Sleepbox: Offline Sleep Sounds

Sleepbox is an offline sleep sounds app designed for difficult nights. It helps you relax, slow down your thoughts, and fall asleep with layered soundscapes stored on your device. Each soundscape has adjustable layers, letting you tune the main sound, low body, and distant atmosphere to your own sleep rhythm. No account. No ads. No tracking. No sleep recording. No data collection. All sounds are stored on your device and work completely offline. Sleepbox is not a sleep tracker, not a meditation platform, and not a regular music player. There is no progress bar, playlist, album cover, previous track, or next track. It is a quiet little box for the nights when your mind will not stop. Sleepbox is a US$1.99 paid App Store download. After purchase, all offline soundscapes and sleep features are available permanently. No subscription, no in-app purchases, no account.
