SECTOR S-01 - S-03 PRO is a newly developed application that works with Sector S-01 and Sector S-03 Pro smartwatches. The app provides a comprehensive set of features to help users monitor their fitness and health. The app can sync your steps, calories, mileage, heart rate, sleep, and exercise records recorded by your watch. The user interface of the app is intuitive and displays data in a meaningful way. The app also allows you to set sedentary alerts, alarm clocks, schedules, and backlight of your watch. Additionally, the app can sync weather and AGPS files to assist in locating the watch. The app stores all your data locally and does not upload it to any server.

The app provides access to the instruction manual through the Sector No Limits website. The app also displays phone notifications on your watch after binding and authorizing the devices. The app is free to use and the developer, Morellato Spa, promises to listen to user feedback and make improvements. However, it is important to note that the app does not store any personal information for other purposes and all health data is for reference only. The app should not be used to replace the opinions of healthcare professionals. For accurate data, please consult your doctor.
