Perimenostage VS GitHub Surf

Perimenostage's answer

Next.js (React) web app installable as a PWA with push notifications, Stripe for payments, Umami for privacy-friendly analytics, Nginx, and a content pipeline that builds symptom and guideline pages from structured, source-referenced JSON.

Perimenostage's answer

Perimenopause can start years before the last period, yet most women first hear the word after months of symptoms that nobody connected. In a 2026 study from Mayo Clinic and Flo, 83% of women 35 and older reported fatigue linked to the transition. Visits are short, symptoms come and go, and patients arrive without data.

We looked at what was available. Trackers collected data but never turned it into something a doctor could use. Content sites were written to sell supplements. Telehealth brands led with prescriptions. Perimenostage was built to fill the gap in between: a clear stage check, daily tracking that ends in a usable report, and content where every claim is sourced. The books came later, when it became clear that partners needed the same briefing.

Perimenostage's answer

Women aged roughly 38 to 55 in the US who notice changes they can't explain yet: broken sleep, night sweats, irregular periods, brain fog, anxiety or rage that wasn't there before. Many have already been told "it's just stress" or "you're too young for menopause." They are not looking for a miracle product. They want to understand what is happening and get taken seriously by their doctor.

A second audience is their partners, who want to help but were never told what perimenopause is.

Perimenostage's answer

Most menopause apps either track symptoms or sell something: supplements, telehealth visits, hormone prescriptions. Perimenostage does neither. It turns daily check-ins into a doctor-ready report every 30, 60 and 90 days, so the user walks into her appointment with symptom trends instead of a vague memory of the last few weeks.

Every page and every number is checked against named studies and US clinical guidelines: The Menopause Society, ACOG, NIH and the SWAN study. Sources are listed on the page, so a reader or a clinician can verify them. The free Stage Finder places symptoms on STRAW+10, the staging system clinicians actually use, not on an invented scale.

Perimenostage's answer

• It is built for the appointment, not for endless tracking. The 30/60/90-day report is the output, and the tracking exists to feed it.
• No product to push. We don't sell supplements or prescriptions, so nothing in the content is written to steer you toward a purchase.
• Evidence labels instead of opinions. Options are ranked from strong evidence to not recommended, with the source next to each claim.
• It starts free. The Stage Finder quiz costs nothing. The full app is $1 for 7 days, then $99/year, with a 30-day money-back guarantee.
• It covers the whole household. A partner's guide and a symptom atlas extend the same evidence-based approach beyond the app.
