Wearable Devices - FAQs

The most frequently asked questions for wearable devices.

Is there a specific wearable device recommended to use with Labfront?

We recommend Garmin devices for the best balance of cost and performance.  For the most affordable and compact device, we suggest using the Garmin vívosmart 4.   If you’d like a bigger display, longer battery life and more sensors, then we recommend using the Garmin Venu® Sq. 


Is Labfront compatible with non-Garmin devices?

Yes, Labfront is compatible with a wide range of devices, the latest list of compatible devices is available on our website.  We do update this list from time to time, so if you are interested in a specific device that is not listed on the website, then please reach out to partnerships@labfront.com


How do I enter Bluetooth pairing mode on my Garmin device? 

For Garmin Venu® Sq, to enter Bluetooth pairing mode select Settings -> Phone -> Pair with phone.  For more tips and advice about pairing your Garmin Venu® Sq, please visit


For Garmin vívosmart 4, to enter Bluetooth pairing mode press device key (ie; below the screen)  to access the menu ->

Swipe the screen and select Phone Bluetooth -> Select rotating arrows.  For more tips and advice about pairing your Garmin vívosmart 4, please visit https://support.garmin.com.


How long will it take to charge my Garmin wearable device?

Charging a fully depleted battery takes about 60 to 90 minutes. For more tips and advice about charging your Garmin wearable please visit https://support.garmin.com/.


How often do I need to charge my Garmin wearable device?

The battery life of your device will depend on a number of factors including the setup of your research project and how often you interact with your device.  It can be anything from a couple of days up to a week.  For most projects, we recommend charging your device at least every other day.  


How accurate is my Garmin device for measuring heart rate, Sp02 or other physiological data? 

Garmin devices have been used successfully for physiological data collection across many different types of research projects, including clinical trials. As with any wearable sensor, the quality of data collection depends on the amount of extra signal noise. Device fit, device usage, and motion intensity all affect the resulting accuracy. For a list of best practices, see related question: What are some best practices to help optimize for accuracy from wearables?


What are some best practices to help optimize for accuracy from wearables?

Many factors may affect the accuracy of your wearable device for measuring physiological data, including the device fit and level of activity/motion. For this reason, we recommend the following tips: 

  1. Fit matters: Make sure all participants know how to correctly wear said wearable device.
  2. More samples, more insights: Collect extra samples and average them to get more accurate representations.
  3. Less movement, higher accuracy: Try to take measurements during low activity periods when possible, such as when one is sitting at a desk or sleeping.


What does Garmin’s Stress Level measure?

Stress Level is found on some Garmin wearables allowing a user to determine their current level of stress based on their Heart-Rate Variability.  For more information about how Garmin measures Stress Level, please visit https://support.garmin.com


Can Labfront detect faulty wearable devices?   

The best way to detect faulty devices is to observe data collection from the Labfront Dashboard.  If you observe on the Dashboard that device data is not being collected for an extended period of time, then the device may be faulty.  In this situation, we recommend swapping or replacing that device to observe if the issue still occurs.
