Who Petal is for
The health metrics you’re missing
The fat you can’t see
Visceral fat wraps around your organs, where scales and mirrors can’t see. It can rise even when your weight doesn’t.
3.7× the risk of developing multiple heart and metabolic diseases for people with the most visceral fat. UK Biobank, 2025
How you move matters
Walking speed and steady, balanced steps reflect your strength and long-term health. Petal tracks them as you go about your day.
An early fall signal: how steady your steps are predicted falls over the next year, when strength and balance tests didn’t. Hausdorff et al., 2001
