Q Score
One number.Your whole day.
Sleep, vitality, and movement don't happen in isolation — they add up. QALO reads all three and turns them into a single Q Score each day, so you know at a glance whether today is a day to push or a day to rest.

What goes into your Q Score
Q Score
One score, built from your sleep, stress, vitality, and movement the day before. See an 84 and you know you're set up to perform. See a 62 and you know today calls for an easier pace. Either way, you're not guessing.
Sleep
The foundation. QALO scores your total sleep, your stages, and how efficiently you slept — because a night that looks long on paper can still leave you flat.
Vitality
Your body's real-time readout. Resting heart rate, HRV, blood oxygen, and skin temperature — the four vitals that tell you how recovered you actually are, not just how you feel.
Movement
Steps, active calories, and exercise time, rolled into one number so a good day doesn't hinge on hitting a single step count.
Your whole day
Summed
up in one number
The Q Score distills thousands of biometric data points across sleep, heart rate, and movement into one simple daily metric.
We spent over half a million hours analyzing human performance so you don’t have to spend a single second guessing your readiness. We’re here to help make every day count.

“So far, I’ve had it for less than a week, but I really love having an alternative to wearing an Apple Watch everywhere I go. Especially when I sleep to get my metrics. Wish I would’ve bought one of these years ago. 100% recommend to anyone.”
