A longer view of improvement

Don’t just measure a swim. Track the swimmer you’re becoming.

A single swim is a snapshot. A history of repeat assessments, stroke trends and coach observations can help you understand what is changing across weeks and months.

  • Compare technique and consistency over time.
  • Keep repeat tests and training context together.
  • Connect sensor trends with video and coach notes.

Look for patterns. Test a change. Review the next swim.

A few useful answers

Before your next step.

What is the difference between Sense, Motion and Motion Pro?

Sense is one head sensor for everyday swimming insights. Sense Motion adds one movable pod for targeted wrist, ankle or hip assessments, one placement at a time. Sense Motion Pro combines the head sensor with five synchronised Motion pods for six measurement points and simultaneous full-body analysis.

Do I need to wear a watch?

Sense is being designed to record your swim without a watch. The intended workflow is to swim with the sensor, sync after the session, then review the analysis in DuoSwim. Device compatibility and sync requirements will be confirmed before launch.

Which measurements will be available?

The page shows the areas we are developing, including stroke rhythm, consistency, turns and movement analysis. Supported metrics, accuracy and compatibility are subject to hardware and software validation. The example dashboards use illustrative data, not results from a finished device.

Can one Motion pod analyse the whole body at once?

No. Sense Motion uses one movable pod for a targeted assessment at the wrist, ankle or hip while the head sensor stays in place. Motion Pro is the six-sensor system designed for simultaneous analysis across the body.

When can I buy Sense, and what will it cost?

Launch dates, hardware prices, bundle savings and any software or subscription requirements have not been finalised. Join the waitlist for product updates, including availability in your region and club or team purchasing.
