Phasewake uses your heart rate and movement to find a better moment to wake you. A gentle vibration on your wrist helps you wake during lighter sleep.
Starting at 7:30, your watch measured movement and heart rate every 30 seconds. At 8:02, it detected a promising moment to wake you and triggered the alarm 58 minutes before your latest wake-up time.
Unlike microphone-based sleep apps, Phasewake measures movement and heart rate directly from your wrist. A gentle vibration helps wake you without unnecessarily disturbing your partner.
Your watch finds a suitable wake-up moment, but your phone sounds the alarm. Leave it in another room, and you'll have to get out of bed to turn it off. You can still manage your alarms directly from your watch.
After you dismiss the alarm, your watch asks, “Are you awake?” and monitors your movement for five minutes. If it detects no movement or steps, the alarm goes off again.
If no suitable wake-up moment is detected, the alarm goes off at your latest scheduled time. If your phone is unavailable or its battery is dead, your watch can wake you instead.
Start a nap directly from your watch and get comfortable. Phasewake estimates when you fall asleep and aims to wake you about 20 minutes later. If sleep isn't detected, your alarm goes off at the latest time you've chosen.
Every alarm with a wake-up window creates a chart showing your heart rate, movement, and the moment your watch chose to wake you. Review your recent mornings and see how often Phasewake found a suitable moment.
Phasewake requires no account and never uploads your sleep data to its own servers. Your watch and phone communicate directly, and sensors are active only around your scheduled alarm or during a nap you start.
Choose your alarm time and a window of up to 60 minutes in which your watch can look for a better moment to wake you.
Thirty minutes before your wake-up window, your watch begins measuring movement and heart rate every 30 seconds to estimate your resting heart rate for the night.
Phasewake looks for signs of lighter sleep within your chosen window. If no suitable moment is detected, your backup alarm goes off at the latest scheduled time.
