Feature Highlights
All users are part of what we build at Calibrex. Get access to the feature request board as soon as you join.
Guided Workouts
On-demand audio workouts. Anytime, anywhere.
Unlike traditional workout apps, Calibrex doesn't script your workout programs. Instead, similar to a real personal trainer, it adjusts every workout in real-time based on your previous data points and your overarching fitness goal.
Live Rep Data Tracking
Never miss a rep.
Stop guessing if you're working hard enough, going deep enough, resting too long, or training incorrectly.
Calibrex measures everything you do in the gym and makes sure you're always improving based on your overarching fitness goal.
Real-time Audio Feedback
Just put your phone in your pocket and lift.
Coach Cali talks to you through your headphones while you train and tells you what to do next, when to start your sets, and what adjustments to make between sets to get the most from your training.
An AI copilot for your workouts that's just as good as a real-life personal trainer.
Calibrex Score
A simple way to check your performance.
Calibrex encapsulates each set down to one Calibrex score based on your rep speed (power output), tempo (your time under tension), and difficulty (how much harder the last rep was than the first).
Know exactly what you need to improve on without having to get a PhD in exercise science.
Lifting Trends
Your fitness at a glance.
Do you know how much you're really working out? With C3 you'll know exactly how much time you spend lifting each week, how many reps you did, how much weight you moved, which muscles were trained (and which weren't).

Auto Rest Tracking With Audio Cues
Always stay on schedule and keep that pump going.
Calibrex knows exactly when you stop moving and tells you when to start again.
Your Calibrex coach learns from your resting patters and takes it into consideration for your Calibrex scores.
No more scrolling when you should be lifting (unless you want to!)
Muscle Split Tracking & Auto Balancing
