Know your true burn. TrueBurn is a fast, honest calculator for TDEE, BMR, protein, body fat, macros, and more — and it can learn your real metabolism from Apple Health. Below are answers to common questions. If yours isn't here, email us — a real person reads it.
We aim to reply within a couple of days.
How do I get my numbers?
Enter your sex, age, height, weight, and activity level. TrueBurn instantly shows your TDEE, BMR, protein target, and more — and every result shows the exact formula it used. Switch between imperial and metric anytime.
What is "Adaptive TDEE"?
A formula is a population-average guess. Adaptive TDEE measures your real daily burn from your own data: over a rolling three weeks it compares your average calorie intake with your weight trend. It shows a measured number once there's enough data (about two to three weeks of logging), with a confidence indicator — no wild swings.
How do I connect Apple Health?
Open Adaptive TDEE and tap Connect Apple Health, then allow the data in Apple's permission screen. TrueBurn reads only your weight and the calories your food app already logs to Health — it never writes anything. Connect once and your numbers stay current automatically each time you open the app.
Do I have to log food in TrueBurn?
No. TrueBurn is not a food logger. It reads the calories any app you already use (MyFitnessPal, Cronometer, Lose It!, and others) writes to Apple Health. If you don't use one, you can type a daily calorie total in a couple of taps.
I don't see an adaptive number yet.
The adaptive engine waits until it has enough data to be honest — roughly 14+ days of weigh-ins and 10+ days of calories. Keep updating your weight and it will unlock, showing exactly how many more days it needs.
Where is my data stored? Is it private?
Everything stays on your device. There are no accounts and no servers, we never sell or share your data, and Apple Health data never leaves your phone. See our Privacy Policy.
How do I reset or delete my data?
Use Reset in the app's "You" tab, or simply delete the app — since data is local, that removes all of it.
Is TrueBurn medical advice?
No. TrueBurn is an estimation and reference tool for education and self-tracking only. Always consult your doctor or dietitian before making significant changes to your diet, training, or medication.
