Food allergies require constant vigilance, and the Food Allergy Scanner - Bokha app available on Google Play offers a practical tool for managing this daily concern. Developed by Alexandre Grisey, this application focuses on helping users identify potentially allergenic ingredients in packaged foods by scanning barcodes. It is free to download and install, though it does contain advertisements and offers in-app purchases for additional functionality. The app has seen a modest number of installs, making it a more niche option compared to mainstream dietary apps.

Scanning a product's barcode brings up a detailed ingredient list with potential allergens highlighted in color. The database contains a wide variety of international products, which I found quite impressive during my testing. Users can customize their allergen profile within the settings, selecting from common triggers like gluten, dairy, or nuts. The app then flags any matching ingredients in scanned products. While the scanning process is generally quick, I did notice that some smaller or local brands were not recognized, which required manual ingredient lookup instead.

Comparing this to apps like Yuka or Open Food Facts, Bokha takes a more focused approach on allergen detection rather than general nutritional scoring. Yuka provides a broader health rating system, while Bokha zeroes in specifically on allergy concerns. The interface feels slightly less polished than some competitors, but the allergen-specific functionality is genuinely useful. For someone who only needs ingredient scanning for allergy reasons rather than overall nutritional analysis, this app fills a specific gap quite effectively.

• The customizable allergen profile is the core feature. Setting up my list of triggers took only a minute, and subsequent scans automatically highlighted any matching ingredients. This saves considerable time compared to reading every label manually. Similar apps often require more configuration or offer less precise filtering.
• Barcode scanning works reliably under good lighting conditions. Holding the phone steady over a package typically brings up results within two seconds. Poor lighting or damaged barcodes sometimes cause failures, but this is common across scanning apps. The product database seems reasonably comprehensive for European and North American brands.
• Manual ingredient lookup compensates for database gaps. When a barcode scan fails on a local product, typing the ingredient list manually still provides allergen analysis. This feature ensures the app remains useful even with unfamiliar products, though it requires more effort than scanning.
• The visual highlighting of allergens on ingredient lists uses clear color coding that makes dangerous ingredients easy to spot at a glance. Red markers for confirmed allergens and yellow for potential cross-contamination risks provide useful differentiation without overcomplicating the display.

• Reduces time spent reading ingredient lists in stores. Quick scans replace several minutes of label examination per product.
• Provides peace of mind when trying unfamiliar brands. Knowing an app has checked the ingredients reduces anxiety about hidden allergens.
• Helps identify unexpected sources of allergens. Some products contain ingredients I would not have recognized as problematic without the app's database.

• Occasional database gaps for smaller or regional brands. Not every product in my local store was recognized, which required manual entry.
• Ads appear between scans and can feel intrusive during rapid shopping trips. The paid version removes these but requires an additional purchase.
• Barcode scanning struggles with curved or reflective packaging. Certain bottles and cans required multiple attempts before successful recognition.
