Finally, a map for The Zone of Chaos
Meet PeriPro: an app for perimenopause built by a woman in perimenopause. Cycle-aware reminders, supplement and HRT schedules, pattern detection. Finally, an app that actually helps you with this stage.
Most of the popular cycle tracking apps were built by men.
Which explains a lot.
The people who built most of those apps have never experienced The Coming of Rage.
Everything that matters
in one cycle-aware app.
Real flows from a real app — not concept art.
Reminders that fire based on where you actually are in your cycle — not the calendar.
Cycle Day, phase, and the next-period prediction — without the period-tracker baggage.
Your whole picture in one place — insights, symptoms, supplements, hormones, and a personal reference library.
Severity logging that takes five seconds and saves automatically.
Built by someone who needed it.
When I hit perimenopause, everything got infinitely harder and everyone - including me - treated me like I was crazy for saying I was perimenopausal at 40. As my cycle becomes more erradic and my hormones take random turns on amusement park rides at unpredictable times, trying to adjust or even guess what might be coming has been rage-inducing and crazy-making in a way no one prepared me for. I’ve used half a dozen cycle tracking apps over the years, and I’ve been perpetually frustrated that none of them could even remind me to take certain supplements or hormone therapies ONLY during a specific phase of my cycle. The app knows what phase I’ll be in on a random Tuesday two months from now. It just can’t do anything with that. I’ve spent years now trying to manually keep track of supplements, biohacking experiments, research on myself and my own complicating factors, and the tracking alone has been exhausting. I keep trying to make existing apps work for my specific needs, but they always fall short.
So I built PeriPro. Now, I can set up a supplement, pick a time of day, a phase of my cycle, and the app manages the daily checklist and reminders for me. I can pull in my Oura data and see how my sleep actually shifted when I started taking magnesium at bedtime. And the cycle-aware and time-of-day notifications help me remember to take everything at the right time in the right combinations to feel better. I can upload my lab results and the protocol my doctor put me on and have the app keep track of the context behind each supplement or hormone treatment. I can even set up and track that viral Pepcid + Allegra experiment everyone’s talking about on social media and see in my data whether it actually changes my symptoms. I can put my whole regimen in my Apple or Google Calendar if I want to.
Since I’ve been using it, my luteal phase has gone from anxious, sleep-deprived emotional chaos to calm and productive like I’m ovulating. And I have so much brain power back just from not having to burn mental energy manually keeping track of everything. The app knows I already have enough to do, so it does that part for me.
I’m tired of products for women that were built by people who can’t personally relate to what the product is for.
It’s time more of us built the things we need. That’s what the waitlist is for. I built PeriPro for me, but I know so many other women who need the same help I did. The app is built and the screenshots you see here are real app screenshots I captured with my phone in my hand, not prototyped marketing fluff or AI-generated hype. I'm using it every day and it's making a difference for me, but getting it ready for public use at scale is a different thing. Signing up for the waitlist will help me understand the best approach for bringing the app from my private usage to everyone in the Perimenopause Posse. We could all use a little help.
