Now on Apple Watch
Wake up at 7:00.
Not 6:47.
Other smart alarms fix grogginess by waking you early. WakeZ reads your sleep stage in real time and gently guides you into a lighter stage with personalized taps on your wrist, so you wake exactly when you planned, and every minute of sleep stays yours.

The smart alarm trade-off nobody talks about.
Here’s how every other “smart” alarm works: you set 7:00, and it opens a 30-minute window. Somewhere between 6:30 and 7:00 it guesses you’re in light sleep and rings. Sometimes that’s 6:47. Sometimes 6:33.
That’s not intelligence. That’s a compromise, and you’re the one paying for it, 13 minutes at a time.
–27 min
The sleep debt a 30-minute smart-alarm window can quietly build over a single week.
2–4 hrs
How long sleep inertia, post-wake grogginess, can measurably impair alertness and attention.

Control you have over the actual moment you wake up. An algorithm decides for you.
We don’t move your alarm.
We move your sleep.
Real-time, not retroactive
At 6:30 your watch starts classifying your sleep stage live, second by second, on-device. Not a chart you read the next morning.
Sub-perceptual haptics
Calibrated vibration sequences, tuned below the threshold that would wake you, nudge your nervous system from deep or REM toward a lighter stage.
Your time, exactly
By 7:00 you’re already near the surface. The alarm doesn’t have to jolt you, it just finds you there. 7:00 means 7:00.
30 minutes, one night, step by step.
This is what actually happens between the moment WakeZ starts listening and the moment you open your eyes.
- 6:30
Monitoring begins
Your Apple Watch is already streaming heart rate, heart-rate variability and motion. WakeZ starts classifying your stage in real time. No haptics yet: first it listens.
- 6:35
REM detected
You’re in REM. Waking here means vivid disorientation. WakeZ delivers a short, low-amplitude haptic sequence, the pattern calibrated for a REM-to-light transition.
- 6:48
Drifting toward light sleep
Stage transition confirmed. WakeZ eases off. If you slip back into deep sleep, the sequence re-engages automatically.
- 7:00
You wake up
Light stage, on schedule. The wake haptic escalates gradually, from barely-there to unmistakable, over a few seconds. No alarm sound required.
Every night is different. The sequence adapts to what your body is actually doing, not to a fixed script.
Why “smart” hasn’t meant smart until now.

For the curious
The science underneath.
WakeZ isn’t an idea invented from nothing. It’s the convergence of three well-established areas of sleep research, made practical on hardware you already wear.
Wellness disclaimer. WakeZ is a wellness product. It does not diagnose, treat or prevent any medical condition, and its outputs are not a substitute for clinical sleep assessment. If you have persistent sleep problems, snoring with pauses in breathing, or excessive daytime sleepiness, speak to a doctor.
The alarm is the start of the morning. Not the end of the product.
Full sleep architecture
Awake, Light, Deep and REM, night by night, plus a daily Sleep Score that shows your trend rather than a single number in isolation.
Wellness check-ins
A short daily questionnaire connects how you slept to how you actually feel: mood, energy, focus. Over weeks, the correlation becomes the insight.
Apple Health, in sync
WakeZ reads from and writes to HealthKit, so your sleep data lives where the rest of your health data already is.
What you need
Apple Watch watchOS 9.0 or later. Required for sleep tracking.

That’s it. No extra hardware, no bedside device, no subscription to start.
