Whether you’re a lifelong sufferer from a sleep disorder, or one of the crowd who struggles to relax and ease into deep sleep, there’s no reason not to give sleep apps a try, according to Care2.

The busier we get, the harder it becomes to shut down our minds and rest at the end of the day. According to a recent study by the Center for Disease Control and Prevention (CDC), 1 in 3 Americans struggle to get the recommended 7 hours per night of high-quality sleep, turning to Netflix, prescription medications and herbal remedies just to get some shut eye.

Sleep Cycle uses your iPhone’s accelerometer to record your sleeping habits, then pairs this data with sleep cycle theory to wake you up at the ideal time within a 30-minute window. Need to get up at 7am to be out the door in time for work? Sleep Cycle will ring the alarm when the app judges you’re already easing into wakefulness — say, at 6:48, rather than 7:00 sharp.
