Smyle AI

Smyle turns your phone's camera into an honest mirror for your smile. Take a quick scan and Smyle reads the cosmetic signals that matter (whiteness, alignment, gum appearance, surface stains, symmetry) and composes them into a single Smile Score from 0 to 100. Your first scan becomes your baseline, and it never changes: every delta and trend you see afterwards is measured against it, from real scans. No inflated numbers, no manufactured progress. A ROUTINE BUILT AROUND YOUR GOAL Tell Smyle what you're working toward, whether that's a whiter smile, healthier gums or fresher breath, and it builds a daily routine of brushing, flossing, whitening, and dentist visits around it. Guided brushing walks you through each zone with a timer; every completed day extends your streak. PROGRESS YOU CAN TRUST Charts show how each metric moves scan over scan, against your baseline. Your goal projection is a simple pace extrapolation and is always labeled as an estimate, because a real number you can act on beats a flattering one you can't. SMYLE AI, GROUNDED IN YOUR NUMBERS Ask the built-in coach why a metric dipped or what to prioritize. It reads only your derived scores and routine, never your photos, and answers in plain language. It won't diagnose; for anything clinical it will tell you what it tells everyone: see a dentist. PRIVATE BY DESIGN Your smile photos stay on your device unless you explicitly choose cloud analysis, and even then each photo is used once over an encrypted connection and never stored or shared. No ads. Your scans and results are never shared with advertisers. Export or delete everything, any time. REMINDERS THAT RESPECT YOU Local notifications on your schedule. Edit or silence them in one tap. Smyle is a cosmetic and habit-building app, not a medical device. It doesn't diagnose or treat anything. For pain, bleeding, or any health concern, see your dentist.
