ChronoLog - Watch Accuracy 4+

ChronoLog is the easiest and most accurate way to measure the performance and accuracy of your watch collection. Add your watches and take measurements with a photo or a tap. Tag measurements and view trends over time so you always know how you're keeping time!

First, you add a new watch to the collection. This starts an initial timing run in which you take measurements. Each measurement includes the true time and the time on your watch face. This is used to calculate an offset from true time. By collecting these measurements, we can calculate your watches' accuracy and rates of change per day, and present the information in attractive data visualizations. Each measurement can be tagged to let you know if the measurement occurred, for example, over night, or right after a winding.

Data you collect stays on the device, and you can export it as CSV should you wish.

ChronoLog, as a comprehensive watch timing tool, not only helps you keep track of the performance and accuracy of your timepieces but also provides you with invaluable insights about your collection. With ChronoLog, you can understand the intricacies of your watches like never before, all within a few taps on your device.

Measurements made through ChronoLog are easy and quick. You can either snap a picture of your watch or manually input the time from the watch face. The app then compares this with the true time and calculates an offset. By consistently taking these measurements, the app calculates the rate of change per day for each of your watches. This helps you understand how well they're keeping time and if they need to be adjusted or serviced.

ChronoLog also offers tagging functionality. You can associate each measurement with a specific event or circumstance, such as "overnight," "after winding," or "after being worn for the day." This allows you to detect patterns and correlate specific events with performance, providing you with deep insights into how your watches behave under various conditions.

The data visualization capabilities of ChronoLog are another standout feature. You can view trends over time in an easy-to-understand format. Are your watches gaining or losing time? How much do they vary? These accuracy trends are presented in attractive charts, letting you see at a glance how your collection is performing over time.

ChronoLog respects your privacy. All your data remains on your device, and you have full control over it. If you want to analyze the data in another program or share it with a watchmaker, you can easily export all data to a CSV file.

With ChronoLog, you're not just getting a tool; you're getting a companion that helps you get the most out of your watch collection. The data you collect and the insights you gain can help you better maintain your watches, appreciate their craftsmanship, and enhance your enjoyment of this timeless hobby. Experience the new era of watch ownership with ChronoLog.
