Rep speed with your sensor.

Train by numbers, not by feel: X-Track measures the speed and range of every rep as you lift, and keeps your whole history on your phone.
-Track turns every rep in the gym into a number you can train by.
Clip the small X-Track sensor to a machine's weight stack or to a barbell and start your set. While you lift, the app shows:
• The speed of every rep (m/s), the moment it finishes
• Range of motion — how far the weight travelled
• Velocity loss across the set, so you know when to stop before your form does
• A live chart of travel and speed
• A rep count as a beep or a spoken number, played over your music instead of pausing it
After the set:
• A summary of every set: best and average speed, range consistency, the full trace
• History per exercise: latest weight, speed over time, working weight over time
• An estimated one-rep max from your load–velocity profile — shown only once there is enough data to trust it
• A calendar of your sessions with weekly and monthly totals
• A body map: tap a muscle to see its exercises and when you last trained it
Also:
• 50+ ready-made exercises across ten muscle groups, and your own
• Log a set by hand when the sensor isn't with you
• Body-fat estimate from body measurements
• Sensor firmware updates from inside the app
• "Find my sensor" for when you leave it at the gym
• Arabic and English, light and dark theme
• Export all your data as a PDF
Your privacy:
No account, no sign-in, and the app makes no internet connection at all. Everything stays on your phone, and you can delete all of it from Settings at any time.
Note: measuring speed and range requires the X-Track sensor. Without it you can still log sets by hand and follow your history.
X-Track is a training tracker, not a medical device.
