The gap

You can feel something is off. You just cannot see it.

Your coach watches from the deck for a few seconds, then it is the next lane's turn. Underwater cameras and motion labs cost a thousand dollars and live at the national team. Everyone else swims lap after lap with no idea whether their hands are doing what they think.

How it works

Three steps. Then you know.

  1. 01

    Swim

    Slip the rings on your middle fingers and train like normal. The sensors track every stroke underwater, with no buttons and no phone on the deck.

  2. 02

    Dock to sync

    Drop the rings into the charging case after your session. They sync your full swim to the app over Bluetooth in seconds.

  3. 03

    See your stroke

    Open the app for a full breakdown: hand path, symmetry, stroke phases, and one clear thing to work on next.

The hardware

Feels like nothing. Wear it into any public pool.

A soft, sealed ring sized to sit flush on your middle finger. No charging port, nothing to snag on a pull, so you forget it is there until you are out of the water.

The difference

See exactly where your hand goes.

GlideMetrics reconstructs the full underwater path of both hands and lays them over each other. Crossing the centerline, dropping your elbow, pulling harder on one side: it is right there on screen, a picture instead of a guess.

  • Left and right hand path, overlaid
  • Catch, pull, and recovery phase timing
  • One plain-language fix, not a wall of numbers

After the swim

Coaching that actually sticks around.

1

Tips in plain language

"Your right hand crosses the centerline. Enter a little wider." Real cues you can take to the next set, not a spreadsheet you will never open.

2

Watch yourself get better

Stroke score, distance, and consistency tracked over weeks. Streaks and badges that make showing up feel like progress, because it is.

Questions, answered.

Yes. It is fully sealed to 50 metres (5 ATM), well past pool and open-water depth. Wear it in chlorine, salt, or your post-swim shower. There is no port to let water in.
