The app

A calorie counting app
that reads the whole meal.

Start with a camera, gallery image, nutrition label, barcode, text, voice, favorite, or Quick Log. Correct the ingredients and portions once, then use the same meal for calorie and macro goals, ingredient-level protein, longer trends and. Where data exists, FODMAP, GI, and GL.

Eight ways to start a meal log

Use the fastest path for the moment. Every route lands in one meal history you can review and improve.

  1. 01 Camera

    Photograph the plate, then review the recognised foods and estimated portions before saving.

  2. 02 Gallery

    Use a meal photo you already have and turn it into the same editable food record.

  3. 03 Nutrition label

    Photograph a printed label, confirm the serving, and keep the packaged meal in your history.

  4. 04 Barcode

    Look up packaged-product data and keep its source, licence, and product link when the provider supplies them.

  5. 05 Text

    Describe the meal in your own words, then check the foods and quantities the app understood.

  6. 06 Voice

    Say what you ate when typing is inconvenient, then review the recognised meal.

  7. 07 Favorite

    Bring back a meal you repeat often without rebuilding it ingredient by ingredient.

  8. 08 Quick Log

    Capture the meal and time immediately when speed matters more than a detailed analysis.

What comes back

Energy and macros
Review calories, protein, carbohydrate, and fat for the meal and day against targets you can edit.
Protein that leads to a next step
See which ingredients supplied the protein, follow the longer trend, and use the next-meal need and fitting favorite suggestion.
FODMAP categories
When enough data exists, the app shows a low, moderate, or high meal flag and highlights ingredients marked as higher-FODMAP.
GI and glycemic load
When available, GI appears beside a glycemic load that changes when you correct the logged portion. Neither predicts your personal glucose response.
Trends, Food Reviews, and PDF
Move from today to 7- and 30-day patterns, then open weekly or monthly Food Reviews and keep a completed review as a PDF.

Built for action, not just logging

  • Make the draft yours. Add missing foods, correct ingredients, and adjust quantities so the saved meal reflects what you actually ate.
  • See the effect of a correction. Calories and macros update with quantity, and glycemic load follows the corrected portion whenever GI data exists.
  • Turn days into a review. Food Reviews organise the longer pattern, surface data coverage, and create a PDF you can keep or bring to a nutrition conversation.
  • Know where packaged data came from. Barcode records retain the source, licence, and product link whenever the provider makes them available.

Questions people
actually ask.

Straight answers about calorie tracking and how 3sense Food works.

Can an app really count calories from a photo?

Yes, as a fast, editable estimate. 3sense Food recognises visible foods, suggests portions, and calculates calories and macros; you can add hidden ingredients and correct quantities before the meal feeds your goals, trends, and Food Reviews.

Is 3sense Food free?

It is free to start on iPhone and Android, and the glycemic load calculator on this site is free and needs no account at all. This site, the App Store and Google Play show what the paid Food Premium tier currently includes.

How accurate are AI calorie counters?

Their practical value comes from speed plus correction. Start from a clear photo, then fix the portion or use barcode and label data for packaged foods. Each correction updates the meal and makes the longer 7- and 30-day pattern more useful.

Does it work for a low FODMAP diet?

It supports the food-recording side with low, moderate, or high meal flags, higher-FODMAP ingredients, fibre, and 7- or 30-day low-FODMAP adherence when enough data exists. Pair that structured food history with symptom notes and a qualified dietitian for elimination or reintroduction.

What makes it different from other calorie counting apps?

Eight input modes lead into one editable meal history. You can see protein by ingredient, an editable calorie and macro plan, 7- and 30-day trends, FODMAP, GI and portion-aware GL where data exists, plus weekly or monthly Food Reviews and PDF. Barcode records also retain source, licence, and product link when supplied.

Do I need to weigh my food?

No, and most people should not start there. Photograph the plate, correct the estimate when it is obviously off, and weigh only the staples you eat often. Consistency beats precision: a method that is roughly right and gets used daily beats a precise one abandoned in week two.

One meal. More useful context.
