You can record your weight and other measurements once daily. You can also add additional measurements to track.
To log your measurements:
Website:
Click the scale icon under your profile picture on the "My Home" page or click "My Home" then "Check-In" at the top of the page.
Mobile apps:
On the home page you can scroll down to the Progress section where you can see cards displayed.
To view past weight history or add additional tracked measurements simply tap directly on the Progress card. Once the card opens, in the upper left corner, tap on weight to change measurements, or in the upper right hand corner, tap on the displayed time frame (such as 1 month) to adjust your history view.
Alternatively, you can tap the blue "+" button and then tap Weight.
