amplitude, and beats per hour (BPH). The app uses your device’s built-in microphone or a headset mic to record the audible ticks of the watch. For best results, use the app in a quiet environment. Background noise can affect accuracy — complete silence works best, though the built-in noise-cancelling algorithm can filter out minor sounds. The microphone must be in contact with the watch to clearly capture the ticking sound; ideally, place it against the watch’s crown during recording. If you don’t need the frequency diagram, check out the Watch Tuner app. If you only want to measure rate accuracy, try Watch Tuner Lite. If you have any questions, suggestions, or issues using the app, feel free to contact me anytime.
