About this app

Hi Krissy is a personalised nutrition and movement app for people with full lives and not much spare time.

Created by Kristen Witt, a qualified physiotherapist and nutritionist, it builds a week of meals and training around your goals, your kitchen and the time you actually have - then adjusts as your week changes.

NOURISH
• A weekly meal plan tailored to your goals, tastes and dietary needs
• Log a meal in a tap, or swap one you don't fancy for something that fits the same targets
• Allergies, intolerances and foods you avoid are respected throughout
• A shopping list built from your plan and sorted by aisle

MOVE
• A training programme that starts where you are and steps up gradually
• Guided sessions with clear form notes, plus easier and harder options mid-set
• Already train elsewhere? Add your regular sessions and we'll schedule around them
• Rest days are part of the plan, not a gap in it

YOUR DAILY BALANCE
Each day you get one number - your Balance - made of three parts: Nourish, Move and Recover. It is a glance, not a grade, and it shows you where your week is heading while there is still time to change it.

CHECK-INS THAT TAKE 30 SECONDS
A short morning check-in on sleep and energy, and an evening one on how the day went. Answer what you like and skip the rest. If you're run down, today's session eases off automatically.

PROGRESS YOU CAN SEE
Weight, measurements, sessions, intake and check-in trends over time — drawn from what you actually logged, never smoothed to look better than it was.

VIRTUAL KRISSY
An AI coach built on Kristen's approach to food and movement. Ask about today's session, a niggle, or whether you're getting enough protein, and it answers using your own logged data. It is not a practitioner and does not diagnose.

BACKED BY QUALIFIED PRACTITIONERS
• Rehab: a guided triage for niggles, with clear signposting when something needs seeing in person
• Tests and bloods: ask a qualified Hi Krissy practitioner whether a test is worth doing; results are recorded and explained, never diagnosed
• Men's and women's health: age-appropriate screening prompts and preventive information

ALSO INCLUDED
• Circles — share a shopping list with your household
• An accountability partner, if you want someone alongside you
• Health Connect for steps, heart rate and sleep
• Supplements, with interaction cautions and a prompt to check with your GP

IMPORTANT
Hi Krissy is a health and wellness app and it provides general guidance and coaching. It is not a medical device, does not diagnose or treat any condition, and is not a substitute for advice from your doctor or another qualified health professional. Always speak to your GP about symptoms that concern you, and seek urgent care in an emergency.
