Chronometer APP

I have released the iOS Chronometer APP to track the daily rate of chronometer watches. The APP receives an accurate time signal from a Swiss NTP server (metas). The captured data can be exported to iCloud as a CSV file. This CSV file can then be used for further analysis in Excel. Before you start set your clock to atomic time. Do not set the clock during the recording process! The Chronometer APP requires an internet connection to get the accurate NTP time. 1. Wait until the NTP time appears green. Then the time signal is accurate. 2. Create a picture of the clock face. This is done by pausing the video feed. No image is saved, as this would cause unnecessary time delays. 3. The time server registers the time when the image is fro- zen. This time is displayed below the photo as a picker. Now correct the registered NTP time with the time on the dial. This gives the exact difference to the NTP time. 4. Optionally you can specify the altitude above sea level. Altitude variations can have an influence on the clock's rate behaviour. 5. Now save the time under Save Rate. The APP compares your daily clock time difference with the NTP server. You can check how accurate your clock is and adjust the rate if necessary. Wait until you have 15 days of data before concluding the accuracy of your watch. The origi- nal chronometer certification of your clock was also created in 15 days. A mechanical wrist watch with less than 10 seconds deviation per day is very precise. Under Settings you can make further specifications for the clock. The name of the watch, the frequency of the escape- ment and the moment of inertia of the balance in mg-cm². With Export CSV a file is saved to the iCloud. Date / absolute rate / daily rate / altitude above sea level. This APP is optimized for iOS 15
