Available with either a 90 or 15-minute recording capacity, there’s an eo SwimBETTER to suit individual swimmers, squads, teams, long distance swimmers and triathletes.
We love the smell of chlorine in the morning.
eo SwimBETTER starts from US$799 plus eo membership.
14 day money back guarantee | Free express shipping | Free periods apply on some memberships
Analyse, adapt and accelerate your progress with eo SwimBETTER. We’re so sure it will knock your goggles off that we offer a 14 day money back guarantee on every order.
An eo SwimBETTER membership is required for every swimmer to download and store their data. Gold and silver memberships, and team memberships for six or more swimmers, are available and can be paid on an annual or monthly basis. Your membership is automatically activated upon delivery of your order.
Every pair of handsets comes with some free time on your membership.
When you purchase a pair of eo SwimBETTER handsets, we’ll cover some of your membership fees to give you a chance to get the hang of them and understand all the mind-blowing data:
- Six months free on a single membership if less than six memberships are purchased with any pair of handsets – your membership can be purchased at the same time as the handsets or later. If the membership is purchased later, the free period will be added to the first membership purchased on the same account as the handsets.
- One month free on every team membership (six or more memberships) when purchased with any pair of handsets.
Never lose track of your data. Ever.
Your eo licence allows you to download and view your accumulated swim data and keep it all safe and secure in one place. No matter if you leave your team or club, you’ll never lose access. Whenever you want to dive into your data, simply log in to your eo Account.
Product overview
What is eoi?
eoi is our new AI-optimised feature that helps swimmers and coaches unlock the full potential of eo SwimBETTER. Instead of spending hours combing through charts, eoi instantly interprets your freestyle data and delivers an easy-to-understand report with:
- Key insights into your stroke technique
- A prioritised list of areas to focus on
- Recommended drills and videos tailored to you
Current availability
- Freestyle only: eoi reports are currently only available on freestyle data.
- Backstroke & Butterfly: in development and coming soon.
- Breaststroke: will be available once Breaststroke is out of BETA.
Who is eoi for?
- Self-coached swimmers & triathletes: Get fast, meaningful feedback without needing to be a data analysis expert.
- Time-poor coaches: Use eoi to save hours of work. You can make any edits you need to the reports before sharing them with your athletes.
Why use it?
- Focus on what matters – eoi cuts through the noise, showing you only the most important takeaways.

Track your performance in the pool at a glance with a trendline showing your progress over time across a range of different metrics including: Force per stroke, Stroke rate, Distance per stroke, Strokes per lap, Time, Average velocity, and Propulsion.
Watch our video: Dashboard data explained
Improve your efficiency at different speeds.
Measure your total force output alongside your stroke rate and, for the first time ever, see the variations in your force as your stroke rate changes. Push for progress by reducing your force while maintaining the same swim speed and show evolution who’s boss.
Watch our video: Stroke Rate & Force data explained
Swim faster by understanding your force distribution.
See how your force is distributed - helping you adjust your technique and optimise your propulsion by cutting unnecessary force and wasted energy. That's the science of defiance.
Watch our video: Force Field data explained
Hand at the right depth? Pushing across your body? Sweeping too wide?
Pin down where you can progress by tracking the path of your hand through every phase of your stroke - from the front, side, and top down. Identify areas of your stroke that may be compomising your speed and efficiency. With a Gold membership, you can even see your hand speed at any point.
Watch our video: Stroke Path & Hand Velocity data explained
Be better more often.
Consistency is key. Get an instant comparison of yours by selecting any number of your left and right strokes to see an overlay of their paths. Allowing you to identify any degredation under fatigue, changes at varying speeds, and anomalies. Consistency of good technique will get you swimming faster... faster.
Watch our video: Consistency data explained
Identify your propulsive time.
Break down the glide, pull and recovery phases of every stroke to see the percentage of your overall stroke spent in each phase. Optimise your glide and pull phases to level up your swim.
Watch our video: Stroke Phases data explained
Find your missing link.
Dive deeper into your force measurement - pinpointing your strokes strengths and where you're losing force. Seeking that extra level of detail? Get a moment by moment understanding of changing forces within each stroke so you can wave your limits goodbye.
Watch our video: Force vs Time data explained
See exactly where in your stroke you can gain speed.
Map propulsion through your hand path so you can see exactly where in each stroke you’re strongest versus where you may be letting water slip away.
Watch our video: Stroke Path & Force data explained
Seamlessly sync your eo SwimBETTER data with footage of your swim to make diagnosing stroke imperfections even easier.
Simply capture footage of your swim - underwater is best - with any camera and sync it with the data from your handsets. You'll be left with frame-by-frame vision matching exactly to your data giving you unparalleled flexibility in stroke analysis.
Work remotely with a coach? This functionality is a game-changer, that equips your coach with comprehensive insights like never before. They'll feel like they're standing right on pool deck with you.

In the eo SwimBETTER Force Field explainer, you will discover how your forces are distributed across six different vectors. You will also learn how to improve your force distribution to improve swim speed.
Understand how to read your eo SwimBETTER Stroke Path and Hand Velocity data and discover ways to refine your stroke path to improve your force distribution.
Learn how your eo SwimBETTER Consistency data can help you instantly pick up any anomalies in your stroke.
Understand what the eo SwimBETTER Stroke Phases data can tell you about the different phases of every one of your strokes.
The most interesting of the eo SwimBETTER metrics, but often the most daunting, this Force vs Time explainer will help you pinpoint where your stroke’s strengths and weaknesses lie.
Comes with two eo SwimBETTER handsets, a pair of straps, two eo charging clips, two USB-C charging cables, a tiny towel to dry off your handsets, and a storage case.
You can expect around three hours of recording between charges. Your handsets maximise the battery by automatically turning off after 10 minutes of inactivity. Clever.
Fit is based on the width of your palm. You’ll be asked for this measurement at checkout so we can include the correct sized Velcro straps with your handsets.
Your eo SwimBETTER handsets are water resistant to 30 metres / 100 feet and can be used in chlorinated and salt water.
We have two sizes available. Between downloads, eo SwimBETTER90 can record up to 90 minutes of data and eo SwimBETTER15 records up to 15 minutes.
Once you download your data it is immediately deleted from the handset so you can record more data. Your downloaded data is stored securely in the Cloud and is accessible anytime from your eo Account.
Bluetooth®
Each eo SwimBETTER handset weighs in at just 30g / 1.06 oz. That’s about as much as a slice of bread.
Each handset has a charging point on the side. Attach a charging clip to this point, plug in the charging cord then connect into any USBC charging port.
“The ability to measure the forces and direction of forces that an athlete applies to the water is the holy grail of improving elite swimming performance.”
