Optimal

Personalised, not averaged

Your numbers, graded against your optimal.

Optimal for your body, not a population average. We build a personalised optimal range for every metric, show our working with the science behind it, and give you one small thing to do next. It even reads BMI alongside your fat-free mass index and body fat, so a muscular build is read as muscle, not mislabelled as obese.

Optimal for your body

A personalised range for every metric, not a population average. It reads BMI with your FFMI and body fat, so muscle is never mislabelled as fat.

One thing to do next

Not a wall of data. One tiny, specific action, framed around the person you are becoming, with the why attached.
