Every body's map is different.
nrsh is your compass

Everyone’s body responds
differently.

The same meal that sits well for one person leaves another bloated, foggy, and second-guessing every plate. Generic advice, weeks of elimination, and food logs full of guesses can’t see what’s actually happening inside you.

Who it's for

Two ways in.
One personal map.

Whether something has been bothering you or you just want to understand your gut better, nrsh meets you where you are.

Settle a gut issue

If food leaves you bloated, uncomfortable, or second-guessing every plate, nrsh helps you find what works for you and settle your gut, without weeks of elimination.

Understand your gut

If you just want to know how food affects you, nrsh builds a picture of what makes you feel your best, so you can eat with confidence and keep up as your body changes.

Your gut is always changing

Life moves. So does your gut.

The foods that sit well can shift with a new routine, a new goal, or a new chapter. nrsh keeps up, so your map is never out of date.

On a new medication

Your gut can change week to week. See how, in real time.

Changing your diet

Going plant-based, higher-protein, or trying something new? Watch your gut adapt.

A new chapter

Pregnancy, a new decade, life after illness. Your gut shifts; nrsh keeps pace.

Training and performance

Dial in what fuels you and sits well, on training days and race day.

What nrsh is

A map that’s
only yours.

As you eat the way you normally do, it reads how your body responds in real time and quietly builds a personal picture of which foods work for you and which ones don’t. The longer you wear it, the sharper it gets.

Personal. Real time. Actionable.

Small, light, and made to disappear into your day. It works quietly in the background.

02
Step 02 · Build your map

Log your meals and check-ins

A few seconds is all it takes. With every meal and check-in you log, nrsh sharpens its picture of how your body responds.

03
Step 03 · Your compass learns

Clear answers, in plain English.

A signal per meal. Clear, Caution, or Pause. Over time, nrsh learns how your body responds to different meals, building its map to give you real-time, actionable insights and recommendations, to avoid reactions that stop you from doing the things you love, so you can get on with life.

Your signal

Where you are,
at a glance.

Why nrsh is different

Personalised, real-time, actionable. meeting you where you are.

vs elimination diets

Weeks of restriction that tell you what, but never why.

nrsh reads how your body responds to different meals, so the answers come from your actual life and not a checklist.

vs food logging apps

They log what you ate. nrsh shows how your body responded.

A diary records the meal and how you felt. nrsh learns the pattern of how your body response to different meals to help guide you avoiding reactions, not just manage symptoms.

vs breath testing

A clinical snapshot on a single day in a single room.

nrsh is continuous, wearable, and yours. Your map keeps updating as you live your life, giving guidance on meal choices in real time.

For practitioners.

If you work with patients with food intolerences, nrsh gives them a clearer picture to bring into the room. Their own data, collected day by day between sessions, in plain language you can both read together.

Good ones to ask

The questions we
hear most.

A few things we get asked. If yours isn’t here, write to us.
What does nrsh actually read?+
nrsh reads how your body responds to food in real time, through a small sensor worn against the skin. The output is plain English. A Clear, Caution, or Pause signal per meal, personal to you. Over a few weeks those signals build a map of which foods sit well, which ones don’t, and how that changes over time.
Is this for food allergies?+
No. nrsh is built for food intolerance, not allergies. Intolerances cause real discomfort, but they don’t involve your immune system. If you suspect a true allergy, that needs a clinician, not a wearable.
How is this different from a CGM?+
A CGM tracks blood glucose. That tells you part of the story, mostly about sugar and carbs. nrsh reads a different response from your gut, tuned to food intolerance and digestive sensitivity.
How long until nrsh learns how my body responds?+
Signals start showing up from your very first meal. A real personal map, the kind that points to specific patterns and swaps, usually takes two to three weeks of normal eating and logging.
Why might the same food get a different signal on different days?+
Your gut isn’t a fixed system. Sleep, stress, what you ate earlier, where you are in your cycle, recent illness. They all shift the picture. nrsh accounts for the cumulative load across the day, not just the meal in front of you, so it stays honest about what’s actually happening.
Is nrsh medical advice?+
No. nrsh is a knowledgeable friend, not a diagnostic tool. It gives you a personal picture you can use yourself or take to a clinician. Many of our users share their map with their health professionals between visits.
When and where will it be available?+
Australia first, then the USA. Early access opens in 2027. The waitlist is open globally, and we’ll keep you in the loop as your region comes online.
What will it cost?+
Final pricing will be shared closer to launch. It’ll be asubscription with the device included, so there’s no upfront hardware cost to figure out if it’s right for you.
