About
QStat Companion connects your QStat to your iPhone or iPad over Bluetooth. View readings, manage connected sensors, and personalize your QStat from one app. A QStat is required: the app does not take measurements by itself.
READINGS AT A GLANCE
View heart rate and skin temperature from your QStat, with recent trends and last-updated indicators. Heart-rate readings follow your QStat's skin-contact detection.
CONNECTED SENSORS
Add supported accessories through your QStat for additional readings:
• iP900 finger pulse-ox: blood oxygen and respiration rate
• BP3 blood-pressure cuff: blood pressure
These readings require the corresponding accessory; they are not measured by the phone or supplied by the QStat alone.
MAKE IT YOURS

• Select a Companion font
• Choose 12- or 24-hour time and sync that setting to your QStat

MANAGE YOUR QSTAT

OPTIONAL APPLE HEALTH SYNC
With your permission, send supported readings to Apple Health through HealthKit. You can turn sync off in Companion to stop future writes and manage permissions in Apple Health. Health sync requires a compatible device with Apple Health available.
GETTING STARTED
You'll need a QStat and Bluetooth. Additional accessories are required for the connected-sensor readings listed above.

Readings are for your information only and aren't a substitute for professional medical advice. If you feel unwell or a reading worries you, talk to your care team or a health professional.
