Skin Tracker: Photo Journal

Skin Tracker is a private, local-first photo journal designed to help you organize skin photos, log notes, and observe subtle changes over time.

Keep a secure visual record of skin changes, texture marks, irritation, cosmetic progress, skincare routines, or any other skin area you want to track—fully offline and under your control.

IMPORTANT: Skin Tracker is an observational journal. It does NOT provide medical advice, evaluate skin conditions, or identify specific medical concerns. If you are concerned about a spot or change, consult a healthcare professional immediately.

WHY USE SKIN TRACKER?
Ordinary photo albums get lost in your camera roll, and basic reminders don't link to specific locations. Skin Tracker is purpose-built to organize your observations in one private space, making it easy to prepare for your next dermatologist or doctor visit.

CORE FEATURES:
• Secure Spot TIMELINES: Create entry profiles for specific spots on your body to view their individual chronological progression.
• Precise Anatomical MAPPING: Mark where each entry is located using a simple anatomical model map, so you always know exactly which photo belongs where.
• Side-by-Side COMPARISON: Compare photos from different dates side-by-side to observe visible differences in size, color, shape, or appearance.
• Reference-Based MEASUREMENT: Measure visual areas using a known-size reference object in the photo (like a coin). Mark the reference, enter its real-world size, and the app calculates dimensions directly.
• Entry Notes & Symptom LEVELS: Add written notes and log manual severity levels for itchiness, redness, discomfort, flaking, swelling, or bleeding.
• Flexible REMINDERS: Set custom check-in schedules globally or for specific spots.
• Clinician-Ready EXPORTS: Generate a professional, clean PDF summary of your observations and timelines to share directly with your doctor.

PRIVACY & SECURITY FIRST:
• Local-First Storage: All photos and notes stay on your device. We do not use external tracking scripts, require user accounts, or upload data to a server.
• Optional Encrypted Backups: Secure your data with device-native backups or optional end-to-end password-encrypted photo backups.
• Separated Gallery: Keep your sensitive skin photos completely separate from your personal device camera roll.
