App Description

Wake up gently, track and improve your sleep. Feel refreshed and rejuvenated every morning!

Tired of being jarred awake? Wake up to over 750 high-quality natural sounds from around the world. Create your own perfect wake-up sequences of 6 different natural sounds. You could begin with soothing rain, progress to ocean waves and morning bird calls, and, if those don't work, be roused by Japanese drums and rolling church bells.

With over 750 sounds and fully programmable play times, you have virtually endless possibilities to customize your wake-up experience. You’ll start your day well-rested and full of energy.

Want to get 7, 8 or more hours of sleep every night? Sleep Science tracks your sleep each night and helps you achieve your personal sleep goal.

Want to understand your sleep over time? Sleep Science provides meaningful graphs over weeks, months and years so you can see how your sleep improves.

Want to learn what affects your sleep? Sleep Science lets you record notes about changes in bed-time routine, exercise, stress, and more. You can even put notes on your sleep graphs.

Not sure what wakes you up? Sleep Science records the loudest sound during the night so you can find out.

Do you forget your dreams? Sleep Science lets you record dreams during the night or when you wake up. You can review them weeks, months or years later.
