Your menstrual cycle affects your energy, focus, and capacity. But nothing in your calendar, workplace, or daily routine helps you see it, let alone plan around it. Nadi changes that.

Privacy

Your cycle. Your data.

We built Nadi for ourselves. We use it every day, which means our own cycle data lives here too. We don’t want our data used by other people, and we won’t do that to yours.

Your data is encrypted and stored on servers in the EU. Everything we do follows GDPR, we’re registered with the UK’s data protection regulator and have completed a full privacy assessment.

We will never sell your data. Not to advertisers, not to insurers, not to anyone.

Because Nadi works with your existing calendar, it’s totally up to you what you use in your calendar. Rename your phases to anything you like. “Luteal” can become “Focus week”, “Recharge”, or something only you understand.

Delete everything, permanently, whenever you want.

Questions? Ask us anything at hello@nadi.health. We’d rather you ask than wonder.

We believe your cycle is a rhythm that you should pay attention to. Just like your 24-hour circadian rhythm, your menstrual cycle journey affects your energy, capacity and focus.

Four phases, four strengths

What you feel → what's happening .

Tap a phase to see what's going on under the surface and how to work with it.

Menstrual phase Day 1–5

You might feel

quiet, reflective, slower

What's happening

Hormones at their lowest. Your body is shedding and resetting.

Plan more

rest, journaling, gentle movement

Follicular phase Day 6–8

You might feel

rising energy, curious, bright

What's happening

Oestrogen climbs. New ideas land easier; stamina returns.

Plan more

brainstorms, new projects, learning

Ovulatory phase Day 9–14

You might feel

peak confidence, sharp, social

What's happening

Oestrogen peaks with a testosterone bump. You feel most 'on'.

Plan more

pitches, presentations, big conversations

Luteal phase Day 15–28

You might feel

focused, detailed, then slowing

What's happening

Progesterone rises then falls. Attention narrows; energy tapers.

Plan more

deep work, editing, wrapping up

Megan, founder of Nadi

“Up until my late 20s I never knew I had another cyclical pattern outside of a 24 hour one. But I’d had enough of crippling pain every month and not understanding why, I decided to get to the root cause which led me down a deep cyclical re-education.

I tracked my full cycle, every day, in detail, on an excel spreadsheet, for over a year. That’s when I realised I wasn’t inconsistent; my symptoms, energy and focus all followed a pretty predictable pattern.

Nadi is my way of helping other women understand their own unique rhythm, so they can live, work and plan in a way that recognises it.

Women are not ‘inconsistent’, or ‘unpredictable’, we are cyclical. And we are living in a world that doesn’t understand this. I would love to change that.”
