the Fitbit mobile app
This app does one single thing - it lets you log your weight today to Fitbit directly from your Versa or Ionic. When adding an entry for today it will, if possible, use yesterdays weight as a starting point. From there you can go up or down.
In order to function this app requires a connection to your phone and internet to communicate with Fitbit.
In settings you can choose your unit (pounds or stone) if you're not happy with the default kg. You also have to visit the settings screen when you first install the app to log in with your Fitbit account. The app will request access to read and write to your Fitbit weight log.
If you encounter errors:
* Try restarting the app on your watch. The app should start working on the second or third try.
* Try rebooting your watch.
Log weight is completely free and open source. Feel free to raise issues if you find any bugs or have suggestions for new features. You can find the project here:
