If you want to follow a handful of pre set exercises, great. Even that it’s inaccurate in tracking and have to constantly correct the recording. Also the feedback is very unclear. Bunch of charts and numbers but no way to interpret. I returned the device and they were a challenge to work through that. Still haven’t credited my card so I put it into dispute. I think it’s a startup with like 6 people so makes sense, just beware what you are getting into. I like what they are tackling and this will work at some point.

There’s not a single product akin to Calibrex. There have been kickstarters that failed. Calibrex stands in a class of its own it’s brand new yet the owners and founders remain completely dedicated and reachable for feedback, troubleshooting and updates. Which btw there are constant new features. Personally, Calibrex has been the medium That has enabled me to be consistent in my exercise routine for the first time in my life and I’m 40. Prior to Calibrex it was random guessing and failure. Now I use it 3-5x a week with progressive overload tailored to me. Love this device.

The Calibrex app has improved substantially as to where it was in late 2025. I know firsthand, as I submitted literally dozens of enhancement requests to this U.S.-based small startup. The owners reached out to talk on multiple occasions and most importantly, addressed many of the earlier software issues. The customer service is second to none and the accuracy of repetition counting is a 9 out of 10 (I expect it to improve with future updates). Philip and Nick sent me a replacement unit when mine had connectivity issues, and it has worked flawlessly ever since. Shipping was fast and free. This is one of the few apps that when updated in the App Store, I will open it to see the new enhancements page and whatever issues were addressed. Yes, the updates have been that good. I was not compensated for this review.
