Simple by design

One photo. Three decisions.

01

Use a clear photo

Front-facing, even lighting, with your torso and legs visible. Fitted clothing or normal progress-photo attire reads best.

02

Pick only what matters

Select shoulders, chest, waist, arms or legs. The preview leaves every unselected region as close to the source photo as possible.

03

Treat it as direction

The estimate and generated image are motivational guides, not exact measurements, medical advice or a promise of results.
