About
MySwimEdge combines a waist-worn inertial sensor with a mobile analytics app to give freestyle swimmers and their coaches an unprecedented level of stroke-by-stroke insight. The sensor records data continuously during a lap; after pressing a button the swimmer receives a detailed breakdown in the app within minutes—no manual video review required. The platform delivers 8 unique metrics per lap including average stroke time (left/right), distance-per-stroke (left/right), average maximum speed (left/right), and average minimum speed (left/right). At the stroke level, each individual pull is profiled for DPS, min speed, max speed, timing, and per-cycle stroke rate. Three proprietary graphs make patterns visible at a glance: a within-lap speed-change graph that reveals consistency trends, a cross-lap left-arm vs. right-arm comparison graph to identify asymmetry, and a stroke-pattern overlay graph for technique repeatability analysis. The tool supports hypothesis-driven coaching: every technique adjustment can be measured in the next lap, turning subjective feel into objective data. National triathlon coaches from Germany and Scandinavia, Olympic and Paralympic champions, and NCAA university swimmers have used MySwimEdge to identify imbalances, reduce fatigue, and target gym work precisely. It is equally valuable for triathletes who need efficient open-water freestyle and for pool programs focused on performance optimisation.
Key Features
- 8 Unique Lap-Level Metrics: Calculates average stroke time, distance-per-stroke, max speed, and min speed independently for left and right arm strokes every lap.
- Stroke-Level Granularity: Profiles each individual pull for DPS, minimum speed, maximum speed, stroke timing, and per-cycle stroke rate—not just lap averages.
- 3 Proprietary Speed Graphs: Visual graphs show within-lap speed changes, left vs. right arm stroke overlays, and cross-stroke consistency patterns to reveal asymmetry and fatigue.
- Waist-Mounted Sensor Hardware: A compact sensor worn on a belt collects inertial data during the lap and transmits results to the app after a single button press—no camera or lane equipment needed.
- Fact-Based Technique Iteration: Every hypothesis about a technique change can be tested immediately in the next lap, enabling in-session adjustments grounded in objective stroke data.
Use Cases
- A triathlon coach uses lap-by-lap left/right arm speed data to identify and correct stroke asymmetry before a key race, preventing the 30–40 m drift that leads to early fatigue.
- An NCAA university swimmer receives post-lap data showing weak pull power on one side and uses the insight to target specific gym exercises, improving stroke propulsion over the season.
- A masters swimmer tests a new hand-entry technique tweak in real time during practice and compares the DPS and max-speed metrics before and after to confirm whether the change is beneficial.
- A national triathlon program integrates MySwimEdge 2–4 times per month per athlete to track long-term consistency improvements and benchmark technique across the squad.
- A self-coached competitive swimmer uses the speed-change graphs to identify a mid-lap deceleration pattern, then adjusts kick timing and measures the effect in the following lap.
Pros
- Unique Left/Right Arm Asymmetry Detection: Independently tracking each arm uncovers imbalances that accumulate over race distances (e.g., 30–40 m drift in a 400 m event), which conventional lap timers cannot reveal.
- In-Session Feedback Loop: Results are available within minutes after each lap, allowing coaches and swimmers to adjust technique during the same training session rather than reviewing footage afterwards.
- No Lane Infrastructure Required: The self-contained sensor and belt system works in any pool or open-water setting without cameras, underwater hardware, or timing gates.
- Validated by Elite Users: Adopted by national triathlon coaching staffs and Olympic/Paralympic champions, lending credibility to the metrics and the coaching workflow it supports.
Cons
- Freestyle-Only Analysis: The platform currently focuses exclusively on freestyle stroke analysis, so swimmers who also compete in backstroke, breaststroke, or butterfly get no insight for those disciplines.
- Hardware Purchase Required: Using MySwimEdge requires buying a physical sensor in addition to the app, making the entry cost higher than software-only analytics tools.
- Single-Lap Test Protocol: Each analysis is triggered manually after one lap, which may disrupt longer continuous training sets and requires the swimmer to remember to press the button consistently.
Frequently Asked Questions
Where is the sensor worn during swimming?
The sensor is placed on the swimmer's waist using a dedicated elastic belt. It records inertial movement data throughout the lap and is activated/deactivated by pressing a button on the device.
Does MySwimEdge work for open-water and triathlon swimming?
Yes. The waist-belt form factor is suitable for both pool and open-water use, and the tool has been specifically tested with national triathlon coaching teams for race-preparation analysis.
How long does it take to receive analysis after a lap?
After pressing the button at the end of a lap the sensor processes the data on-device; the detailed stroke analysis typically appears in the companion app within a few minutes.
What metrics are measured at the stroke level?
For every individual left and right arm stroke the app reports distance-per-stroke, minimum speed, maximum speed, stroke timing, and the stroke rate for each left-right cycle pair.
Is MySwimEdge suitable for beginners or only elite swimmers?
While it has been adopted by Olympic champions and national team coaches, any swimmer or coach who wants data-driven feedback on freestyle technique can benefit. The graphs and metrics are designed to surface actionable insights regardless of performance level.
