Hi Product Hunt community! I’m Michal, the maker behind AllergApp. The inspiration: I’ve always felt that grocery shopping with allergies or dietary restrictions is unnecessarily stressful. Customers often spend more time reading labels than actually shopping. I wanted to change that by making the process "invisible" and automated through technology. The problem we are solving: For retailers, an allergy often means a lost sale. If a customer can't find a safe version of a product, they leave. AllergApp’s API turns this friction into an opportunity. We don't just detect allergens; we instantly suggest 'Healthy Swaps'—safe alternatives from the retailer’s own private labels. Why it’s different: We focused heavily on performance. Our engine handles over 3,000,000 items with latency under 300ms, making it fast enough for real-world retail apps and high-traffic e-commerce. I’d love to hear your thoughts: How do you currently manage dietary restrictions when shopping? What other features would make your shopping experience safer? I'll be here all day to answer any technical or business questions. Looking forward to your feedback!
