Meals & Food Logging Guide

All the ways to log food — search, scanning, AI analysis, recipes, and more

This guide covers all the ways to log food and track nutrition in Atom Fitness. The new cart-based Food Logger makes it easy to build meals, edit portions, and log multiple items at once.

The Food Logger

The Food Logger uses a shopping cart system — add foods, adjust servings, then log everything with one tap.

Cart Features

  • Add multiple items — Build complete meals before logging
  • Edit in cart — Tap any item to adjust serving size or nutrition
  • Swipe to remove — Swipe left on any item to remove it
  • Undo remove — Accidentally deleted? 5-second undo window
  • Real-time totals — See calories and macros update as you add foods

Progress Tracking

The header shows your daily progress with a visual border that fills as you approach your calorie goal:

  • Calories consumed vs. daily goal
  • Expandable macro breakdown (protein, carbs, fat)
  • Swipe down on the macro panel to dismiss

Adding Food

Multiple ways to find and add food to your cart:

Quick Add & Predictions

The Quick Add tab shows smart suggestions based on your eating patterns.

  • Predicted meals — Foods you typically eat at this time of day
  • Recent foods — Quick access to foods you've logged before
  • One-tap logging — Add directly to cart without opening details
💡
Log at least 10 meals over 3+ days to start seeing personalized predictions.

Food Search

Search our comprehensive database powered by FatSecret with over 500,000 foods.

Search Tips

  • Be specific — "Chobani Greek Yogurt" works better than just "yogurt"
  • Include brands — Brand names help find exact products
  • Use common names — "Chicken breast" instead of "poultry"

Barcode Scanner

Premium Feature — Scan product barcodes to instantly log packaged foods.

  • Tap Barcode in the Quick Add Menu
  • Point your camera at the barcode
  • Hold steady — auto-detection is instant
  • Review and log the product

Database Sources

When you scan a barcode, Atom Fitness searches multiple sources:

  • Verified foods — Curated products with confirmed nutrition
  • FatSecret — Primary database with 500,000+ products
  • Open Food Facts — Fallback for products not in FatSecret
💡
Ensure good lighting and hold your phone 6-8 inches from the barcode for best results. If a product isn't found, you can submit it to help other users.

Nutrition Label Scanner

Premium Feature — Use OCR to read nutrition labels directly from packaging.

  • Frame the nutrition facts label in your camera
  • Tap capture to scan
  • Review and edit extracted values
  • Save for future use

What Gets Extracted

  • Serving size
  • Calories
  • All macros (fat, carbs, protein)
  • Vitamins and minerals (when present)

AI Food Photo Scanner

Premium Feature — Take a photo of your meal and let AI analyze it.

How It Works

  • Take a photo of your food (or select from library)
  • Wait for AI analysis (2-5 seconds)
  • Review detected foods and estimated nutrition
  • Select which items to log

Best For

  • Restaurant meals without nutrition info
  • Home-cooked meals
  • Mixed dishes and plates
  • Quick logging when precision isn't critical
⚠️
AI estimates may vary by ±20%. Use for convenience, not precision tracking.

  • Navigate to Recipes in the Meals tab
  • Tap Create Recipe
  • Add ingredients via search, barcode, or your library
  • Adjust serving sizes for each ingredient

Import from URL

Premium Feature — Import recipes directly from your favorite cooking websites.

  • The app automatically extracts the recipe name, description, instructions, and timing
  • Ingredients are automatically matched to our food database with nutrition data
  • Review matched ingredients and select alternatives if needed
  • Save the complete recipe with accurate nutrition
💡
The ingredient matching uses AI to find the best database matches. You can review each ingredient and select from alternative matches if the suggested one isn't quite right.
