Enter Autopilot
Target 2,116 kcal. Over 5 days your weight moved up and down around 62.9 kg and held, so the Target rose to 2,316 kcal.

WhispCal starts from the same estimate as most apps. Then it moves your Target on your weight. You confirm each change.

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.

The formula

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.

The balance

Eaten1,800
Burned+550 · 2,350
−0.5 kg

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.

The reading

Day 7Day 14Day 28

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.

Metabolism over 4 months: Real Burn swinging above and below a flat estimate

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.

Frequently Asked
Questions

Is WhispCal free?

Yes. Calorie tracking, barcode scanning and your measured Real Burn are free, with no time limit and no card. Free includes 6 AI text logs and 1 voice log a day. Pro makes AI logging unlimited, adds photo logging, and unlocks Cut, Reverse Diet, Bulk and Reset. The stores set the local price; the pricing page has the figures.

How does AI voice logging work?

Say what you ate the way you would say it, like 'two eggs, toast with butter and a coffee with oat milk'. WhispCal splits it into foods and fills in calories, protein, carbs and fat. You check it, then log.

What is Real Burn?

It is what your body actually burns, measured from what you log and how your weight moves. When you diet, your body adapts and burns less. Real Burn sees that; a formula can't. It is free.

What if I go over my target?

One day changes nothing. Autopilot reads your weight trend over several days, so a big Saturday dinner does not move your Target. Log it and carry on.

How is WhispCal different from MyFitnessPal?

WhispCal measures your Burn instead of holding one fixed number. It tracks how your Burn changes, moves your Target on your weight trend, and logs a meal from one sentence. Measuring is free.

Does WhispCal track protein, carbs, and fat?

Yes. Set targets for protein, carbs and fat, and see which foods each one came from. Fiber is tracked too, against a target set from your calories.

What platforms is WhispCal available on?

WhispCal is available on both iOS (App Store) and Android (Google Play). It's free to download with optional premium features.

What is Autopilot?

Autopilot compares your weight every 5 days by default, or any window from 3 to 15, and moves your Target by 200 kcal when the trend calls for it. You confirm, postpone or adjust each change. It guides you through 6 phases: Peak Maintenance, Cut, Reverse Diet, Bulk, Reset and Cruise. Peak Maintenance and Cruise are free.

Can WhispCal help with weight loss?

Yes. WhispCal measures what you burn, and Autopilot moves your Target as your body changes, so your deficit keeps working as you lose.

Is WhispCal available in French?

Yes, fully: the interface, voice logging, Autopilot Briefs, and a verified food catalog with French names and preparations like cuit, cru or au four. Change it in Settings → Language, or let the app follow your phone.

Can I customize how WhispCal looks?

Yes. WhispCal ships 10 themes, from light ones like Linen and Cool Mist to OLED Black and Obsidian. Each one re-balances every chart, calorie zone and macro bar, not just the background. Switch in Settings → Appearance.

Does WhispCal have streaks or rewards?

Yes. A daily logging streak, and badges for your first meal, for 50, 100 and 1,000 meals, and for logging a week, a month and a year. It keeps tracking a habit, not a chore.
