FreqCraft - Isochronic Tones

FreqCraft is a precision binaural beats and isochronic tones generator for brainwave entrainment — built to run clean and uninterrupted.

Plays alongside your other audio. FreqCraft does not seize audio focus, so it layers under music, podcasts, and video without pausing them. During a phone call — incoming or outgoing — the session pauses on its own and resumes automatically when the call ends. Nothing to stop or restart.

It is a one-time purchase, not a subscription. What you buy is the whole app, and it stays yours.

It has no internet permission. That means it physically cannot phone home, send your activity anywhere, or track you — not a privacy promise, a property of the build. Everything runs offline, on your device.

A modern successor to Brainwave Generator (BWGen), the long-abandoned Windows desktop tool — now built natively for Android.

WHAT MAKES IT DIFFERENT
- Every Hz is visible and editable. Set any carrier and beat frequency, down to the decimal. No hidden processing, no black box.
- Four real waveforms — sine, square, triangle, sawtooth. A true frequency and tone generator, not a preset player.
- Binaural and isochronic modes. Isochronic needs no headphones.
- Transducer-ready. Clean low-frequency output drives tactile transducers and bass shakers — physical vibration you feel, not just sound.
- Fade in/out, session timer, and a readout that always matches what the engine plays.
- Sourced presets — every factory preset cites its reference, in the app.

FOR THE TRUE BINAURAL EFFECT
Binaural mode needs wired stereo headphones and true stereo output. If a track sounds like a pulsing "wah-wah," or you hear the beat through a single earbud, your phone is collapsing to Mono — turn off Mono audio in Accessibility, and switch off any system EQ, surround sound, or "audio enhancement." A binaural track should sound like one smooth, steady tone.

It guides you with advisories; it never locks you out. You stay in control of the signal.

Private by design: no tracking, no telemetry, no internet permission. Just precise frequencies, on your device.
