What is Calibrex?

Calibrex 2 is the first exercise tracker designed for physical exercise.

We've found that most fitness trackers focus mainly on cardiovascular metrics and steps but nothing that can really help us understand our progress in the gym. Calibrex brings technology that currently only pro athletes in pro sports facilities have, in a portable and affordable form factor.

How long does the battery last?

The battery is designed to last about one week or 4 one hour sessions.

Do you have a warranty?

Every Calibrex 2 comes with a Calibrex™️ 1yr warranty.

We back our Calibrex devices with a one year warranty, ensuring that any issues or problems will be promptly resolved.

This warranty is applicable if you purchased your Calibrex device directly through us and have an active membership. In such cases, our team will replace your device without any additional cost.

How fast does it charge?

Calibrex 2 charges in 30'-45'.
