The Fever Scout app will send alerts and record temperature even when your phone is in sleep mode or located in another room. Now you can have peace of mind knowing that Fever Scout will continuously track temperature on it’s own.



Keep a record of fever causes, temperature trends, and effective anti-fever treatments. Share the information with your physician or loved one.


Where is the correct placement for the patch?

For the most accurate measurements, the patch needs to be placed under the arm, just below the armpit.

What is the range for Fever Scout to connect with the smartphone?

As long as the charging dock is near the patch, the Bluetooth can extend up to 100 feet. This range will differ based on location of the patch on the body and surrounding environment that may interfere with the Bluetooth (BLE 4.1) signal.

How long is the Fever Scout battery life?

The battery will last approximately 1 week under constant operation. It is a lithium manganese rechargeable battery and can be recharged on the charging dock.

How do I know if the charger is working?

The LED light will turn on up for 15 seconds when the patch is placed on the charger to indicate that it is successfully charging the patch. When the batteries are low, the LED light will blink for 15 seconds when the patch is placed on the charger.

Can you reuse the Fever Scout Patch?

Yes. We recommend replacing the adhesives on the patch for each use.

How many days can the patch be left on?

Depending on the user, the patch can be left on for one to two days at a time.

Does Fever Scout work with all smartphones and tablets?

Our current software is compatible with iOS devices. Android compatibility will be ready late 2016.

Can I use the Fever Scout App with multiple patches?

At this time, the Fever Scout App only supports single patch monitoring. However, you are able to monitor a single patch from multiple devices using our cloud-based services or using the same account.

Is Fever Scout waterproof?

We do not recommend immersing your Fever Scout in water. Doing so can display inaccurate temperature readings.

Is the patch material safe?

Yes. The materials on the patches are biocompatible, lead-free, and BPA-free.

Is Bluetooth safe?

The Fever Scout uses a radio technology called Bluetooth Low Energy (BLE). The SAR (Specific Absorption Rate) value is around .001 watts/kg, which is less than 1/1000th of the SAR limit for cell phones set by the FDA and FCC. Bluetooth emits much lower levels of radio frequency than smartphones or other Wi-Fi-based devices – the risk is negligible.

Is Fever Scout an FDA registered device?

Fever Scout is an FDA listed device.

Is there a product warranty?

VivaLnk provides a 1-year limited warranty on Fever Scout products. We also provide a 30 day return policy for Fever Scouts purchased directly from VivaLnk.
