How to Use FoodScreener

Welcome to FoodScreener!

No more trying to read tiny ingredients lists in the store! Learn how to use FoodScreener to scan and evaluate food products based on your preferences.

Ideally, we’d all have time to prepare our meals at home using natural ingredients. But time is short, and carefully selected packaged foods let you have healthy meals ready quickly. Use FoodScreener to find the best packaged foods for your needs.

Step 1: Scan Barcodes

📱 Start Scanning

Tap the "Scan" button on the Home screen to open the barcode scanner. Point your camera at any product barcode and hold steady, or bring camera closer to barcode.

When the barcode is scanned, you'll hear a click and see the results.

💡 Tip: Store-printed barcode labels usually won't work well. Use the manufacturer's original barcode on the packaging.

Step 2: View Results

📊 Understand Your Results

After scanning, you'll be taken to the Product screen to see details about the product including ingredients and if it matches your preferences.

If the product does not match, the reason is displayed below the product photo, or you can tap on the 'traffic light' display to see a more detailed matching evaluation.

🟢 GO - Matches your preferences

🟡 CAUTION - Partial match

🔴 STOP - Does not match

Step 3: Set Your Preferences

⚙️ Customize Your Dietary Needs

Go to the Preferences tab to set up your dietary restrictions, allergies, and food values.

How to set preferences:

100% - Critical requirement (must have/avoid)
0% - Don't care about this preference
In between - Moderate preference

⚠️ Important: For life-threatening allergies, always double-check the ingredients list on the product label. FoodScreener is helpful but should not be your only source for critical allergy information.

💡 Pro Tip: The app works best when you leave most preferences at 0% and only set the ones that really matter to you.

Step 4: Check Your Scan History

📚 Review Previous Scans

Your previously scanned products appear on the Home screen, making it easy to check items you've scanned before.

Just tap any item line to see the full product page with all details.

This helps you:

Remember products you've already checked
Compare similar products
Share findings with family members

You’re All Set! 🎉
