First things first: The energy in our inbox lately has been absolutely incredible.

So many of you have reached out to tell us how excited you are to get your hands on the new Calibrex, and honestly, that excitement is fueling us right now. We are just as hyped as you are to get these into the wild.

I wanted to give you a transparent look at exactly where things stand. The great news? The hard part is done. All 𝟮𝟬𝟳 𝗵𝗮𝗻𝗱-𝗯𝘂𝗶𝗹𝘁 𝗖𝗮𝗹𝗶𝗯𝗿𝗲𝘅 devices are fully assembled, tested, and sitting right here in our office.

𝗦𝗼, 𝘄𝗵𝗮𝘁 𝗮𝗿𝗲 𝘄𝗲 𝘄𝗮𝗶𝘁𝗶𝗻𝗴 𝗳𝗼𝗿?
We are currently awaiting the delivery of our brand-new custom packaging. We want your unboxing experience to be just as premium as the device itself, so we are holding tight until those boxes arrive. As soon as they land, we pack and ship.

To make this update a little more personal (and to prove the devices are actually ready!), we wanted to share a photo.

That’s us next to your Calibrex. They are real, they are ready, and they are coming home to you very soon.

Thank you for being part of the Calibrex journey from day one. Keep an eye on your inbox—the next time you hear from us, it will likely be with a tracking number!

Lift with conviction

The first wearable built for lifters.

Limited drop of 207 Calibrex units—hand built right here in midtown nyc.

Most people walk into the gym guessing.

You won’t.

Calibrex gives you a plan going in, real-time coaching while you lift, and the data to show exactly how you’re progressing over time.

Lift with confidence.
Train with intention.
Grow on purpose.

Reimagining personal training with the first wearable designed for lifting.

Live, in-ear coaching. No typing after your set. Calibrex tracks every rep in real time, knows how hard each set is, and gives instant audio and on-screen feedback.

Because Calibrex knows what you did (and how difficult it was), it’s the first fitness app that can truly personalize your training—while you’re lifting, not after.

App-side, a clean analytics page sorts reps, load, velocity, power, ROM, TUT, rest, and set difficulty, tying it to your goals with projected gains per exercise. Keep showing up to realize them. 💪

With over 25M reps tracked, top paid users include Olympians, professional athletes, tech CEOs, and top universities.

Wanted: Elite engineer building at the edge of hardware + AI for lifting. Bonus if you’ve shipped with Expo. DM us or tag a killer below.
