One small practice at a time, chosen for the day you're actually having. Nurii learns what you do, what you skip, and quietly rebuilds tomorrow around it.
iPhone · free during beta · no wearable needed
You skipped this morning. Nothing nags. On Home that evening: Morning ritual missed. Tonight's is adjusted with this in mind.
Three skips in fourteen days and a practice leaves your plan altogether.
A notification, not a change. It says what it noticed and asks how you want to handle it.
When it asks, how much it asks for, or the practices themselves. Every answer changes what Nurii does tonight - nothing is a survey.
A weekly read on what's forming, what left you calmer, and what it's easing off - in plain words, with no streak to break.
Setup asks four things, all optional. None of it is a diagnosis and none of it is said back to you - it just shifts what Nurii suggests, and when.
Perimenopause, postpartum and menopause each change sleep, energy and what's worth asking of yourself. Nurii follows the phase you're in and moves the work to where it lands.
Your wind-down and your wake-up are set to your day, not a default one. A night owl isn't asked to be up at six, and an early bird isn't kept up for a late ritual.
Neurodivergent brains regulate dopamine, focus and overwhelm differently. That changes which pillars Nurii leads with, how long a practice runs, and when it asks.
Tell it what you already do and it builds around that rather than on top of it. Setup ends on a real sequence for tonight, from your three priority pillars.
Everything here can be edited later in Profile.
A wind-down opens by asking how you're arriving, and adapts to the answer. Every step says why it's there. The light only ever comes down - once you're settling, nothing in Nurii brightens back up.
Three practices, nine minutes. It asks how you're arriving before anything starts.
Six of the twelve screens in the wind-down arc.
Oestrogen moves across a month; testosterone across a day. Nurii follows whichever clock is yours - what it asks for, when it asks, even what's on the plate - and puts the work where it will actually land.
It tracks this itself, so it works whether or not you use Apple Health.
Eight everyday habits that shape how your brain feels and functions. You never have to think about which one you're working on - Nurii picks.
Settle your nervous system in minutes, matched to your day.
Learn to recognise the load before it stacks up.
The brain's clean-up cycle. Everything else is built on it.
Small deliberate shifts, repeated, build new pathways.
Your most direct lever, explained without the supplement noise.
Three honest minutes, and what it does over months.
The most consistent predictor in the whole literature.
Resistance, somatic and yoga, matched to what today allows.
Your brain keeps rewiring at every age. The research on what shifts that is unusually consistent - it points at sleep, movement, food, stress and connection. Nurii turns it into something you can actually do on a Tuesday.

These are findings about the practices, not promises about Nurii. Nurii is not a medical device, and it doesn't diagnose, treat, cure or prevent any condition.

"My dad died suddenly when I was 26. What I wasn't ready for was what it did to my body."
The grief I half expected. The rest I didn't. Panic attacks, anxiety that turned up without a reason, skin and hormones that stopped behaving. My nervous system had decided the danger was still happening and stayed there, and nobody had told me grief could do that.
It took years to come back. What worked in the end wasn't a supplement or a test result - it was breathwork, movement, sleep, and the slow, unglamorous work of doing small things often enough that my body believed me.
Now I watch my nan live with dementia, and I think about brain health differently. Not something to fix later. Something you look after now, in small daily ways.
That's why I built Nurii.
Thirteen testers ran Nurii for four weeks each through summer 2026, with interviews at the start and the end. Everything on this page survived that.

Therapists, longevity clinicians, nutritionists, breathwork and somatic coaches, EFT practitioners, trainers. If you work in this every day and want to shape what people practise, we'd like to talk. Everyone who joins is identity-verified before they appear.
Fourteen days of full access, coach and personalisation included, then one Premium plan: £59.99 a year, or £9.99 a month. No cut-down free tier, no tiers to compare. Free for everyone in the beta.
No. Nurii works from day one on your calendar, your phone and what you tell it. Connect Apple Health and it also reads your HRV, resting heart rate, sleep stages, mindful minutes, steps, workouts and cycle starts - and writes your sleep window and completed practices back.
No. Nurii supports everyday habits and self-regulation. It is not a medical device, it doesn't diagnose or treat anything, and it isn't a substitute for professional care. The coach is honest about its limits, and points you toward real human support rather than trying to handle a crisis itself.
Two things: your daily nudge, and the coach you can talk to. It runs on Claude, made by Anthropic, called from our own servers so no keys sit on your phone. It uses the pillars and goals you chose, your cycle phase if you track it, your practice history, and how you responded to past suggestions.
Your data personalises your experience inside Nurii. It isn't sold, and your conversations are not used to train AI models. You can review or remove your information at any time.
Always. Nurii suggests, you decide. Skip, swap or ignore anything. Over time it learns what you find useful and quietly drops what you don't.
Nurii is in open beta on iPhone. Free while we're testing, and you keep everything you build.
