How It Works
You tried logging food manually. You quit. Everyone does. Crux works because you do not have to think about it.
A lightweight band that sits on your wrist all day. Comfortable enough to forget it is there.
Press the button before your meal. The camera captures your food and AI estimates calories in seconds.
Calorie count appears right on your wrist. No phone, no database, no guessing portions. Just data.
Wear it. Click it. Done.
The Band
Crux is not another smartwatch trying to do everything. It is a purpose-built calorie tracker with a camera, a button, and a display. That focus is what makes it work.
Band + App
See your daily calories right on the band. When you want the full picture, the companion app tracks your history, streaks, and progress toward your goal.
The band does the hard part. The app is there when you want to go deeper.
Limited Early Access
Be first in line. No commitment. Just priority access when we launch.
