Crystal Byte is a nighttime sound recording app designed to help you review your sleeping environment. Simply start a recording before going to bed and place your phone nearby. Crystal Byte monitors ambient sound levels through your device's microphone and generates a nightly summary, sound events, a Quiet Score, and trend reports to help you better understand changes in your sleep environment.
On the Home screen, you can quickly view last night's summary, including your sleep window, Quiet Score, number of sound events, and average sound level. The Reports section provides detailed sound graphs, peak noise levels, quiet periods, and review notes for each recording. In the Sound Events section, you can browse detected events such as peak noises, room sounds, and movement-related sounds, then mark important events or add personal notes.
Crystal Byte also includes history and trend views, making it easy to compare the quietness of different nights, review changes in sound events, and observe bedtime patterns over time. If you create multiple recordings on the same day, the app supports side-by-side comparisons, helping you quickly identify which recording was quieter or contained more sound events.
The app offers both Light and Dark themes for comfortable viewing during the day or at night. The Points Center and VIP Center allow you to unlock enhanced reports, same-day recording comparisons, and additional premium features. Core features—including nighttime recording, report viewing, history review, and trend analysis—remain simple and easy to use, making Crystal Byte a practical companion for continuously reviewing your sleeping environment.
