Folik — AI Coach with Cited Sources + Free Norwood (Our App, Full Disclosure)
Disclosure. Folik is built by Loveiko Labs — the studio publishing this article. We rank it first because that is where its feature set honestly belongs for users who prioritise cited sources, a permanently free Norwood calculator, and calibrated photo journaling.
What it is. A hair loss companion app built around an AI Hair Loss Coach grounded in publicly available content from the American Academy of Dermatology (AAD), the International Society of Hair Restoration Surgery (ISHRS), FDA prescribing information, and 50+ peer-reviewed PubMed studies. Every Coach reply cites its source. Free Norwood/Ludwig calculator with no signup. Calibrated 5-angle photo journal with ghost overlay alignment and pixel-density measurement.
Best for. Users who want every Coach answer cited with a specific source — not "expert guidance" but a named AAD guideline section, FDA document, or PubMed study with year and authors. Users who want the Norwood calculator free with no signup. Users who care about ghost overlay alignment for trustworthy photo tracking. Users on finasteride concerned about PFS who want the honest published evidence framing, not dismissal or catastrophizing.
Strengths. Every Coach reply cites AAD/ISHRS/FDA/PubMed source. Free Norwood/Ludwig calculator permanently free, no signup. Calibrated 5-angle photo journal with ghost overlay alignment. Pixel-density measurement on consistent regions. Explicit off-label disclosure (dutasteride US, oral minoxidil). Explicit FDA Pregnancy Category X warnings. Honest PFS framing. Local-only photo storage.
Limitations. Released May 2026 — newest app in the ranking, smallest installed base, fewest App Store reviews. No in-app product library (Regrow has one). Mature growth-insight charts still iterating. Audience-tested patterns and edge cases still being refined.
