REAL-TIME COACHING, PERSONALIZED TO YOU
Get guided through every set with live audio feedback and coaching — tailored to your goals, training style, and performance history.
TRAINING SCORES THAT ACTUALLY MEAN SOMETHING
Every set earns four powerful scores designed to help you lift smarter:
Set Score – How well you executed each rep and how intensely you pushed.
Difficulty Score – How close you came to muscle failure.
Speed Score – How closely your rep speed matched your target training zone.
Tempo Score – How much time your muscles spent under tension.
COMPLETE WORKOUT DATA, TRACKED AUTOMATICALLY
From rep count and rest time to range of motion, power, calories, and velocity — Calibrex 3 captures it all. No clipboard. No guesswork. Just clean, objective data.

Ratings and Reviews
Worst app ever
App is awful, glitches a lot, it would not save workouts, will delete exercises, just bad. It’s like it was created for IOs 2.
The more I try to use this app the more I get frustrated. This is total garbage
