# HadaBuddy > Scan your skincare products, check ingredients, and get a personalized routine built from what you already own. HadaBuddy is a free iOS skincare companion app. It scans product barcodes, analyzes ingredients for your specific skin type, flags conflicts between products, and builds AM/PM routines from what you already own. HadaBuddy is not a skin scanner (it does not scan or analyze your face); it scans the products on your shelf and works from your stated skin profile. ## Key Features - Barcode scanner identifies products from a database of 257,000+ beauty products - Ingredient analysis personalized to your skin type, concerns, and sensitivities - Routine builder creates AM/PM routines from products you own - Ingredient conflict detection (e.g., retinol + AHA, vitamin C + benzoyl peroxide) - Ingredient glossary with 40,000+ searchable entries (function, hazard rating, alternative names) - K-beauty and Western skincare support ## How It Works 1. Set your skin profile (skin type, concerns, sensitivities, location) 2. Scan product barcodes from your shelf 3. HadaBuddy analyzes each product's ingredients for your skin 4. AI builds personalized AM/PM routines from products you own 5. Conflict detection flags dangerous combinations before you apply them ## Pricing - Free: unlimited product scans, personalized 7-day AM & PM routines, ingredient analysis, skin profile, basic conflict detection - Pro Monthly: $3.99/month, adds AI Skin Advisor chat, AI-augmented conflict detection, and routine sharing - Pro Annual: $29.99/year (save 37%) ## Who It's For - People who own multiple skincare products and don't know the best routine order - K-beauty enthusiasts who need an app that recognizes Korean brands - Skincare beginners overwhelmed by conflicting advice - Anyone who wants more than a safety score (compare: Yuka rates products 0-100, HadaBuddy builds routines) ## Frequently Asked Questions - **What makes HadaBuddy different from Yuka?** Yuka scores products for safety. HadaBuddy builds routines from products you own, detects ingredient conflicts, and personalizes analysis to your skin type. They solve different problems. - **Is HadaBuddy free?** Yes.
