## What is Azume?

Azume is the app for the Azume One, a screenless sensor that attaches to the back of your watch and measures continuously, day and night. It tracks heart rate and resting heart rate, HRV, blood oxygen and stress around the clock, sleep with its full stage breakdown, plus steps, distance, calories and workouts, whether you log them yourself or Azume One detects them, including GPS routes for workouts that cover ground. Each morning the app turns all of that into three scores: Recovery, Sleep and Wellness.

Open the app in the morning to know whether today is a day to push or a day to hold back. Open it in the evening and check how your day actually went.


THREE SCORES EVERY MORNING

RECOVERY SCORE
Built from your overnight HRV, resting heart rate and sleep. Are you ready
for a hard day, or should today be lighter?

SLEEP SCORE
How the night actually went, not just how long you were in bed.

WELLNESS SCORE
Recovery, sleep and stress in one number, so you can see the week taking
shape.


METRICS VISIBLE IN AZUME APP

SLEEP
- Deep, light and REM sleep, plus time awake
- Your full night laid out hour by hour
- Bedtime and wake time, detected automatically
- Nightly score and long-term trends

HEART

- Respiratory rate, measured on demand
- VO2 max estimate, tracked over time

STRESS
- Continuous stress reading derived from your heart signals
- Banded low, moderate and high across your day
- See when the day got demanding and when it didn't

ACTIVITY
- Steps and distance, broken down across the day

  separately and together

- Daily step and calorie goals, with a nudge when you reach them
- Streaks to keep you going

TRENDS

- Any single reading always sits in the context of everything before it


WORKS WITH APPLE HEALTH
Turn it on and your measurements appear in the Health app alongside
everything else you track. One-way and reversible. Azume writes, never
reads, and switching it off removes Azume's data from Apple Health again.


PRIVATE BY DESIGN
Your health data is the most personal data you have.
- No advertising SDKs, no analytics trackers, nothing sold
- Stored in the EU under GDPR
- Delete your account and all of it from inside the app, no email, no wait


REQUIREMENTS 
Azume requires an Azume One, which attaches to the back of your watch or can be worn on its own with the FitBand. Syncs over Bluetooth.

Azume is not a medical device. It is intended for general wellness and fitness purposes only.
