Top Question: Are the magnets strong enough?

We get this question a lot, and we wanted to show you this

That's not your fault! At this time, the Calibrex iOS app is invite only - which means you'll receive an invite once you purchase a Calibrex 1.0

Yes we do! In fact, just over 30% of our existing users are overseas (outside the US).

Absolutely. You’ll be able to export and forward all your data with your coach, instead of simply letting them know how many reps and sets you performed - the coach will have a much clearer view of how well you performed having access to significantly more detailed data.

The Calibrex 1.0 works best with the 3 key fundamental movements: bench, deadlift, squat (and many of their variations) which means as a PLer you'd be able to measure and optimize most of your training.

Tip: After establishing a velocity-load profile, you can actually estimate your daily 1RM instead of prepping for a special testing day that you might not feel 100%.

Absolutely. You can add up to 10 athletes on one device. Switching athletes in between sets is super simple.

Calibrex is a workout tracker that automatically collects and graphs reps, bar balance, and velocity for weightlifters. Two pocket-sized, portable devices magnetically snap on to either end of a barbell and stream workout data to the calibrex app.

Calibrex uses a cutting-edge lidar sensor technology to constantly measure barbell position with mm accuracy. Our power-efficient devices last 2 weeks on a single charge under normal use. Our app uses streamlined algorithms to process barbell data and deliver metrics and feedback in real-time.

Calibrex is for athletes who want to train at their maximum potential. Our goal is to provide a professional athletic coach in your pocket who takes on the burdens of rep tracking, form monitoring, and real-time feedback.

Calibrex tracks weightlifting performance over time for multiple athletes. Realtime graphs and data show live rep ranges, velocity, and bar balance so athletes can adjust on the fly. Audio feedback helps correct lifts and optimize sets. All data is saved and analyzed and can be reviewed at any time by individual athletes and coaches alike to ascertain that athletes are improving optimally.

Calibrex has 3 main advantages over its competitors:

Precision - Our sensor technology takes hundreds of measurements per second at mm accuracy to produce accurate and reliable velocity, range, and balance measurements on every rep.

Portability - We ditched the tether and went wireless. Our slim, pocket-sized devices easily clip on and off any barbell in one swift motion. Strong magnets make sure they stay in place, wherever you go. No need to anchor yourself to a platform, Calibrex is part of the bar.

Feedback - Our system is designed to be your strength training coach. During a set, our app provides you with real-time audio feedback to keep you training at peak performance. Know your balance, rep quality, velocity, and rest times without a training partner.
