Health, the whole picture
A real physiotherapist & nutritionist behind it
Hi Krissy is built on the clinical approach of Kristen Witt — a qualified 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
Evidence-based changes that start exactly where you are and build 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.
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.
A trusted network of practitioners, hand-picked by Krissy
Your health journey doesn't stop at the app. When you need one-on-one support, tap into a curated network of practitioners Krissy has personally chosen — so the care you get in person matches the care you get in Hi Krissy.
Complete members save 20% on every consultation
On the Complete plan, you get 20% off consultations with any practitioner in the Hi Krissy network — an easy way to make expert, in-person care part of your routine.
On Core or Plus? You're welcome in the network too — you simply pay the standard consultation rate.
Hand-picked by Krissy
Every practitioner in the network is personally chosen by Krissy — physios, dietitians, and allied-health experts she knows and trusts to care for you the way she would.
Qualified and vetted
No directories, no guesswork. Just genuine professionals who share Krissy's approach to nutrition, movement, and long-term wellbeing.
Care beyond the app

Cooking for other people?
Add up to four people in your household to your circle — free. They get the shared shopping list and what’s for dinner, and they keep their own allergies up to date so meals are safe for everyone.

- Children never get targets. We hold a first name, a rough age and any allergies — so we can cook safely for them. Nothing else, ever.
