What the app actually does
Nutrition tailored to you
Personalised meal plans based on your preferences, restrictions, and goals. No more guessing what to eat.
Movement programs that fit your life
Whether you have 15 minutes or an hour, get exercises designed for your fitness level and available equipment.
Virtual Krissy learns as you go
It learns from what you rate, log and skip, and reshapes next week around it.
Built for busy schedules
Quick meals, flexible workouts, and async support. Everything designed to respect your time.
Hi, I'm Krissy
I've spent my career treating patients as a physiotherapist, and I kept seeing the same thing: people don't come unstuck because they don't know what to eat. They come unstuck because dinner has to work for four people on a Tuesday.
So I built Hi Krissy to work the way I actually work in the clinic — around the week you've got, the people you're feeding and the body you turned up with today.

What actually happens, in four steps
Answer a few questions
What you're working towards, what you can't eat, what equipment you've got, and how much time you actually have.
Your week appears
A week of meals everyone in your house can eat, and sessions that fit the days you've actually got.
Shop and cook from it
A shopping list sorted by supermarket aisle, which already knows what's in your pantry.
It adapts as you go
Every check-in reshapes the week ahead — a shorter session after a bad night's sleep, different meals when something doesn't land.

Health, the whole picture
A real physiotherapist & nutritionist behind it
Hi Krissy is built on the clinical approach of Kristen Witt — a registered physiotherapist and nutritionist — not generic internet advice.
The whole picture
Movement, nutrition, sleep and mental wellbeing are treated together — because looking after one part of your health alone only ever tells half the story.
Small, lasting steps
Changes grounded in the Australian Dietary Guidelines and physiotherapy practice — starting where you are and building gradually, because overhauling everything at once is the thing that doesn't last.
Personalised to you
Your plan adapts to your goals, your body and how busy your week actually is — no two people get the same experience.
Virtual Krissy is AI, built on Kristen’s clinical approach. It gives general guidance, not personal clinical advice — anything clinical goes to a qualified practitioner.
Looking for an In-Person Consultation?
If you're based in Sydney, visit Hi Movement — Krissy's physiotherapy and nutrition clinic located in Leichhardt. Get hands-on treatment, clinical pilates, and personalised care face-to-face.
From injury rehabilitation to nutrition consultations, the Hi Movement clinic offers the full range of Krissy's services in person.
When you want to be seen in person
Some things need someone in the room. Book a consultation with Kristen at Hi Movement in Leichhardt — physiotherapy, clinical Pilates and nutrition consultations, face to face.
Complete members save 20% on consultations
On the Complete plan, consultations with Kristen are 20% off.
Applied by Kristen when you book, on consultations at Hi Movement, while your Complete plan is active. Booking is through Hi Movement and paid there. On Core or Plus you're just as welcome — you pay the standard consultation rate.
The same person behind the app
In-person care is with Kristen herself — so what you're told in the room and what the app does the next morning are the same approach, not two different ones.
Hands-on where the app can't be
Physiotherapy, clinical Pilates and nutrition consultations — the things that need someone in the room with you.
Never required
The app stands on its own, and booking a consultation is always your call. Nothing in Hi Krissy is gated behind seeing someone in person.
