Got your sensor charged? Great — let's get it connected to your phone. Pairing only takes a minute and you'll only ever need to do it once.
📡 Pairing Your Sensor
Wake up your sensor — give it a tap or a shake. Within a few seconds it'll start broadcasting and appear in the app
Open the Phreno app on your iPhone or iPad
Go to Settings → Bluetooth within the app
Select your device from the Nearby Devices list
Tap Connect — after a brief moment, you're paired!
Once paired, you're all set. From now on, your sensor will connect automatically every time you open the app, as long as it's nearby and charged.
✅ How to Know It's Connected
Look for the status indicator in the top-right corner of the app — it'll show Connected in green when your sensor is successfully linked. You can also head to the Bluetooth settings page in the app to see your sensor's current firmware version.
🔧 Having Trouble Connecting?
Don't worry — here are a few things to try:
Check the battery — make sure your sensor is charged and close to your phone
Toggle Bluetooth — turn it off and back on in your iPhone's settings
Plug the sensor in briefly — even just for a moment, this can help reset the connection
Shake the sensor — after a period of inactivity, the sensor enters sleep mode to save battery. A little shake will wake it right back up
Restart the Phreno app — close it fully and reopen it
If you see a firmware update prompt after connecting, just follow the on-screen instructions to get the latest version installed.
