FoodNote - Calorie & Nutrition Tracker

FoodNote is a calorie and nutrition diary built around a large food database. More than 13,000 foods from the USDA FoodData Central database are included, with calories, protein, fat and carbohydrates plus fibre, sugar, sodium, cholesterol, saturated fat and several vitamins and minerals per 100 g, along with common portion sizes.

You log what you eat by meal, and the dashboard shows how much of your daily calorie target remains and how your protein, fat and carbs compare with your goals. You can also log water and body weight, save your own foods, build recipes and save meal sets you eat often.

It suits anyone who wants to understand what they eat — people managing their weight, athletes watching protein, or anyone curious about sugar or sodium — without creating an account. Everything you log stays in your browser.

How to use FoodNote

  1. Set your goals. On first use, or later under Goals, enter your details and choose to lose, maintain or gain weight. FoodNote suggests a daily calorie target using the Mifflin-St Jeor equation and lets you adjust calories and macros yourself.
  2. Add a food to a meal. On the dashboard, tap + next to breakfast, lunch, dinner or a snack. Type a food name in English, such as "banana" or "oatmeal", and pick a result.
  3. Choose the amount. Select a portion (100 g or a listed household portion) and the quantity, check the nutrition preview, then save. The dashboard updates immediately.
  4. Reuse foods quickly. The History and Favourites tabs in search list foods you have logged before. Save your own items under My Foods, combine ingredients into recipes, or save a meal set to log several foods at once.
  5. Log water and weight. Use the water card on the dashboard to add glasses, and the Weight screen to record your weight and see the trend.
  6. Review statistics and export. The Statistics tab shows average calories and macros and charts for a week, month, three months or a year. In Settings you can download a CSV export or a backup file and restore it later.

Features

Reading calories and macros without overthinking it

Where calorie targets come from

Your body burns energy at rest (basal metabolic rate, BMR) and more through daily activity and exercise. The Mifflin-St Jeor equation estimates BMR from weight, height, age and sex; multiplying it by an activity factor gives total daily energy expenditure (TDEE). Eating about 500 kcal below TDEE is a common starting point for gradual weight loss, and about 500 above for gaining. These are estimates — real needs vary, so watch your weight trend over several weeks and adjust.

The three macronutrients

Protein and carbohydrates provide about 4 kcal per gram and fat about 9 kcal per gram (alcohol about 7). Protein supports muscle and keeps you full; many adults aim for roughly 0.8 g per kilogram of body weight, and active people often more. Carbohydrates are the main fuel for exercise, and fibre — a type of carbohydrate — supports digestion; adult guidelines are often around 25–38 g of fibre a day. Fat is essential for hormones and absorbing vitamins A, D, E and K.

Weighing and portions

Database values are per 100 g of the food as described, so "raw" and "cooked" entries differ a lot: cooked rice and pasta absorb water and have fewer calories per 100 g than dry. A kitchen scale gives the most accurate log; household measures like cups and slices are convenient but less precise. Oils, dressings and drinks are easy to forget and can add up quickly.

Using the numbers sensibly

Day-to-day logs are never perfect; consistency matters more than precision. Look at weekly averages rather than single days, and remember that body weight naturally fluctuates by a kilogram or more because of water and salt. If tracking makes you anxious, or if you have diabetes, kidney disease, are pregnant or have a history of disordered eating, talk to a doctor or registered dietitian before setting targets.

Frequently asked questions

Is FoodNote free in the browser?

Yes. Searching foods, logging, goals, water, weight, statistics and export work without an account.

Where is my data stored?

Only in this browser on this device (IndexedDB). Nothing is uploaded. Clearing site data for this website or using a private window deletes your log, so download a backup from Settings now and then.

Can I search in my own language?

On the web, food names are searched in English, the language of the USDA database. The phone app can translate searches on the device.

Where does the nutrition data come from?

The built-in foods come from USDA FoodData Central. Online results for packaged products come from Open Food Facts, a community database; check labels for exact values.

Can I scan barcodes?

Barcode scanning with the camera is available in the iPhone and Android app. On the web you can add packaged foods as custom foods with the values from the label.

How is the web version different from the phone app?

Logging and statistics are the same. The app adds barcode scanning, multilingual search and an optional ad-free upgrade; purchases are not available on the web. Data is not shared between the app and the browser, but you can move it with a backup file.
