Your private TDEE, BMR, calorie and macro plan, now iOS 27-ready with on-device Energy Insights, Shortcuts and widgets. No account, ads or tracking.
Calculate your TDEE, BMR, daily calorie target, and macros in under a minute. TDEECalc turns a calorie estimate into a practical plan for fat loss, weight maintenance, or muscle gain without an account, ads, or third-party tracking.
WHAT IS TDEE?
Total Daily Energy Expenditure (TDEE) estimates how many calories your body uses each day. TDEECalc combines a research-backed BMR equation with your activity level, goal, and pace to provide a useful starting target, not a guaranteed result.
YOUR CALORIE AND MACRO PLAN
• Calculate TDEE and BMR
• Choose fat loss, maintenance, or muscle gain
• Select a realistic goal pace
• Get protein, carbohydrate, and fat targets
• Use metric or imperial units
• Keep calculator experiments separate from your active plan
IOS 27 READY
On supported iOS 27 iPhones, private Energy Insights use Apple’s on-device Foundation Models to explain your structured progress data in plain language. Your profile and health data are not sent to the developer, cloud AI, or Private Cloud Compute. Deterministic insights remain available when the model is unavailable.
Use App Shortcuts to view TDEE, BMR, calorie targets, log weight, and open progress. Small, medium, and large Home Screen widgets keep your plan visible at a glance.
LEARN FROM WEEKLY PROGRESS
Log weight and complete flexible weekly check-ins. TDEECalc separates raw measurements from a smoothed trend, estimates observed TDEE when enough data exists, and may recommend a cautious calorie adjustment. Your plan changes only after you confirm it.
OPTIONAL APPLE HEALTH CONNECTION
With your permission, TDEECalc can read body mass and dietary energy from Apple Health. Access is optional and read-only. Health samples are processed on your device and are not copied into app backups or sent to the developer.
RESEARCH-BACKED METHODS
• Mifflin-St Jeor
• Cunningham
• Katch-McArdle when body-fat percentage is available
• BMI and ideal-weight references
PRIVATE BY DESIGN
Your profile, plans, calculations, and progress stay on your device. There is no account, advertising, third-party analytics, or cross-app tracking. Core calculations work offline.
TDEECalc provides educational wellness estimates, not medical advice. Results are starting estimates and may differ from your actual needs.

The app is simple and excellent with multiple formulas available and references to back it up. Super well done!
