Calorie Calculator: Macros

Stop guessing how much you should eat.

Enter your height, weight, age and activity level, and get your basal metabolic
rate (BMR), total daily energy expenditure (TDEE), and a daily calorie target for
losing, maintaining or gaining weight. You also get carbs, protein and fat in
grams, so you know exactly what today should look like.

■ Daily calorie target
· BMR, TDEE and your target calories on one screen
· Three BMR formulas — Mifflin-St Jeor, Harris-Benedict, Katch-McArdle
· Five activity levels, from sedentary to very active
· Goals of −500 / −250 kcal, maintain, or +250 / +500 kcal
· Estimated weekly weight change if you hit the target

■ Macros
· Your target split into carbs, protein and fat in grams
· Four presets — balanced, low-carb, high-protein, keto
· Custom sliders to set your own ratio
· A clear donut chart

■ BMI and healthy weight
· Body Mass Index with the four WHO categories
· The healthy weight range for your height

■ Reverse goal planning
· Enter a goal weight and a target date — like "65 kg in three months" —
and see the daily calorie change needed to get there

■ Meal log
· Log what you ate today and watch the remaining-calorie ring
· Save foods you eat often as favourites and add them with one tap
· Entries roll over automatically when the day changes

■ Weight log and trends
· Log, edit and delete weight by date, with notes and note search
· Extra metrics: body-fat percentage and waist circumference
· Filter by 7 / 30 / 90 days or all time
· A trend chart with a goal line and a moving average

■ Stats
· Weekly average change, highest and lowest weight, logging streak
· Entries by weekday, a yearly heatmap, and goal attainment rate

■ Small things that make it pleasant
· Switch units: kg ↔ lb, cm ↔ ft/in
· Tap any stepper value to type a number directly
· A daily reminder to log your weight
· Backup and restore — JSON export/import and CSV export
· Turn your results into a shareable card image
· Light / dark / system theme and six accent colours
· English and Korean

■ Your data never leaves your phone
No sign-up, no login. Everything you enter stays in local storage on your device.
Nothing is sent to any server — not even the developer's — and every calculation
and record works fully offline.

■ Who it is for
· Anyone starting a diet who does not know their daily calorie number
· Anyone bulking who wants to know how much protein to eat
· Anyone who wants the numbers fast, without a heavyweight nutrition app
· Anyone who wants to watch their weight trend over time
