One useful check-in.
Weight at a similar time and under similar conditions when practical. Consistency matters more than perfection.
Add today’s weight
Waist and neck measurements calculate body fat automatically; the female equation also uses hip circumference. Calories, notes, and a progress picture are optional. Saving again updates the selected date.
Your weight trend
Daily readings plus a smoothed trend.

Try a calorie scenario.
A projection is a planning range, not a promise. Your real maintenance needs and weight response will change over time.

Scenario curve
Center estimate with a deliberately wide uncertainty band.
The model uses roughly 7,700 kcal per kg (3,500 kcal per lb) and recalculates estimated energy needs as projected weight changes. Water, glycogen, digestion, adaptation, training, medication, and health can make actual results differ substantially.

A supportive estimate, not a diagnosis.Day-to-day weight can move for reasons unrelated to body tissue. If you are pregnant, under 18, have an eating-disorder history, have a condition or medication affecting weight, or are making a large change, use this only with advice from a qualified clinician.
Community prototype
A forum for the whole journey.
Share progress, ask questions, compare routines, and support people moving in either direction.

Secondary tools
Useful estimates, kept in context.
These tools reuse your profile where possible. Each is a screening estimate with limits—not a verdict about your body or health.
Adult screening tools only.Reference categories can vary by age, ancestry, clinical context, and guideline. A clinician can interpret measurements alongside blood pressure, labs, history, and symptoms.
