Maren is a cycle and symptom tracker for perimenopause that doesn't pretend it can predict you. It just helps you see what your body is actually doing — and brings the proof to your doctor.
You're not late. Your cycle is changing. But the app treats every shift like an error and pings you about it.
That calendar hasn't been true for a year. Predictions built on an average you no longer have are just confident guesses.
Brain fog. Joint aches. 3am wakeups. The new, strange ones — and there's nowhere to log them, let alone make sense of them.
Maren won't force a 28-day model or call you "late." It shows you what's actually happening over weeks and months, so the shifts stop feeling random.
Forty-plus things that actually change in these years — and room to add your own. Then Maren connects the dots: the hot flushes that cluster after a bad night's sleep, the mood dip that tracks a short cycle.
Turn months of logs into one clear summary you bring to your appointment. Not a diagnosis — your own history, organized, so the conversation starts from facts instead of "I think it's been a while."
Your most personal data shouldn't be a product. Maren is built so your records stay yours — never sold, never handed to advertisers. (You may have read what happened when another period app didn't hold that line.)
We're putting this here before we've written a line of the app — because if we can't build it to keep these promises, we'd rather not build it.
We're building Maren with a small founding group. Reserve your spot with a fully refundable $5 deposit — it comes off your first year, and your founding price never goes up.
I built Maren because I watched the people I love get failed twice over: by an app that kept insisting their bodies were doing something wrong, and by appointments where months of real, disruptive symptoms got waved off in eight minutes.
There's nothing wrong with an irregular cycle in these years. There's something wrong with the tools pretending otherwise. So we're making the opposite: something honest, quiet, and genuinely on your side — that helps you understand your own body and walk into that room ready.

No. Maren is a personal record — a way to track and organize your own symptoms and bring a clear history to your healthcare provider. It doesn't diagnose anything or replace a clinician. It helps you have a better conversation with one.
It stays yours. We will never sell it or share it with advertisers, you can export or delete it at any time, and we'll always tell you plainly what we store. See the three promises above.
Not yet — we're building it with founding members first, so the people who'll actually use it shape what it becomes. Reserve a spot and you'll be among the first in, at the founding price.
Yes, fully. Ask any time before launch and we return it, no questions. If you stay, it comes off your first year. We only charge the full price once Maren is ready and you've confirmed you want in.
That's a design goal, not an afterthought. Maren is built to be simple and readable, with logging that takes seconds. If it's not effortless, we've failed.
Join the early-access list. We'll only write when there's something real to share.
