Night Signal Radio
A generative sound machine for iPhone. It composes endless ambient music on the device, in styles from synthwave to Berlin School, and keeps playing with the screen locked.
Status: in private beta on TestFlight, by invitation. It is not on the App Store yet. Needs an iPhone with iOS 26 or later.
What it does
- Makes its own music in real time. Nothing is streamed or looped from a recording.
- Pick a mood, a place and a style, or let the wizard choose for sleep, focus or company.
- Works offline. No account, no ads, no tracking.
- Plays in the background and on the lock screen, with a sleep timer.
- Adjustable text size, in English and Spanish.
Music, weather and more
- Music: the radio plays styles from synthwave to Berlin School, in moods you can tune, or build your own station with the wizard.
- Weather: rain, wind and thunder, with a Preview to hear the weather on its own and a button to fire a single thunder strike.
- Share and undo: share a sound as a text code, and undo or redo any change.
Private by design
The app uses no network, no account, no analytics and asks for no permissions. Everything stays on your iPhone. Details are in the privacy policy.
On your home screen
The app is called Night Signal Radio. Its icon label on the home screen reads Night Signal so the whole name fits.
