HadaBuddy - Scan your skincare. Get a routine built from what you own.

Hey PH 👋 I'm Novia, founder of HadaBuddy. I have 23 skincare products on my shelf. Most I bought because someone on TikTok said I needed them. Yuka tells me if each one is "safe" but not what to actually *do* with them. Should I use the niacinamide before or after vitamin C? Will the retinol fight the BHA? Is this $40 essence cancelling out the $30 serum? I built HadaBuddy as the app I wished existed: • Scan any barcode → ingredient analysis personalized to your skin • Build a 7-day AM/PM routine from products you already own • Get warned before mixing things that fight each other (retinol + AHA, vit C + BP, etc.) • 200,000+ products, full K-beauty support (COSRX, Anua, Beauty of Joseon, Laneige…) The free tier covers unlimited scans, ingredient analysis, conflict detection from a curated rules DB, and up to 5 AI-generated routines per day. Pro ($3.99/mo, $29.99/yr) adds: - AI Skin Advisor chat for follow-up questions - AI-augmented conflict detection (catches novel conflicts beyond the rules DB) - Unlimited routine regenerations - "Why this order?" explanations + weekly overview 7-day free trial on Pro. Scan + analysis + basic conflict detection are 100% free, no time limit. I'd love feedback from anyone who: - Has more skincare than they actually use - Has been confused about layering order - Has had a bad reaction from mixing products Honest critique especially welcome. What's missing? What's confusing? What doesn't work? 🍎 apps.apple.com/app/hadabuddy/id6761774731 🌐 hadabuddy.com Thanks for taking a look 🧴 Novia
