When it comes to fitness tracking, runners and bikers seem to get all the fun gadgets, but Misfit has a new device aimed at swimmers.

Misfit teamed up with Speedo to launch a new fitness tracker with swimmers in mind. The Speedo Shine, unveiled on Tuesday, will be available online and in Apple Stores starting Sept. 1 for $79.99.

"Speedo Shine tracks a swimmer's lap count and swim distance with industry-leading accuracy and works for all stroke types," the companies said.

The Speedo Shine is waterproof to 50 meters, and syncs with the Misfit app for iOS and Android to display your laps, swim distance, calories burned, and points earned. You can also wear it outside of the water to track your walking, running, cycling, and sleep.

The device uses a "3-axis accelerometer" that gathers data on movement in three different directions. Proprietary algorithms designed by Speedo and Misfit take this data and turn it into the info you see on the app. Speedo tested for the device at its Aqualab in Nottingham, England where the company develops its swim suits.

Made out of "aircraft-grade aluminum," the Speedo Shine is super-thin, measuring in at just 8.8mm and 3.3mm at its edge. It comes in a "unique pale silver color" the companies are calling "Pure" and is boxed with a white sport band, black sport band, a clasp, and an action clip.

Even better — it never requires charging. It runs off a basic watch battery that lasts for up to six months, and syncs directly to your phone via Bluetooth — no dongles or a computer necessary.

The Speedo Shine already has one high-profile fan — Olympic Gold Medalist Missy Franklin.

"One of the most difficult parts of swimming for fitness is keeping track of laps and the Speedo Shine eliminates that challenge," Franklin said in a statement. "With the Speedo Shine, you can focus on getting the most out of your water workout and it's also a great looking accessory to wear."

The Speedo Shine will initially be available exclusively at Apple retail stores worldwide, as well as misfit.com and SpeedoUSA.com. The device will launch at additional retailers later this year.
