I really like the App and scale, it works well so far. But I would like to add my circumference and when I click on the button to do that it wants to connect me to a device. I would also like to know if I can see the measurements for the 8 "electrodes" as it is shown in one of the pics in the App description here on Google. Wrote an email to them, let's see what happens :) Otherwise it works without bugs for me and really helps to track weight and see the progress. Using Samsung Galaxy S7 edge.

Can't connect to my scale. I can go to "Add device", find it using Bluetooth and add it, just for the app to tell me there is no connection to the device I just added. Connection was always bad but no it's straight up broken. Don't know why hardware companies are so bad at making the most basic software...

INVASIVE! I bought the scale 2 years ago. The app did not require my location information. Now without having updated it. It suddenly after 2 years does not connect to the scale anymore without location active. Normally I would just delete the app. But i don't want to throw the scale away. I don't appreciate the sudden privacy invasion. What's next? All permissions required to connect to the scale?? Very abusive!
