About this app

PureOne turns the health data you already have into clear, personalized guidance — so you always know how much energy you have, when to push, and when to rest.

YOUR AI HEALTH ASSISTANT
Available 24/7, PureOne AI connects the dots across your sleep, stress, and recovery and turns them into simple, personalized next steps.

BODY ENERGY
One score from 0 to 100 that charges while you sleep and drains as you move and stress through the day — see exactly what fills you up and what wears you down.

ADVANCED SLEEP
Wake up to a clear Sleep Score with stages, duration, and consistency, so you understand how well you actually rested.

RECOVERY & READINESS
A daily read on how prepared your body is to perform, built from your sleep, resting heart rate, and overnight HRV.

SMART STRAIN
See how hard your body is working, with a personal target range so you train at the right intensity without burning out.

STRESS RESILIENCE
See how stress shows up in your body in near real time, and find balance between moments of strain and recovery.

EFFORTLESS NUTRITION
Log meals in seconds with Barcode Scan, AI Meal Scan, or Search, and track calories and macros — what you eat versus what you burn.

SMARTER TRAINING
Your Training Load shows whether you're under-training, in the optimal zone, or overloading. Follow guided Strength and HIIT workouts.

BIOLOGICAL AGE
Discover how old your body really is, and watch how your habits move the number over time.

VITALS & TRENDS
Follow resting heart rate, HRV, respiratory rate, weight, SpO2, and sleep across daily, weekly, and monthly trends.
