The Xtrack sensor sitting on the top plate of a gym machine weight stack.

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.

Early bird: 2,000 EGP with free shipping for the first 50 orders — then 2,500 EGP plus 100 EGP shipping. Delivery starts 15 November.

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.

See it in use

A real set, start to finish.

Recorded on a test unit. No sound needed — here is what happens:

  1. 01A 3-2-1 countdown while you get into position.
  2. 02Each rep appears as you lift it: rep count, range of motion and velocity loss, live.
  3. 03Rep speeds stack up along the bottom, slow reps flagged.
  4. 04When you stop, the set summary: best and average velocity, velocity loss, range of motion and the full speed trace.

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

In the app

More than a rep counter.

A card after every set.

Finish a set and the app tells you what it saw: a new record, a strong set, or a push to keep going. Records get their own colour, so you know before you read.

Cards from the Xtrack app.

  • You have a new record
  • Fastest at this weight
  • Strong set
  • Iron
  • Clean work
  • Keep going
  • You've got this
  • Next one's better
  • Rep beep

    A short tone after every counted rep, so your eyes stay off the phone. It mixes with your music instead of pausing it.

  • Body composition

    Log neck, waist and hip measurements with a tape and follow your body-fat estimate as a trend over the weeks.

  • Suggested sessions

    Answer two questions and the app suggests a push, pull or leg day from what you've logged, with sets, reps and a starting weight. A suggestion, not a prescription.

  • Max-weight histogram

    Your heaviest weight on each training day, one bar per day, with a smoothed trend line on top.

  • Performance chart

    Training quality over time for each muscle group, with which way each one is heading.

Questions

Before you ask.

When will it ship?

Delivery starts on 15 November 2026, inside Egypt. We call every customer to confirm before their order ships.

How much will it cost?

2,000 EGP with free shipping for the first 50 orders — the early-bird price. After that, 2,500 EGP plus 100 EGP shipping to any governorate. Prices include VAT.

How do I pay?

By InstaPay when you order — upload a screenshot of the transfer — or cash on delivery. There are no card payments on this site.

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?

The first batch ships inside Egypt only, to every governorate. Other countries will follow.

Can I return it?

Yes: within 14 days of delivery if it is unused and in its original packaging, and it comes with a 6-month warranty against manufacturing defects. Details are in Shipping & returns.
