Step on the Tanita BC-401 InnerScan and it recognises who you are, takes a reading and sends it to the Tanita app over Bluetooth. It is a home body composition scale for people tracking training or weight change over weeks and months, with room for five users plus a guest.
What it measures
- Weight and BMI
- Body fat % and total body water %
- Muscle mass and physique rating
- Bone mineral mass and visceral fat
- Basal metabolic rate and metabolic age
Each reading is saved in the app, so you can see trends, set goals and plan your training around them. The recall function brings back your previous reading on the scale itself.
Modes and users
There are adult, guest and athlete modes. Auto recognition picks your profile from your reading, so you don’t have to press anything before you step on. Metabolic age covers 18 to 99 years, and children aged 5 to 17 get body fat % and total weight readings.

Tanita InnerScan scales like this one read the body as a whole. The Tanita RD-545 adds separate fat and muscle readings for each arm, each leg and the trunk, using dual-frequency BIA, if you want to track changes by body part. See both, and the rest of the range, in Tanita Scales.
