Clicking Effect in Speakers

The app seems to produce a “clicking” effect when run through a good set of powered speakers. The clicking effect stops when run at the same time as another app that is simultaneously playing music.

Useful, besides random pausing

The tone will pause randomly when I receive a notification. Besides that, I enjoy the app and the UI

FAQ

What is an isochronic tone?

Isochronic tones are regular beats of a single tone used for brainwave entrainment. Unlike monaural beats, they consist of separate pulses of a single tone, creating a stronger stimulus for brain entrainment.

What can I do with the Isochronic Tone Generator app?

You can create custom isochronic tones with variable carrier frequencies, mix them with your own music, set a timer for sessions up to 59 minutes, and use presets for sleep, relaxation, or meditation. You can also save your favorite tones.

Is this app free to use?

Yes, the Isochronic Tone Generator app is free to use. It does not contain in-app purchases or advertisements.

Do I need headphones to use this app?

No, headphones are not required for entrainment to be effective with isochronic tones. The interference pattern that produces the beat is outside the brain.

Who should not use this app?

Individuals with epilepsy should not use mind entrainment products without the approval of a medical physician. It is also advised not to drive or operate dangerous machinery while listening, as the technology can induce hyper-relaxed states.
