ost diaper comparison sites lie. They ignore complex coupon mechanics and show fake prices. Diaperoo is different: it’s a smart coupon engine calculating the true effective price per diaper. Standout features: • Pro-rata calculation (accurately splitting a €6 discount across a 4-pack minimum) • Smart exclusion rules • 1-click deep-links to activate coupons instantly in-app. Don't do the math at 3 AM. Let Diaperoo find the real best deal.

Hi Product Hunt! 👋 I'm Hendrik, the maker of Diaperoo. If you're a parent, you know the struggle: buying diapers is surprisingly complicated. Existing comparison sites just take the box price and divide it by the diaper count. But that's not how reality works. We use loyalty apps, "Buy 2 get 1 free" deals, and complex coupons. I got tired of doing the math at 3 AM, so I built Diaperoo. It’s not just a scraper; it's a smart coupon engine that calculates the true effective price per diaper. Here is what makes it different: 🍼 Pro-rata math: It correctly splits volume discounts across the required amount of packs. 🛡️ Fake-deal shield: It actively filters out wipes and swim diapers that mess up the algorithms of other sites. 📱 App deep-links: Found a deal? One click opens the official drugstore app so you can activate the coupon instantly. I built this using Supabase and TanStack Start and learned a lot about edge-case handling along the way. I'd love to hear your feedback! Are there any features you're missing? Happy to answer any questions about the product or the tech stack. Let me know what you think! Cheers!
