The Fiit Tracker 2.0 is no longer available for sale from Fiit, but users who did purchase can troubleshooting their tracker with some common issues below :

I’m charging my Sensor, but no light is coming on

Possible causes:

  1. The connector supplied is an adapter only and must be inserted to a USB-C cable attached to a wall plug or laptop, if you find this is not charging :

  2. Is the cable pushed all the way in ok?

  3. Don't use the connector provided - use a USB-C cable straight into the device

  4. Try an alternative USB-C cable

  5. Try charging via a laptop. If this is not possible, try an alternative wall plug.

  6. Link to the Prevayl App via the instructions in the link above - does it link ok and show your battery life?


    If you have tried all 6 of these options this and the Sensor is still not charging please contact [email protected] to log your issue and for further help.

I’m trying to start a class by my Sensor won’t connect to the FIIT app

Possible causes:

  1. Plug in the Sensor via the provided charging cable, ideally into a computer. If a red or green light appears, the Sensor is functioning correctly; if no
    light appears after 10 minutes, please email [email protected]

  2. Do you have Bluetooth permissions activated for the Fiit App?

      1. Go to your phones 'Settings' app

      2. Scroll your app to find Fiit

      3. Toggle on Bluetooth for Fiit

My battery life is not lasting long

Ensure you have the latest firmware version on the sensor?
Open the Prevayl App and link your device :

  1. Tap the Sensor on screen in the app to open the settings

  2. If you see Firmware Update - Tap to update to the latest version

  3. If no firmware update is showing as available then your firmware is up to date.

    If your sensor is running the latest firmware, take a look at Prevayl's advice

I’ve started a class but I don’t think the HR is correct / my Heart Rate is jumping

Possible Causes :

  1. Are you connected to the right sensor?
    On the back of the Prevayl Sensor is a 4-digit number,
    ensure that the device that the app is showing as connected to
    matches the code on the back of the Sensor. (this code is also on the
    underside of the sliding part of the Sensor box)

  2. Ensure the Sensor is inserted horizontally into the pocket
    of the chest strap with the rubber shims facing towards the body.
    When wearing the chest strap, ensure that the
    pocket is facing up and that it’s central to allow it to pick up
    the most accurate data.

  3. Really dampen the electrodes on the inside of the chest strap.
    The sensors need moisture to improve the accuracy. If the sensor jumps from high to low at the start of the class, add more water to the pads whilst wearing it, it's quick and easy and will improve the connectivity dramatically.
