CalmTone432 is a simple, focused sound app designed to help you relax, unwind, and create a peaceful listening environment. It generates continuous calming tones and binaural beats that you can adjust and combine to suit your personal preferences — whether you’re winding down for the night, focusing quietly, or taking a moment to reset.

The app is intentionally minimal. There are no accounts to create, no feeds, and no distractions — just sound. CalmTone432 works entirely on your device and gives you control over tone, volume, and playback duration, so you can shape the experience without interruption.

You can use CalmTone432 with headphones or speakers, for short sessions or extended listening, and even set it to turn off automatically when you’re ready to sleep.

CalmTone432 does not track you, does not require sign-in, and does not send analytics or personal information anywhere. Once installed, it works fully offline.

Whether you’re creating a calming background, focusing on a task, or simply enjoying ambient sound, CalmTone432 keeps things straightforward and under your control.
