Phlex EDGE - Phlex Swim

Phlex EDGE

The EDGE is a premium swimming fitness tracker featuring heart rate feedback, stroke analysis, and professional workout planning in a seamless, goggle worn design.

Simply thread the EDGE onto your goggle strap and wear during any swim workout. Following your workout, the EDGE syncs with the Phlex Swim App to present vital training analytics, log your workout, and provide future workouts.

Due to increased demand, we’ve decided to close EDGE pre-orders until we deliver the product to our early backers. Our current expected shipping date is in July.

How does it work?

It's as simple as threading your goggle strap through the EDGE and going for a swim. The process has been designed to be as simple as possible so that you can focus more on your workout. The EDGE is designed to fit most popular goggles.

Not just a watch

You wouldn't run a marathon in sandals, so why train for swimming wearing a watch. Watches and chest-worn heart rate monitors are cumbersome and bulky, which increases the chances that your stroke will suffer. Lose those inefficiencies and embrace the EDGE technology, a head based, hydrodynamic design that's virtually unnoticeable when being worn.

Train more efficiently

The EDGE actively learns what kind of swimmer YOU are by recognizing workout structure, sets, strokes, and intervals. It even finds inefficiencies in the way you train, then recommends ways to fix them.

Phlex Swim App

Review workout analytics, review your past workouts in the logbook, and even plan your next workout. All in app.

Improve your technique

The EDGE utilizes biometric and inertial sensors to track over 30 swimming metrics during training, which are then interpreted to provide technical analysis and stroke tips post workout.

Stay in your zone

Smart tracking alerts you of your current Heart Rate zone with haptic feedback vibrations. The ability to track your heart rate in real time is THE most important analytic to have during a workout.
