Treatment tracking (minoxidil, finasteride, custom) and daily check-ins
Dated timeline and photo comparisons
Hair Score 0-100 that compares you only with your past self
PDF export for your clinician on every plan
Pro: full history, 90/180-day trends, finasteride/dutasteride side-effect tracking
Keep a consistent photo record while on minoxidil or finasteride
Bring a short dated timeline and comparable photos to a dermatologist visit
Replace mirror-checking and camera-roll searching with weekly sessions

Hi, I'm Leo, the solo maker of Folicle. Checking my hairline in the mirror every day told me nothing, and a camera roll full of photos taken at different angles doesn't help either. Folicle guides you through the same five scalp zones every session, keeps your routine and notes next to the photos, and exports a PDF you can bring to your dermatologist. It is free to start on Android, and iOS has a waitlist. It does not diagnose anything; it just keeps an honest record. I'd love feedback on the photo flow and on what you'd want in the PDF.
