What Calories Journal does
Snap a photo
Point your camera at a plate and get calories and macros in seconds. No database searching.
Or just describe it
Type what you ate in plain language. “Two eggs on sourdough with avocado” is enough.
Scan any barcode
Packaged food resolves against Open Food Facts, a global open product database.
Trends that mean something
A smoothed weight trend, adherence scoring, and macro history — not just today's number.
Streaks that stick
Daily logging with achievements, so consistency becomes the habit rather than the chore.
Your food library
Save the meals you eat often and re-log them in a single click.
Work out your numbers first
Free calculators that use the same equations the app uses to set your daily targets. No sign-up required.
TDEE calculator
Estimate the calories you burn in a normal day, and what to eat to lose, maintain, or gain weight.
BMR calculator
Estimate the energy your body uses at complete rest, using the Mifflin-St Jeor equation.
Food nutrition facts
Calories, protein, carbs, and fat for common foods, sourced from USDA FoodData Central.

Common questions
- Is Calories Journal free?
- Yes. Manual meal logging and logging from your saved foods are unlimited on every tier, and free accounts also get a daily allowance of AI photo and text meal scans. A paid Pro tier removes the daily scan limit.
- Do I need an account to try it?
- No. You can start as a guest and log a few meals without signing up. If you create an account afterwards, everything you logged during the trial moves across automatically.
- How accurate are the calorie estimates?
- Photo and text estimates are produced by an AI model and are approximations, not measurements. They are useful for spotting trends over weeks, not for precise clinical intake. Barcode-scanned products use published values from Open Food Facts, and you can always correct any number by hand.
- How are my daily calorie targets calculated?
- Your basal metabolic rate is estimated with the Mifflin-St Jeor equation, multiplied by a standard activity factor to give total daily energy expenditure, then adjusted for your goal. The full method, including the safety limits applied, is published on the methodology page.
- Does it work on my phone and the web?
- Yes. The same account signs in on both, and your history, goals, and streak stay in sync.
