How do I add my coach as an athlete?

arrow rightarrow right

Ask your coach to create a free account at app.phlexswim.com and invite you to their group via email.

How does Phlex track open-water swimming?

arrow rightarrow right

Since the Polar Verity Sense device doesn't have a GPS sensor, we use an AI model that calculates the distance swum in open water using stroke data.

How long does it take to sync a workout?

arrow rightarrow right

Syncing one hour's worth of swimming takes approximately 1-2 minutes for iOS and new Android phone users. Older Android phones may experience longer offloading times. We are working with our partner Polar to optimize the experience.

What do I need to do if I already own a Polar device?

arrow rightarrow right

You can join the platform on a software membership only and start your subscription with a 30-day free trial. Please make sure that your device firmware is up-to-date (v.2.1.0) before you start. You can update your device via the Polar Flow app.

What is Phlex PRO?

Phlex PRO is a desktop app that offers coaches and athletes a detailed view of their workouts and training progress. Athletes can sign in to their account at app.phlexswim.com, and coaches can create a free account and invite their athletes.

What's the difference between the Polar Verity Sense device and the Apple Watch when it comes to swimming tracking?

arrow rightarrow right

The main difference is heart rate accuracy. The head-worn device that sits tightly on your temple provides highly accurate heart rate readings. While the Apple Watch also offers good quality heart rate data, the water that can get in between the wrist and the sensor can lead to poor heart-rate accuracy.

When will Apple Watch compatibility be available?

arrow rightarrow right

We are in the final stages of the project and plan to release the Apple Watch integration by the end of October. We are currently in beta. Sign up for our newsletter to be notified of the release.
