The last thing you want during an attack is filling in a log

The gap between what apps ask you to do and what you can actually do during an attack is the whole problem. Penumbra exists because that gap shouldn’t.

You can’t log during an attack

Your eyes are closed. Your head is splitting. The last thing you can do is tap a screen.

You have to reconstruct data from memory

You walk into your neurologist’s office with fragments. Dates blur. Triggers vanish. Nothing changes.

There is a pattern you can’t see

Your worst attacks happen on the same days every month. You know it, just can’t prove it.

You’re allowed to understand your condition – with a solid migraine diary app

Understanding your own condition is a right, not a feature. Penumbra is the migraine tracker built for the inside of an attack and the appointment that follows it.

I’ve been tracking my cycle and migraines separately for six years. Seeing them on the same timeline took two weeks to confirm what I’ve suspected the whole time.

Sarah, Portland

Chronic migraine sufferer

“

I sent my neurologist the PDF before my appointment. She said it was the most complete data she’d ever seen from a patient. We changed my treatment plan in that one visit.

Maya, Austin

Newly diagnosed

“

I needed Botox approval and I had nothing to show for it — just a vague sense that my attacks were getting worse. Six weeks with Penumbra and I walked in with a PDF, a MIDAS score, and a documented frequency that my neurologist could actually act on. We changed my protocol in that appointment. I’d been waiting two years for that conversation.

Rachel, New York

CGRP preventive user

“

My neurologist told me to keep a headache diary before my first appointment and I genuinely didn’t know where to start. I tried Notes, I tried a spreadsheet, I gave up twice. Then I found Penumbra and just… spoke three words when an attack started. By the time my appointment came around I had six weeks of structured data I didn’t even know I was building.

Mia, Austin

Episodic migraine sufferer

“

I’ve tried over 10 apps. I always quit around the three-week mark because logging during an attack is just not possible with those interfaces. Penumbra is the first app that seems to understand that the worst moment to open an app is exactly when you need to log. I’m at four months now. That’s never happened before.
