Skincare Tracker Skin Journal

Know exactly what is working for your skin — and what is not.

Skincare Tracker is an offline-first, private skin journal. Log products, build routines, photograph your skin daily, and get AI-powered advice built from your own data. Nothing leaves your device. No account required.

DAILY SKIN LOG
Take a daily photo and rate your skin condition (1-5). Track 12 concern types including acne, dryness, oiliness, sensitivity, redness, dark spots, and wrinkles. Weather data — temperature, humidity, and UV index — is recorded automatically. Compare any two entries side by side to see real change over time.

PRODUCT LIBRARY
Add products by scanning a barcode or entering details manually. Organize across 13 categories including cleanser, moisturizer, serum, toner, and sunscreen. Track expiry dates (PAO), note patch test results, log pH and active ingredients, and flag sun sensitivity. Never accidentally use expired SPF again.

ROUTINE BUILDER
Create morning, evening, weekly, or custom routines with ordered steps. Each step links to a product in your library, includes custom instructions, and supports wait times between layers. Run a step-by-step routine player with a countdown timer so each active absorbs properly. An ingredient conflict detector warns you before combining incompatible actives such as vitamin C and niacinamide, or retinol and AHAs.

PROGRESS AND ANALYTICS
View mood trend charts, skin concern breakdowns, and daily consistency scores. Compare before-and-after photos. Export a full PDF skin report to share with your dermatologist (Premium).

STREAKS AND ACHIEVEMENTS
Build a daily logging streak and earn milestone achievements as your habit grows. Cycle tracking provides phase-specific skincare tips.

DAILY REMINDERS
Scheduled push notifications remind you to log your skin and complete your routine so you never miss a day.
