Ever wake up in the morning, groggy and disoriented, and fresh and alert other days? While getting more hours of sleep is important, jump starting your day has a lot to do with waking up at the right time. This is all based on sleep cycles you go through, 90-minute periods of light sleep to deep sleep and back to light. Wake up at the end of a sleep cycle during light sleep, and you will feel fresh and ready to start your day. Wake up in the middle of a sleep cycle during deep sleep, and you will feel even more tired and groggy. Use this simple and easy to use app to coordinate your sleep times, and find the best time to sleep or wake up possible!
