Catch the hard moment

Tell Niyora how you feel. Get one small thing that fits, done in about a minute.

Understand why

Short, cited cards that explain what your body is doing, and that it passes.

It knows your week

Mark your last period once. Niyora learns when PMS is likely to land, and gets you ready.

What no one told you

Your hormones are normal. Your brain just feels the shift more.

The difference between a hard PMS week and an easy one isn't your hormone levels. It's how strongly your brain responds to the same normal rise and fall. Two in three women feel it as mood swings.

Same hormones, different response.

When researchers measured them, women who feel awful before their period had the same hormone levels as women who feel fine. The whole difference is sensitivity.

NIMH · Schmidt & Rubinow; Hantsoo & Payne, 2020

It's wired in, and it runs in families.

Premenstrual sensitivity is about 56 percent heritable. The same shift other people barely notice, your system actually feels. A bit like having sensitive skin.

Dubey et al, Molecular Psychiatry, 2017

It has an end date.

When researchers switched these hormones off, the symptoms cleared. When they switched them back on, they returned. It rolls in, and it rolls out, every cycle.

How Niyora helps

Notice it. Steady yourself. Understand why.

It sees your week coming

Ready before it hits.

You mark your period once. Niyora predicts the days when PMS tends to land, softens its whole tone for that week, and helps you get ahead of it. No tracking of you, no wearables.

Made for how you feel

Sixty seconds, when you need them.

Pick the feeling: irritable, anxious, low, foggy, overwhelmed. Niyora hands you one thing that fits. Cold water on your face. Legs up the wall. A slow breath with the orb.

The reframe that lands

Why, in plain words.

A short card tells you what's happening. Your alarm is turned up today. This passes. Not a mantra, the actual biology. You rate how you feel before and after, so you see the shift for yourself.

The people around you

PMS strains relationships. It doesn't have to break them.

The week before your period, your reserves run thin and small things land sharp. It isn't that you love anyone less. When you steady yourself first, there's less to spill onto the people you care about.

Name the week

One sentence gives them context.

"I'm a few days before my period, so I might be more sensitive this week." A sharp moment stops being a mystery.

Ask plainly

Don't make them guess.

"Can you handle dinner." "I need a quiet evening." A plain ask is easier to meet than a mood to read.

Repair fast

A message, already written.

If there's a blowup, Niyora hands you a short, honest apology, ready to send. One rough moment isn't the whole story.

Privacy, locally

Nothing leaves your iPhone. Ever.

Your cycle and your feelings are the most personal data there is. Most apps want an account and a server log of your worst days. Niyora wants none of it.

No accounts

Open the app. That is the entire onboarding.

No telemetry

The app makes zero outbound network requests of its own. Verifiable in source.

Local only

Your period dates and what you write live on your phone. Never read off device.

Why I built Niyora
Neha Prasad

I went looking for a way through PMS that didn't ask me to change my body.

I'm a doctor, so I started where I trust: the research. And the pattern was hard to miss. Most of what's offered for PMS either medicates it or just tracks it. Very little helps you in the actual hard hour.

Then I found the quieter, stronger thread. The most reliable, least invasive way through a hard PMS week is emotion regulation. Learning to name what you feel, settle your body, and see the thought from a step back. No hormones to take, no device to wear, no data to hand over.

That finding is the whole foundation of Niyora. Everything in the app is one small rep of emotion regulation, done in about a minute. I built it for myself first. Now it's yours.
