WeightPilot

Reach your target weight at a steady pace, and stay there.

WeightPilot gives you one number each day, the throttle, that tells you whether to eat a little more, a little less, or about the same as usual. You don't count calories or log food. You just weigh in each day.

How it works

Weigh in daily

Enter your weight by hand, or connect a Withings scale or Apple Health / Health Connect so weigh-ins arrive automatically.

Follow the throttle

Each weigh-in updates a model of your body, and it sets the day's throttle. Push it forward and eat a bit more; ease it back and eat a bit less.

See your stable weight

Day-to-day swings in carb stores and fluid are separated out, so you can see real progress through the noise on the scale.

Lose, gain, or maintain

Set a target weight or body fat percentage. WeightPilot keeps your rate of change moderate to protect lean mass, then holds you at your target.

Built on control theory

WeightPilot uses the same kind of feedback control that keeps aircraft stable in flight. A physiological model tracks how your body stores energy as fat and as glycogen, and it learns how you respond to the throttle. The longer you use it, the more accurate it becomes.

WeightPilot is a general wellness tool, not a medical device, and it doesn't give medical advice. Talk to your doctor before you change your diet, especially if you are pregnant, have a medical condition, or have a history of disordered eating.
