Movement - Watch Tracker is the ultimate companion app for mechanical watch enthusiasts. Developed by Stefano Attardi, this app offers a range of features to help you set your watch precisely and track its accuracy over time.

With the full-screen atomic clock feature, you can easily set your mechanical watch to the second. This precise clock ensures that your watch is always in sync with the most accurate time.

The "Watches" tab allows you to add and name each of your watches that you want to track. By tapping "Add Point" and aligning your watch's hands with the screen, you can record if your watch is ahead or behind, and by how much. Over time, the app generates trend lines that provide an estimate of your watch's accuracy. If your watch gains or loses 3 seconds per day or less, congratulations, you have a chronometer-quality timepiece. However, if it gains or loses more than 60 seconds per day, it may be in need of service.

The app also offers helpful tips to enhance your watch tracking experience. For example, when adding a point, the hands on the screen automatically jump ahead by 5 seconds, allowing you to add a new point 5 seconds later for increased accuracy. Additionally, if you reset your watch, the app's AI will attempt to detect it and start a new trend line, but you have the power to override this decision.

For those who prefer to analyze their data in detail, Movement - Watch Tracker enables you to export your measurements in CSV format, compatible with popular spreadsheet applications like Excel and Google Sheets, through iCloud Drive if enabled.

Overall, Movement - Watch Tracker is a must-have app for any mechanical watch enthusiast. Its precise atomic clock, accurate tracking, and insightful trend lines provide valuable information to ensure your watch is always running at its best.
