About Niyora

Niyora is an app for the days before your period, when your feelings get louder than usual. It is built by one person, in Norway, and it is early.

Who is behind it

I'm Neha Prasad. I'm a doctor who wanted to work on women's health. I learned design, spent years in health tech as a designer, and now I get to build the thing I actually wanted to build.

Why it exists

I used to cry a lot before my period.

It got predictable. If I felt low, or didn't want to leave the house, or got into a fight with my husband, or felt small at work, I could pretty much guess my period was coming. I was reading my own body right. I just had nothing to do about it.

I saw doctors in three countries. All of them said it's normal and there's not much you can do. People told me to try period apps, so I did. Every one of them asked me to log how I felt. Anxious. Irritable. Moody. I already knew that. I was the one going through it. What I wanted was the next sentence, and nobody had one.

So I went and figured it out myself.

What I found

It isn't the hormone drop before your period. Women who feel awful have the same hormone levels as women who feel fine. What's different is how strongly your brain reacts to that drop. That's personal, so there's no one fix. Part of it is lifestyle. The rest is learning to handle emotions one at a time.

Then I looked at what actually happens in the moment. When you feel low, your brain is busy protecting you. It won't rephrase things for you. It won't hand you a kinder read. So you react instead of respond. Then you deal with what you said, and you regret it.

That was me, every month, and no app was touching it. So Niyora predicts your week like the others, and then does the part nobody else does: it helps you reflect, regulate, and respond in the actual hard hour. Every piece of it is one small rep of emotion regulation, done in about a minute.

How I checked it

I pulled around three thousand papers from Europe PMC and used AI to read through them and rewrite what they said in plain English. The 26 studies Niyora is built on are published and graded strong, moderate, or weak, including the weak ones.

Then I checked the whole field across 31 questions and published that too. There are 168 papers on the genetics of premenstrual symptoms and zero real trials. There is thirteen times more research on cycles in animals than on premenstrual self-harm. Nobody had put those numbers in one place before.

Before a fact goes in the app, I have AI agents argue against it. If it can't hold up, it doesn't ship. Four claims lost their argument and got cut. One of them would have made great copy. Cutting it was right and I didn't enjoy it.

What I gave up

I wanted the AI to run entirely on your phone, so nothing ever left the device. I got it working. It reflected well enough and it gave bad suggestions, and the suggestions are the half that has to work. A reflection you can't act on is just a nice sentence. So I dropped it and kept the privacy promise another way.

I also wanted real evidence instead of self-report, by reading heart rate variability to find an actual pattern across the cycle. It doesn't work. Phones only pick up clean readings when you're still, which is almost never during the moments that matter.

Both would have been beautiful. Neither would have been good for you. Letting them go was most of the work.

What it will not do

• No ads, no profile, no data sold.
• No account needed. Your period dates stay on your device.
• Before your words go to Moon's AI, names and identifying details are stripped on your phone. What is left can't point back to you.
• It is not a diagnosis, a therapist, or crisis care. If you're in danger, contact your local emergency number.

Because nobody here can read your writing, nobody here can catch a mistake either. So the crisis check is built to be jumpy on purpose. A plain keyword check runs first, and the AI can never turn it off, only on. If it's unsure, it escalates. The long version lives in the privacy page.

Where it is now

Niyora is in testing, not on the App Store yet, and there's no revenue. That's the order I picked on purpose: the safety and privacy work a mental health app has to finish comes before it takes anyone's money. I know what it costs to run and I know who it's for. I don't yet know the right way to charge for it, and I'd rather say that than invent a number.

What's new tracks what ships. Say hello if you want to shape it.
