Liam Vang, a 14-year-old from Cabarrus County, has launched AllerScan, a new smartphone app helping people manage food allergies with ease.
The app, now available on the Apple App Store and coming soon to Google Play, allows users to quickly scan product barcodes and check for allergens.
Inspired by his own struggles with a peanut allergy, Vang created AllerScan to simplify the often stressful process of checking food labels.
Users customize their profiles with specific allergens; scanning a barcode instantly reveals if a product is safe to eat.
The app even offers directions to the nearest emergency room if a risky product is detected.
Vang’s innovation joins Charlotte’s growing movement toward allergy-friendly options, such as Seemingly Overzealous in Dilworth and groups like Parents of Allergic Kids (PAK).
His work is creating a safer, more inclusive community for those with food allergies.
