Click to learn about Spree’s unique features:

The First and Only

There has never been a fitness monitor that measures the key element of body temperature and incorporates it into your workout – until now. Having this knowledge at your fingertips creates a new benchmark in training.

You’re Warming Up

Make your gym teacher proud and warm up to prevent injuries from overextending any unprepared muscles. Spree will show you exactly when you are in your optimal body temperature zone.

Completely Non-Invasive

Using a unique patented technology, Spree has found a way to monitor your body temperature externally from your forehead. We figured you didn’t want to work out attached to wires or worse – an internal probe.

Too Darn Hot

Overheating can lead to heat exhaustion and heat stroke. The Spree app will alert you when you are out of your optimal body temperature zone. We’re happy to save your life.
