SkinTrack

SkinTrack helps you monitor moles, spots, and skin lesions over time — entirely on your device. No account required. No data ever leaves your phone.

📸 PHOTO TRACKING
Capture close-up photos of any skin spot and revisit them side-by-side over
weeks and months. Ghost overlays help you align repeat photos perfectly so changes are easy to spot.

📏 DEPTH MEASUREMENT
On supported devices, SkinTrack uses your phone's depth sensor to measure the physical size of a lesion — width, height, and surface area in millimeters — at every visit.

🔒 COMPLETE PRIVACY
• All photos and data stay on your device
• No user account or sign-in required
• No cloud backup or sync
• No ads, no data selling, no third-party sharing
• Works fully offline

📋 DETAILED OBSERVATIONS
Log notes, colors, borders, symmetry, and any changes you notice. Build a timeline for each spot so you arrive at your dermatologist appointment with clear, organized history.

🆚 BEFORE & AFTER COMPARISON
View any two photos from your history side-by-side with synchronized zoom and pan. See exactly what has changed and share a comparison image with your doctor.

⚕️ MEDICAL DISCLAIMER
SkinTrack is a personal tracking tool — it cannot diagnose skin conditions or replace professional medical advice. If you notice a change that concerns you, consult a dermatologist promptly.

💚 NOT-FOR-PROFIT
SkinTrack is free to use with no required subscriptions. Optional tips help keep the app maintained for everyone.
