Available on Ios & Android App Stores
In-depth training feedback

Calibrex 2 tracks your reps, daily readiness, and power to deliver actionable insights on how you can optimize your training and get stronger, faster.

Over 1 million reps tracked and analyzed so far! The Calibrex 2 is the size of a battery, attaches to just about anything, and can track workouts beyond the weight room. HIIT workouts, pull ups, push ups, jump squats. You name it, we can track it.

Get more out of your training

Calibrex tracks rep speed, power and balance, and gives real-time audio feedback via sound. Two types of sounds let you know if you're lifting faster or slower than your previous rep, and alert you if you get out of balance.

It's important to know how well you're performing on the same weight week over week. Are you lifting the same weight faster or slower? Our color system lets you know if you're on track, if you're ready to level up the weight, or if you should take it easy for the day.

Manipulate different rest and recovery points and find out what works best for you. Research shows that more work does NOT lead to better performance results.
An athlete before a competition is not going to want to go all out, compared to his or her prep season. 

Do you time your rests between sets? Probably not, because it's a hassle. We make it easy by doing it for you. Optimize your performance by resting just the right amount.
