Vital Signs Monitor — Companion App for Bluetooth Health Devices
⚠️ EXTERNAL HARDWARE REQUIRED
This app is a companion display and notification tool. It does NOT
take measurements on its own. You MUST own one or more compatible
Bluetooth medical devices (thermometer, pulse oximeter, and/or blood
pressure monitor) for this app to function. Without these external
devices, the app cannot display any vital signs.
WHAT THIS APP DOES
Vital Signs Monitor pairs with your existing Bluetooth-enabled medical
devices to display the readings those devices produce, store a local
history of those readings, and notify family members when readings
from those devices fall outside ranges you configure. The app itself
does not measure temperature, pulse, oxygen saturation, or blood
pressure — all measurements come from your external certified medical
devices.
REQUIRED HARDWARE (NOT INCLUDED, SOLD SEPARATELY)
You must already own at least one of the following Bluetooth devices:
- A compatible Bluetooth thermometer (for temperature display)
- A compatible Bluetooth pulse oximeter (for SpO₂, pulse rate,
respiration rate, perfusion index display)
- A compatible Bluetooth blood pressure monitor (for systolic,
diastolic, and pulse display)
The app supports any combination — one, two, or all three — based on
which devices you own.

IMPORTANT DISCLAIMER
This app is a display and notification companion for third-party
Bluetooth medical devices. It does not measure, diagnose, treat, or
provide medical advice. Measurement accuracy is the responsibility of
the certified Bluetooth devices you connect to it, not this app.
This app is not a medical device, is not a substitute for professional
medical care, and should not be used to make clinical decisions.
Always consult a qualified healthcare professional for medical advice.
HARDWARE COMPATIBILITY
To use this app you must already own one or more compatible Bluetooth
medical devices, sold separately. The app will not produce any
readings without these external devices connected.
