Measure every rep.

Know if today's set was actually better.

A sensor that measures how fast the weight moves, so you can train on data instead of feel.

The problem

You can't feel bar speed.

Same weight, same reps, completely different session. Bar speed is the difference between a set that built something and a set that just made you tired — and it's the one thing you can't feel reliably.

How it works

Two seconds to set up. Every rep measured.

  1. 01

    Attach it.

    Magnets onto the weight stack, or clamp to the bar. Two seconds.

  2. 02

    Lift.

    It tracks every rep — distance, speed, where in the movement you're slowing down.

  3. 03

    See it.

    Live on your phone, and saved so you can compare against last week.

A real set, start to finish.

What it measures

Every rep, broken down.

  • Mean concentric velocity, per rep
  • Peak velocity and where in the range it happens
  • Range of motion, and how consistent it is across the set
  • Velocity loss across the set
  • Rep count and time under tension

Questions

Before you ask.

When will it ship?

We're aiming for 15 November 2026 in Egypt, and 1 January 2027 for the wider MENA region. Those are estimates, not promises — the waitlist hears first if they move.

How much will it cost?

We'll share pricing with the waitlist first.

Does it work on machines, or only barbells?

Both. Machines are the main use — it magnets straight onto the weight stack — and it clamps to a barbell too.

Do I need a subscription?

Not for the core app.

Which phones does it work with?

iOS and Android.

Where do you ship?

Egypt first, then the wider MENA region from January 2027. Somewhere else? Join the waitlist and pick "Other" — it tells us where to go next.
