Weightsy is a simple weight tracking app that runs exclusively and natively on the Apple Watch. If you are just looking for a basic app to track your weight from your Apple Watch, this is the app for you. It includes US-Standard or Metric units. Set your height, starting weight, current weight, and Weightsy will report on the amount of weight loss and your current BMI (Body Mass Index). This data is saved in the Apple Watch memory, making weight tracking a breeze.

The iPhone app companion serves as instructions and app support only. Weightsy is the perfect solution for someone that just wants to track weight loss on their Apple Watch without any complicated statistics reporting and graphs.
