Sleep Cycle

Sleep Cycle is a simple time calculator that makes it easy to manage sleep cycles, so that you wake up well-rested. The calculations are based on findings from scientific studies that show the human brain sleeps in cycles of approximately 90 minutes, with the end of each cycle being the best time to wake up well-rested.

Sleep Cycle works in three modes:

- Fixed Wake-up: Allows you to set your desired time to wake up, and suggests the optimal times to go to sleep based on your selection.

- Fixed Bedtime: Similar to above, but instead specifying the time you're going to bed, listing the optimal times to wake up.

- Sleep Now: When you're feeling tired and want to go to bed right away, this mode will display the best times to set your alarm clock to, based on your device's current time.

All three modes can automatically configure your Android alarm clock to the selected time.

睡眠周期是一个简单的时间计算，可以很容易地管理睡眠周期，使你醒了充分休息。该计算是基于从科学研究显示人类大脑睡在约90分钟的周期，每个周期被唤醒的最佳时间充分休息的末端发现。

睡眠周期工作在三种模式：

  - 修正了唤醒：允许您设置所需的时间醒过来，并提出最佳的时间去睡觉根据您的选择。

- 修正睡前：以上相似，而是指定你要睡觉的时候，上市的最佳时间醒来。

  - 立即休眠：当你感到累了，想睡觉的时候了，这种模式将显示的最佳时间你的闹钟设置为，基于设备的当前时间。

所有三种模式可以自动配置的Andr​​oid闹钟选定的时间。
