Abbas Karimi - Para Olympian, World Championships Medalist

Before Phlex, there was never an option that provided me the ability to track my training with so much detail. I find myself checking my scores every day after training. Seeing my improvement so simply defined has been a physical and mental relief.

Phlex helps me push. I get feedback that shows me what to work on next.

Phlex accurately tells me what my heart rate was throughout my session. It breaks down the sets and gives me times for each part of the workout.

Cody Miller - Olympic Medalist, Swimming Vlogger

I use Phlex to monitor my taper because it tracks everything I’m doing leading up to a meet. I look at my stroke trends and heart rate on all pace sets.

Phlex allows me to do things I haven’t done before. It brings joy.

Darra Torres - 5-time Olympian and Bestselling Author

Swimming has always been a love for me. I think it’s even more so now because I don’t have to keep track of what I’m doing. Phlex does the work for me, making swimming much more fun.

Darra Torres - 5-time Olympian and Bestselling Author
Harold Primat - Former Formula Driver, Triathlete

Phlex keeps detailed recordings of all my swimming sessions. Nothing is missed, and I know exactly what strokes I did during each workout. It also shows me the intensity of my sessions and gives me the total of my monthly distance. I can swim fully relaxed, knowing Phlex does the counting for me. I am now fully addicted and cannot imagine swimming without my device anymore.

Jason Lezak - Olympic Gold Medalist

Phlex is the perfect tool for educating yourself about your body. Once I gained a better understanding of myself, my training approach changed. When I was a kid, there wasn’t much thought put into what we did in practice. We focused on repetitions instead of the details that would really make us faster in competition. Later in my career, I started to pay more attention to stroke data, physiology, and recovery. It became less about just doing and more about improving my race weaknesses.

Jason Lezak - Olympic Gold Medalist
Jazz Carlin - Olympic Medalist

Distance swimming has always been a huge part of my life. What I love most about Phlex is that you always get insightful feedback. Reading through pace charts and seeing my overall improvement so clearly has really changed my relationship with training.

Marty Hendrix - Masters Coach

As a USMS coach and a Masters swimmer myself, I know how important it is to maintain a safe training environment for my athletes, regardless of age. Phlex gives me the ability to monitor my athletes from a distance or work closely with those who have health concerns. It’s given me peace of mind and more confidence to provide each individual with their own version of training.

Marty Hendrix - Masters Coach
Paul Pesqueira - Fitness Swimmer

I love the data and the feedback that helps you improve your performance. It’s remarkable. I have been swimming for many years, from High School to Masters Swimming and Phlex has allowed me to work on various aspects of my swimming. I would encourage any swimmer from elite to novice to try this product.

Ron Aitken - Olympic Coach For Team USA

I’ve been using Phlex technology every day for over 2 years. What we love about it is the ability to personalize the training for each athlete and see how they are progressing throughout the week. It also gives me the right data to monitor if I’m not overtraining my swimmers and when to give them opportunities to recover.

Ron Aitken - Olympic Coach For Team USA
Stephan Barmentloo - Fitness Swimmer

I'm a recreational swimmer and not a member of a swim club. Phlex provides me with the incentive to go swimming on a regular basis. Phlex tracks every lap, movement, and heartbeat and converts it into a wide array of statistics that can be reviewed after every session. Comparing sessions and seeing the progress I make on a physical but also technical level gives me a lot of motivation to keep going at it and live healthily.

Vincent Lam - Age Group Swimmer’s Parent

The precision of Phlex enabled us to train our son under the USRPT program for the past few years. The cloud service enabled us to monitor our son's progress, whether he trained with his school swim team or us. The heart rate monitor allowed us to modify the training program in real-time if needed, a valuable tool for any swimmers.

arrow rightarrow right

We recommend using the included mesh storage bag to keep your Verity Sense and Goggle Clip together.

Is Phlex only for professional swimmers?

arrow rightarrow right

Absolutely not! Whether you swim for fitness, the thrill of competition or love of gliding through the water, ask yourself these questions: Are you an ambitious swimmer? Do you want to get the most out of each and every swim? And would you like to become faster, more agile, more intelligent with every stroke? 

If your answer’s ‘yes’ then phlex is for you!

Is my watch compatible?

arrow rightarrow right

You can check the most up-to-date list of compatible devices here.

My watch already tracks swimming. Why should I use Phlex?

arrow rightarrow right

Good question! Truth is, the watch market has become saturated with high-quality hardware from a wide range of manufacturers – but the swimming experience with these devices is severely lacking…

First, they lack accuracy in tracking the foundational parts of a swimming routine, such as workout times, distance, or workout breakdown. (And chances are, they will completely ignore core stroke metrics such as rate, distance per stroke, and stroke efficiency).

Secondly, most apps track general metrics – they do not go into the multi-layered nature of swimming (and nor are they designed by people who love the sport as much as we do!) 

Most importantly, they do little to provide you, the swimmer or coach, with any kind of actionable insight to build and improve upon.
