What is AI Food Scanning?

Kaloria's AI camera uses advanced computer vision to automatically identify foods in your photos. Instead of searching databases and typing, just snap a picture—our AI instantly recognizes foods, estimates portions, and calculates complete nutrition data.

The scanner can identify:

  • Individual foods- Apple, chicken breast, bowl of rice
  • Complete meals- Complex dishes with multiple ingredients
  • Restaurant meals- Popular menu items and dishes
  • Home-cooked dishes- Recipes and homemade meals
  • Multiple items- Several different foods on one plate

Position Your Food

Center your meal within the scanning frame. For best results:

  • Show the entire dish in the frame
  • Use good lighting - natural light works best
  • Hold camera at 30-45° angle, not directly above
  • Avoid shadows covering the food
  • Get close enough to see details

Scanning Barcodes on Packaged Foods

For packaged foods with barcodes, Kaloria can instantly pull exact nutrition data from global food databases. This is even more accurate than AI photo recognition for labeled products!

How to Scan a Barcode:

  1. Open the camera (same as above)
  2. Point the camera at the product's barcode (UPC or EAN)
  3. The barcode is detected automatically - no button to press!
  4. An overlay appears showing the product name and nutrition per 100g
  5. Tap anywhere outside the overlay to dismiss it and proceed to take a photo
  6. The AI will use the barcode data to enhance its analysis

Barcode Scanning

Barcode Database

Kaloria uses OpenFoodFacts, a global database with millions of products. If a barcode isn't found, the AI will still analyze your photo—just without the barcode data boost.

Other Camera Options

The camera screen has several handy shortcuts:

Gallery Picker

Select an existing photo from your device to analyze. Great for photos you took earlier or received from others.

Manual Text Entry

Describe your food in text instead of taking a photo. Just type "grilled salmon with asparagus" and get nutrition data.

Recent Meals

Quickly re-add meals you've logged before. Perfect for recurring meals or favorite dishes.

Camera Flash

Toggle flash on/off for low-light situations. Better lighting improves AI accuracy!

Tips for Maximum AI Accuracy

Photography Best Practices
  • Natural Light:Daylight or bright indoor lighting gives best results
  • 45° Angle:Not directly overhead - angle helps AI see depth
  • Show Everything:Capture the full portion, don't cut off parts
  • Plain Background:Reduces distractions for AI
  • One Plate at a Time:Better results than multiple plates
  • Stay Focused:Avoid blurry photos

Common Issues & Solutions

Check that Kaloria has camera permissions in your device Settings → Privacy → Camera. Force close the app and restart. Make sure no other app is using the camera.
Check your internet connection - AI analysis requires internet. Try switching between Wi-Fi and mobile data. If it times out, retake the photo or use manual entry as an alternative.
Use the refine feature to give the AI more context. Adjust the serving size dial. You can also edit nutrition values after adding to journal. For very unique dishes, manual entry might work better.
Free users get 10 scans per day. You can still use manual text entry, barcode scanning, and recent meals (all unlimited). Your scan count resets 24 hours after your first scan. Upgrade to Premium for unlimited scanning.
Yes! Kaloria can identify multiple foods in a single photo. Make sure all items are clearly visible and well-lit. The AI will detect and list all components with individual nutrition data.
Photos are stored privately on your device and in your personal Kaloria account. They're never shared publicly or sold. You can delete photos anytime from your journal. We only use photos to provide AI analysis and display in your private food diary.
