Learn how to use Smart Alarm on your Sony SmartBand. You can set a smart alarm in the SmartBand application. Smart alarms wake you up at the best time based on your sleep cycle.
They notify you with a vibrating alert. The Smart alarm function uses sleep data from your SmartBand over a time span of 30 minutes to wake you up when you reach a state of light sleep.
For example, if you set a smart alarm for 07:00 and your SmartBand is in night mode, it wakes you up sometime between 06:30 and 07:00 when you reach a state of light sleep. If you do not reach a state of light sleep during this period, the smart alarm wakes you up at 07:00. If your SmartBand is in day mode, the alarm alerts you at 07:00.
