Track the treatment.
Trust the photos.

No. There is no server to upload to. Photos, treatment logs, and settings live in the app's storage on your phone, and the App Store privacy label is "Data Not Collected". The one optional network feature - a WiFi scalp microscope - streams video into your phone over your local network; nothing flows out.

Same lighting, same angle, same distance - every time. That is the whole trick, and it is what Norwood automates: the scalp map frames each of the six regions with its own camera and angle hint, so this month's photo matches last month's. Even lighting and a consistent hairstyle help too.

Monthly is enough for most people. Hair change is slow, so a consistent monthly photo of each region beats daily snapshots taken at different angles in different light. Norwood's recency dots show which regions are due, and photo day takes a few minutes.

No, and it doesn't try. Norwood has no AI score and gives no verdicts - lighting and photo conditions make automated judgments unreliable, and a diagnosis belongs with a dermatologist. What Norwood gives you is evidence: aligned photos taken months apart that show what memory can't.

Yes - that is one of the best uses. Dated, region-labeled, consistently framed photos are exactly what clinicians ask for when assessing change over time. Bring your phone to the appointment, or export a backup zip; nothing needs to be uploaded anywhere.

Yes. Log any routine you and your clinician chose - a topical such as minoxidil, microneedling, supplements - and Norwood reminds you at the times you set and shows your adherence next to your photo timeline. Norwood documents your routine; it does not diagnose, treat, or promise results.

It is named after the Norwood scale, the seven-stage scale doctors use to describe male-pattern hair loss. The app does not assign you a stage - no scoring, no verdicts. It gives you consistent, dated photos so you and, if you choose, your doctor can judge for yourselves.

Export a backup first: Settings > Export backup produces a single zip with every photo, thumbnail, and log, handed to the system share sheet. Save it wherever you trust, then restore it on the new phone. Norwood never does this for you in the background - a backup only exists if you make one.

No. Norwood is a journal, not a doctor. It does not diagnose, treat, cure, or prevent anything, and it does not give medical advice. It keeps an honest photographic record and reminds you of the schedule you chose. For medical advice, see a qualified professional - and bring your photos.

iPhone (iOS 16.4 or later) and Android (7.0 or later). The full treatment-tracking experience - adherence, streaks, the daily ring - is currently iPhone-first; on Android, Norwood offers the photo journal, comparisons, and general reminders. Both versions also support an optional WiFi scalp microscope: magnified close-ups with follicle-level detail a phone camera can't resolve, so subtle month-over-month change is easier to see (how the microscope method works). No microscope is required - the phone camera covers everything else.

Norwood is free. There are no ads, no subscriptions, and no in-app purchases.

Because they are verifiable: the app declares "Data Not Collected" on the App Store, requests no tracking permission, and ships no analytics or advertising SDKs. The only network code it contains connects to a scalp microscope on your local network - there is no code that talks to any server. The same goes for this website: no cookies, no advertising, no cross-site tracking - the only measurement is cookieless, aggregate page counts that cannot identify you. Details in the privacy policy.
