Your metabolism, measured.
Every calculator starts from a formula built on averages. WhispCal starts there too, then replaces the guess with what your own days show.
You are not the average.
A formula gives the Burn of a typical person with your weight, height, age and sex. Yours can sit 200 kcal away.
Calories in, calories out.
You burn what you ate plus what your stores gave up. Lose 0.5 kg a week: about 550 kcal a day.
It sharpens every day.
Your first reading takes a week of weigh-ins and 5 logged days. It reaches Medium at 2 weeks and High at 4.
Your Burn moves. A formula doesn't.
Dieting lowers it. Muscle and steps raise it. The dashed line is Léa's formula over 4 months. The solid one is what her body burned.

How Autopilot works →The only tracker
that measures your metabolism.

Why not the tracker
you have?
Most of them hand you a calorie number and ask you to hold it. Autopilot moves your Target on your own data.
Why not MyFitnessPal?
It picks a calorie number and leaves it there. When the scale stops moving, working out why is your job.
Why not Cronometer?
The food database is excellent and it counts micronutrients properly. Your target is still a number you set once and then defend.
Why not MacroFactor?
The closest thing to Autopilot, and it's good. You pay before you try it. WhispCal's first Phase is free, and stays free.
