The scale is intended to be used by a single user to ensure accurate and consistent weight measurements. If the app identifies a weight that may not belong to you, you will be prompted to verify it.
Incorrect weights or weights from others can also be deleted in the app.
To do this on an iPhone, tap on the profile icon on the upper left side and then tap on the weight tab on the next screen. You can then swipe right on any incorrect weights to delete them.
To do this on an Android phone, tap on the profile icon on the upper right side and then tap on the weight tab on the next page. Then, tap once on the incorrect weight to delete it.
