Diet Tracker Pro is a calorie counter and weight tracker in one. Log meals with calories and macros (protein, fat, carbs), plus weight, exercise and water, and watch your progress to your goal weight in numbers and charts. A daily calorie target based on your metabolism shows what's left today. About 7,800 foods from USDA FoodData Central are built in, and no account is needed.
【Main features】
■ Today at a glance
Calories left, target, food, exercise and PFC bars on top; water, weight and fasting tiles and meal cards below. Review or fix past days too.
■ Automatic calorie target
Basal metabolism comes from the Mifflin-St Jeor equation or the formula of Japan's National Institute of Health and Nutrition. The target follows your weekly pace or goal date and never drops below a safe minimum.
■ Quick food logging
Search by any part of a name, use Recent, Frequent and Favorites, or tap + to repeat your last amount. Save combos as My Meals or copy yesterday's meal. Use portions like 1 cup, 1 slice or 1 piece. Eating out? Quick add takes just calories.
■ My Foods and barcodes
Add packaged foods to My Foods from the label, with their barcode; next time, one scan finds them.
■ PFC and nutrients
Bars track protein, fat and carbs against your targets, along with fiber, salt and net carbs.
■ Weight, body fat and BMI
See your BMI and a goal-line chart from 1 week to all time, and when your plan gets you there. Import old weights from CSV.
■ Exercise
Choose from about 50 activities and enter the time. Calories burned use METs from the 2024 Adult Compendium of Physical Activities: METs × body weight × hours.
■ Water and daily notes
Add water one glass at a time. Mark period, bowel movement, alcohol, eating out or feeling unwell, and add a note.
■ Smart reminders
Meal, weigh-in, water and evening reminders skip what you've already logged, so they never pile up.
■ Reports and calendar
Weekly calorie trend and average, PFC breakdown, days logged and streak, plus a monthly calendar.
■ Widgets and Quick Settings
Log without opening the app from home screen widgets, a water tile or app icon shortcuts.
■ Your data stays with you
Records stay on your device, with JSON or ZIP-with-photos backups, automatic backups (7 generations), CSV export and restore from file. Lock the app with fingerprint, face or PIN. Units: kg/lb/st, kcal/kJ, ml/fl oz; light and dark modes; 40 languages.
