SLEEP
Sleep Smarter.Recover Better.
QALO reads every stage of your night and turns it into one Sleep Score, plus the why behind it, so you can wake up genuinely recovered.
[ - Features - ]
Everything your night is made of
Sleep score
One number that makes sense of your whole night. Your Sleep Score weighs how long you slept, how much time you spent in each stage, how quickly you fell asleep, and how often you woke — so you know at a glance whether last night helped you or cost you.
Sleep stages
Light sleep is the on-ramp. Deep sleep is the repair shop. REM is the mental gym. QALO tracks all three — plus time awake and naps — so you can see which part of your recovery is thriving and which is falling short.
Efficiency & Latency
Efficiency is how much of your time in bed you actually spent asleep. Latency is how long it took you to get there. Together they reveal the two most fixable sleep problems — the restless night and the racing mind — and let you watch both improve as your habits change.
Flexible Sleep
Not everyone sleeps 11 to 7. QALO's flexible sleep detection tracks split nights, naps, and non-traditional schedules — built with night-shift workers in mind, not as an afterthought.

“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.”
