The scale itself is in the way and people often forget to step on it, and when they see the numbers, it's stressful. The smart bath mat can be left out and won't get in the way. The numbers are hidden so it doesn't cause stress. Just step on it for 3 seconds every day after your bath and your weight changes will be recorded on your smartphone. Unlike typical smartphone-linked scales, it connects to Wi-Fi so there's no need to connect to Bluetooth every time. It's USB charging so no batteries are needed and it can be used for six months on a full charge.
