Sleep analysis help you understand what's going on in your body while sleeping and see if disruptions are occurring.
Remind You to Breathe Well
A normal range of blood oxygen level is the key to starting a new day. Checkme™ O2 ensures you wake up with an energetic morning.
The device will BEEP and VIBRATE when your oxyegn level is lower, or your pulse rate is higher/lower than the threshold you preset, prompting you to change positions for better breathing.
Smart Vibration & Beep
Unlike the traditional sound alert system, it softly wakes you. So sharing a bed with your partner won't affect his or her rest.
You can turn the vibration on or off directly on the device.
Customize your notifications on the app: adjust the vibration intensity and threshold to make yourself comfortable. You can also turn on/off vibration and beep (bibibi).
