DataBody: Weight & Diet Log

Your weight jumps around from one morning to the next. DataBody is built to show the movement underneath that noise — and to log the meals, workouts, and habits behind it.

No sign-up required. Open the app and start recording. An account is only needed if you want your data synced across devices.


CHARTS BUILT FOR TRENDS

• Candlestick charts. Each day, week, month, or year is drawn as a candle with its first, highest, lowest, and last weight, so you see the range you moved through instead of a single dot
• Moving averages over a period you choose, so the trend line is as smooth or as responsive as you want it
• Tap any candle to read its exact numbers and date
• The same history, four ways: daily, weekly, monthly, and yearly


STATISTICS

• A table of every week, month, or year: the average weight, and the change from the period before it
• ▲ and ▼ on each row, so a month that stalled is obvious at a glance
• Set which day your week starts on, so weekly rows match how you actually count


WEIGHT

• Log your weight in lb or kg
• Set a goal and a start date, then follow the trend toward it
• Record body fat, skeletal muscle, and waist on the same screen, or add measurements of your own


MEALS AND NUTRITION

• Log meals as breakfast, lunch, dinner, or a snack
• Build your own food library — save a food once, reuse it in seconds
• Calories in kcal or kJ, plus protein, carbs, fat, and more
• Add your own nutrients if the defaults are not enough


EXERCISE AND ACTIVITY

• Log workouts with duration and calories burned
• Build an exercise library the same way as your foods
• Keep daily steps and activity calories separate from workouts


HABITS AND WATER

• Check off the habits you're working on and build a streak
• Track water intake against a daily target


APPLE HEALTH

• Sync weight, body composition, nutrition, workouts, and water with the Health app
• Choose which categories to share, in either direction
• Turn it off at any time — your records stay in DataBody


PRIVACY

• Your weight, meals, and other health records are never used for advertising
• The app works fully offline. Cloud sync is optional and you choose when to turn it on
• Lock the app with a PIN or Face ID
• Export a backup file you can keep yourself, or a CSV for spreadsheets
