A stroke of genius.

eo SwimBETTER are lightweight, wearable handsets equipped with advanced sensors that measure the forces your hands generate and their orientation as you swim – fifty times a second.

Analysing the data produced in the eo app or platform reveals your true swim performance and efficiency by connecting your total effort to the force that is only propelling you forward.

Think of it as a power meter for swimming, only smarter, delivering actionable insights to help you swim better.

eo SwimBETTER was made for:

eo SwimBETTER: The Key to My 800m Bronze

“I have no doubt that using eo SwimBETTER in the lead-up to Paris was a major contributor to cutting 19 seconds off my 800m free time and helping me secure the bronze medal. The data helped me find numerous areas to create efficiencies in my stroke, which clearly showed in my performance and even split.”

Unlocking New Levels with eo SwimBETTER

“The data that I’m accumulating and analysing with eo SwimBETTER is insane. Who would have thought after all this time swimming at the highest level I’d be finding so many areas of improvement? If you’re chasing better performances in the pool, I’d highly recommend the investment.”

Kyle Chalmers

Paris Olympic Ticket

“During 2023-2024 we are adding eo to our swimming program once a week. We keep tracking our girl sprinter, a bit of change in her catch phase, and the direction of her palms during the phase. With better stroke quality we believe that eo is one component that helped our girl drop 0.3 secs and help her get a ticket to Paris 2024. Thank you eo!”

Arwut

Best Customer Service Ever

“The customer service we received from J’Aime at EOLAB was absolutely exceptional—hands down the best we’ve ever experienced. We were blown away by responsiveness, willingness to help, and the timely nature of their assistance. Truly above and beyond. 10/10!”

Matthew

I just did my fastest ever swim

“I just did my fastest 70.3 swim ever (40:41) in Melbourne last weekend. Ended up with my personal best timing, number 1 ironman 70.3 ranking in my age group (60-64) for Indonesia and 209 in the world. Not bad. The whole time during swim I focused on a quick and easy catch to reduce downward pressure and maximize propulsion. Thank you eo SwimBETTER. Pretty incredible.”

Inghie

Immediate benefits and improvements

“After months of video analysis and coaching, I hit a plateau. And one day of using eo and the great feedback from Jaimie to understand all the metrics, I have made improvements in significant areas. The customer service is unbelievable. Zoom calls on a Sunday to explain and guide. I can’t ask for a better experience.”

Brigetta

Detailed analytics to improve your stroke

“Great tool to see where your stroke is inefficient, so you can work on that part to improve your stroke. Jaimie Has been very helpful taking me through my data. I’ve seen great improvements in my speed!”

Erik T

Fantastic tool to optimize the swim stroke!

“I have been using the eo lab swim bands for about 6 months now and recently was able to synch video with the data also. These devices are a game changer from everyone from the beginner to the most elite swimmers. They give insight that you will never see with coaching and video alone and demonstrate it clearly to the swimmer. I highly recommend this product if you want to take your swimming to the next level or if you are a coach and want to take your team to the top.”

Diana

Amazing Data!

“The directional force and propulsion insights from the handsets are also superb. The dashboard provides propulsion values for a swim session, a lap, a stroke, and within a single stroke. Not only the force applied is provided but also the direction of the force and a very precise time of the directional forces within a stroke. Consistency and force vs time are also very helpful views across strokes. It is early days for me but I have been able to make good progress with this data. Regarding support with the handsets, I echo others in that they are superb with very quick response times that address any issues I’m having.”

Frequently asked questions

What is eo SwimBETTER?

eo SwimBETTER is a wearable device that tracks key metrics like stroke rate, distance, and force, providing real-time feedback on your swimming technique.

The device attaches to your hands and measures the force and direction of each stroke. This data is then analyzed and presented in the eo app, providing valuable insights into your swimming performance.

eo SwimBETTER analyses all four swim strokes: freestyle, backstroke, butterfly and breaststroke.

Yes absolutely. We recommend each swimmer has their own membership though because you won’t be able to easily tell data apart if you download multiple swimmers’ data into the same account.

You can watch our explainer video which talks through all the different data and provides some tips on how to analyze your own. We also offer free, one-on-one Zoom sessions with one of our data experts (we call them data whisperers). If you’d like to book one of these sessions, send us an email at: support@eolab.com and we’ll get back to you to arrange a suitable time. Please note, we will need to request access to your data for this session, but it will only be viewed by the data whisperers. There’s also lots of different videos available on our YouTube Channel that provide tips and tricks for recording and analysis.

If you’re just interested in understanding the data from a specific metric, see the broken-down explainer videos below – there’s one for each metric:

Dashboard
Stroke Rate & Force
Force Field
Stroke Path & Hand Velocity
Consistency
Stroke Phases
Force vs Time
Stroke Path & Force

Without a membership you can still record data and access your Dashboard and Stroke Rate and Force data. But if you’d like to access the full suite of eo SwimBETTER data, you’ll need a membership. Your membership provides storage and ongoing access to your historical data and synced videos. It also provides access to all ongoing system innovations, firmware updates and new features. Gold, silver, and team memberships (for six or more swimmers) are available and can be paid on an annual or monthly basis.

Memberships can be cancelled at any time either via your eo Account or by contacting customer service at: support@eolab.com

We’re so sure that eo SwimBETTER will knock your goggles off that we offer a 30-day money-back guarantee. This gives you plenty of time to experience the unique insights and see the results for yourself. If you’re unhappy, just return your handsets to us for a full refund – no questions asked.
