Quick word from your favourite alien. You're no quitter, so let's tick one thing tonight.

See what it looks most like and what's worth doing about it.

A wider part, thinning all over, or after a baby.

After stress, illness or starting a treatment.

Honest guides for when medicine isn't the answer.
Hair recovery is slow. Here's how Roo gets you through it.
Before day one
He asks what a specialist would, shows what your hair loss looks most like and what's behind it, then builds a plan with a reason for every step.
Day 1
Tick your steps, morning and evening. Roo reminds you when you say so. Day one starts on the moon.
Day 3
Three days in a row opens the misty mountain. A week opens the safari. Sixty gets you islands in the sky.
Weeks 2 to 12
Roo has met them all, and he knows what to say to each.
“Skip tonight. One day won't matter.”Two minutes is all it takes.
Tap a monster to hear the others.
Every 4 weeks
A photo set every four weeks, lined up with day one. At month 6, a clear read on how it's going.
Whenever you're curious
Short guides, myth or fact, the newest research, and every treatment graded A to D.
Any time

The treatments are well studied. Keeping them up for months is where most people slip. That part is Roo's job.
86 in 100
At one clinic, 86 in 100 people had stopped minoxidil, most in the first few months.

In a review of 16 trials, text reminders about doubled the odds of people sticking with their medicine.
66 days
In one study, a new daily habit took about 66 days to feel automatic. Each tick is one of them.

Roo's full toolkit from Anagen
No free trial, because the free version is the trial. Your plan, routine and photos stay free for as long as you like. Got a friend's code? Use it when you subscribe and your first month is free.
Payment is charged to your Apple ID when you confirm the purchase. Your subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it any time in Settings › your name › Subscriptions. Prices are in US dollars; the App Store shows the price where you live.
Roo keeps your health to yourself. Here's the short version. The privacy policy has every detail.
Before your first AI use, Roo tells you what is sent and asks your permission. Ask Roo sends your question and a short summary of your plan to Roo's server and on to Anthropic's Claude model. Neither the question nor the answer is stored on Roo's server.
For an AI hair analysis, the photos you choose are sent encrypted and deleted from Roo's servers straight away, and the result is saved on your phone. Anthropic's terms don't allow it to train its models on any of this.
If you join, other members see your display name, picture and posts, or "Anonymous member" when you post anonymously. Every post is checked for safety before it appears.
A progress photo leaves your phone only if you share it yourself, after seeing exactly how the post will look.
Roo never sells data. His server in the EU keeps a random anonymous ID and a few counts so things work. Your health answers and photos aren't among them.
You can delete everything in Settings at any time. This website sets no cookies and has no analytics.
Roo is your coach in the app. He's a small alien from the planet Anagen who looks a lot like a hedgehog and is rather proud of his hair. His people kept theirs with patience and steady days, so he came to Earth to help you with yours. The alien part is for fun. Everything he suggests comes from published research, and he isn't a doctor.
No. Roo is for education and support. His read uses fixed rules drawn from published research to show what your hair loss looks most like and what's worth checking.
Talk to your doctor or pharmacist before starting, changing or stopping any medicine. With Roo Premium, the doctor summary PDF helps you get the most from an appointment.
Yes. Roo asks about hormones, pregnancy, periods and menopause where they matter, and plans for female pattern hair loss and shedding are different from the ones for men. Roo's safety checks take pregnancy into account.
Minoxidil, finasteride, dutasteride, spironolactone, microneedling, medicated shampoos, red light, PRP, natural options like rosemary oil and saw palmetto and, for long-standing hair loss, transplants, hair systems and scalp micropigmentation. Natural-only plans are fine too, with an honest look at how the evidence compares.
Hair grows slowly, so most treatments need months before it's fair to judge, and nobody can promise results. Extra shedding in the first weeks is common with some treatments. Roo shows what to expect at each stage, and your photos let you compare for yourself.
No. Your plan, routine, reminders, widgets, photos, before and after, Learn, reading the community, sharing your progress at milestones and a buddy with friendly nudges are all free. So is your first AI hair analysis.
Roo Premium adds Roo's AI and the community: Ask Roo, the AI hair analysis, the timelapse, photo day in one 7-second video sweep, posting and replying, shampoo scans and the doctor summary PDF. It's $49.99 a year or $7.99 a month.
A fair-use limit keeps it running for everyone: up to 10 questions a day for Ask Roo, and an AI hair analysis twice in any 30 days. The app shows when your next analysis opens. Without Premium, your first AI hair analysis is free.
An iPhone with iOS 18 or later. A few extras, like seeing yourself without hair in the bald mirror, need an iPhone with Face ID.
Yes: give a month, get a month. Share your code from the app. When your friend subscribes with it, their first month is free, and once their Premium starts, you get a month too.
