Trend found
Sleep and mood scores appear to move together — lower sleep precedes lower mood by 1–2 days.

"I know something is off.
I just can't explain it to my doctor."

The sentence in every third post in every perimenopause community online. Peryn gives you something to show.

How it works

Sixty seconds a day.
Months of evidence.

Peryn is built around a daily habit that compounds. The more you log, the clearer your trends become — and the more useful the doctor visit summary gets.

01

Log how you feel

Six dimensions, scored 1–5. Sleep quality, brain clarity, mood, energy, body temperature, and interest in intimacy. Plus an optional note for context — "stressful week", "started a new supplement". Takes about a minute.

Daily · 60 seconds
02

Your data tells a story

Peryn looks at your scores over time and surfaces what your data shows — things like "your mood scores tend to follow your sleep scores by 1–2 days" or "your energy has declined over the past month". Observable trends, nothing more.

Weekly · AI-powered
03

Bring receipts

Generate a plain-English doctor visit summary PDF — 30, 60, or 90 days of your data, organised. Trend charts, your own notes, suggested conversation starters. Put it in front of your doctor. Stop trying to explain. Start showing.

About Peryn

Built for someone
we love.

Peryn started with someone close to us who spent years knowing something was wrong but couldn't explain it to her doctors. She had the words. She just didn't have the data.

She would leave appointments with normal bloodwork and a vague suggestion to sleep more. What she didn't leave with was answers — or even acknowledgment that what she was describing was real.

Peryn was built to give her — and women like her — something to point to. Not a diagnosis. Not a treatment plan. A record. A trend. A PDF she could put on the desk and say: look at this.

We are a small, independent product. We are not a VC-backed company with a marketing department. We are not a telehealth platform. We are not a medical device. We are a tool built for one specific, overlooked problem: the gap between how a woman feels and what she can prove.

Important — please read

Peryn is a general wellness tracking app, not a medical device. It is not regulated by the FDA, MHRA, TGA, or any equivalent health authority. Nothing Peryn generates — including AI trend summaries and doctor visit PDFs — constitutes medical advice, clinical diagnosis, or treatment recommendation. Always consult a qualified healthcare provider for any health concern.

Your data is yours
We never sell your data. We never share it with advertisers, insurers, or employers. We never use it to train AI models. You can download everything you've ever logged, and you can delete your account — and all associated data — permanently, any time.
We stay in our lane
Peryn never diagnoses. Never recommends treatments. Never suggests supplements. The moment we do any of that, we become something we are not — and something that could cause harm. We describe what the data shows. Nothing more.
Built for the long term
Perimenopause can last a decade. The trends that matter most emerge over months and years, not days. Peryn is designed to be useful at day 7 and indispensable at day 365. The longer you track, the more valuable the data becomes.
International from day one
Peryn is built for US, UK, EU, Canadian, and Australian users from launch. GDPR, CCPA, PIPEDA, and Australian Privacy Act compliance is built into the product — not bolted on later. Your rights are respected regardless of where you are.
FAQ

Questions we
actually get asked.

No. Peryn is a general wellness tracking app. It is not a medical device, not regulated by the FDA or any equivalent health authority, and nothing it generates constitutes medical advice. The doctor visit PDF is a communication tool — it helps you describe your trends to a physician, not replace that conversation. Always consult a qualified healthcare provider for any health concern.
It looks at your self-reported scores over time and surfaces what your data shows — correlations between dimensions (like sleep and mood moving together), trends (improving, declining, stable), and notable periods. It describes what the data shows, nothing more. It does not diagnose conditions, suggest treatments, or imply medical authority. Every output is reviewed against a strict guardrail — if something sounds like medical advice, it gets removed before it reaches you.
Only you. Your data is stored with row-level security — no other user can access your logs under any circumstance. We never share your health data with advertisers, data brokers, or third parties. When your data is processed by our AI, it is anonymised — only scores and timestamps are used, with no identifying information attached. We do not use your data to train AI models. Full details are in our Privacy Policy.
You keep full access until the end of your billing period. After that, your account is locked — but your data is kept securely for 60 days. If you resubscribe within that window, everything picks up exactly where you left off — every log, every trend, your full history. After 60 days, your account and all data are permanently deleted. You'll receive a reminder before that happens.
No. Many users start tracking precisely because they suspect something is changing but don't have a diagnosis — and can't get one, because the data doesn't exist yet. Peryn helps you build that data. Research shows that perimenopause symptoms can begin in the mid-thirties. You don't need a label to start tracking what you notice.
That's what we built it to be. It's designed to be handed to a physician — clear, plain-English, with a mandatory disclaimer that makes the wellness-only framing explicit. Early users have reported that bringing the PDF changed the nature of their appointments: less time spent trying to explain from memory, more time discussing trends the doctor could actually see. We continue to collect these stories and they shape how we develop the PDF further.
Peryn is available in the United States, United Kingdom, European Union, Canada, and Australia / New Zealand from launch. Privacy compliance (GDPR, CCPA, PIPEDA, Australian Privacy Act) is built in for all supported regions. Pricing is in USD — local currency conversion is handled at checkout.
Peryn is a Progressive Web App (PWA) — you add it to your home screen directly from your browser, with no App Store required. It works on iOS and Android, loads offline, and supports push notifications for your daily reminder. It behaves exactly like a native app. We plan to evaluate native App Store distribution in the future, based on user demand.
Peryn is new. The price today — $19/month or $149/year — is the lowest it will ever be. As the product grows, we'll raise prices for new subscribers. But if you subscribe now, your rate is locked in permanently. No catches, no expiry. If you're on a monthly plan and we raise prices next year, you keep paying $19. That's the founding member guarantee.
