Blankie

About

Blankie is a free ambient sound app for sleep and focus. It includes 24 built-in sounds, such as rain, bedroom fans, coffee shops, and brown noise, and you can layer several of them together, adjusting each volume with its own slider. You can also import your own audio files to mix with the built-in sounds.

For bedtime, a sleep timer stops playback automatically after a chosen duration, with a short fade instead of an abrupt stop. Mixes can be saved as presets for sleep or work, and each preset can have its own background photo and accent color. Presets and controls are available through Home Screen widgets, Siri, Shortcuts, Spotlight, Control Center, and CarPlay, and the Mac version can be controlled from the menu bar.

Blankie works fully offline and states that it collects nothing about the user, with no ads, subscriptions, accounts, or tracking. It is available in 12 languages and is developed openly on GitHub.
