Fitbit launched the Planet Fitness Hydromassaging system for its fitness watch in September, a first for an Apple device.
The watch uses a small sensor on the wrist and accelerometer in the back to measure the wearer’s steps and heart rate, and displays that data in an onscreen map.
It also lets you set a calorie and temperature target, and even offers the ability to set alerts if you’re going for a workout.
Fitbit’s Planet Fitness hydromasses use a sensor on a wrist that detects the amount of sweat it takes to keep a user hydrated.
You can get the watch for $299.99.
