    Remind You to Breathe Well

    A normal range of blood oxygen level is the key to starting a new day. During the night, when your SpO2 started to fall below the preset value, the prompt will be activated. Unlike the traditional sound alert system, it softly wakes you to change to a position that helps you breathe better. So sharing a bed with your partner won't affect his or her's rest. 

    Checkme™ O2 ensures you wake up with an energetic morning.
