Soak: Sleep Wakeup to Videos is an iPhone app developed by Andrew Bespaly. This free app falls under the Lifestyle category and offers a unique way to start and end your day. With Soak, you can choose any YouTube video to wake up to or fall asleep with.

The app allows you to create and save playlists, so you can have multiple videos play for a single alarm or sleep session. It also offers automatic video looping, ensuring that you don't miss the alarm if you haven't woken up during the first playthrough or if the sleep video finishes while the timer is still running.

One of the standout features of Soak is the gradual volume increase for the alarm. The alarm video starts at a very low volume and gradually gets louder until it reaches maximum volume, ensuring that you wake up on time. You can even customize the time it takes for the alarm video to reach maximum volume.

Additionally, Soak offers a snooze button with adjustable snooze duration, allowing you to go back to sleep for a set number of minutes before the alarm rings again. The app also allows you to select a specific time for a video to start at, giving you full control over your wake-up and sleep experience.

Please note that Soak requires an internet connection to function properly.
