The body fat tracking is based on 4 smartphone selfies that you take, and neural nets. Maybe they got good looking accuracy numbers on their in house test set, but I am extremely skeptical that this will be at all accurate in practice. Also, they had a hardware device designed to take pictures of your body called the "Echo Look" which they canceled not too long ago. Seems strange to introduce new body scanning features soon after that failure.
