SkinArc: Skin Diary & Tracker

SkinArc turns your daily selfie into real data. One guided photo a day is all it takes for SkinArc to measure redness, pores, fine lines, dark circles, and spots -- no filters, no guessing. Every score comes from a deterministic on-device algorithm, not an AI's subjective impression, so your trend lines actually mean something. FREE INCLUDES - Daily guided capture with lighting and angle checks - Trend tracking for 5 core skin metrics - 14-day trend chart - Change replay: your own daily photos played back in order (after 5 days of photos) - One free AI weekly report (from day 7) - Log one skincare change and see its before/after comparison - Local storage -- photos never leave your device unless you turn on sync - Guest mode -- try it with no account required - Available in 8 languages: English, 中文, 日本語, 한국어, Français, Deutsch, Italiano, Español - Full dark mode VIP UNLOCKS - 7 additional metrics: oiliness, tone evenness, texture, broken capillaries, dullness, breakouts, blackheads - Track multiple skincare changes at once (a new serum, retinol, a diet change...) -- each with its own independent before/after stats. Not marketing copy, an actual data receipt. - Weekly and monthly AI-written deep-dive reports - Automatic environmental correlation -- see whether UV, humidity, or air quality lines up with your skin's changes - 2-4 capture reminders a day, timed to follow your schedule - Cross-device cloud sync - Daily AI tip PRIVACY FIRST Photos are stored locally on your device by default and are uploaded only if you turn on cloud photo sync. If you sign in, your scores and logged changes sync so the app works across devices. The app calls an AI in two optional places, the written report and the daily tip, and both receive text only (your scores, the name of a change you logged and, for the tip, local weather), never your photos. NOT MEDICAL ADVICE SkinArc tracks statistical patterns in your own personal data. It does not diagnose anything and is not a substitute for a dermatologist's professional judgment. An optional App Lock (PIN + biometrics) keeps your photo library private if someone else picks up your phone. $5.99/month or $39.99/year. Cancel anytime in App Store settings.
