Woo Woo Woo: A binaural beats app

By alvin ~ Posted Tue, 01/20/2026 - 10:44

Woo Woo Woo — also known as just Woo Woo — is a simple, totally-private, binaural beats app for meditation, relaxation, focus, and sleep.

Because we use binaural beats every day, we took the time to create an app that works simply and privately, and has the features we want.

Note 1: This is a paid app because we have a lot of other ideas we’d like to implement over time, and we couldn’t afford to implement those ideas with a free app.

Note 2: The app Privacy Policy and Technical Support information is shown later on this page.

Features

These are the current features of our app:

  • Beat Frequency: Adjust from 0.5 to 40 Hz to target the brainwave states you want. (See the brainwave states listed below.)
  • Tone Frequency: Choose your carrier tone from 40 to 600 Hz. Lower tones tend to be more relaxing, and higher tones tend to be more energizing.
  • Presets: Easily save your favorite settings, so you can quickly recall those favorites for focus, meditation, and relaxation.
  • Background Playback: Plays in the background so you can also listen to your favorite music, podcasts, audiobooks, etc., if desired.
  • Switch ears: The base tone can be switched between the left ear and right ear as desired. We find this helpful when you realize you’re listening to tones, but don’t hear any beats. (We suspect that there is a certain “brain fatigue” in listening to beats, and this might be a way to overcome that.)
  • Auto-Stop: Optionally stop playback when headphones disconnect.
  • No ads, no subscriptions, no account required: Everything works locally on your phone, so the app is completely private.
  • Works on iPhone, iPad, and Mac, too: On iOS, we’ve written the app so it not only works on your iPhone, but also your iPad and Mac, so you can use it anytime, anywhere.

What are binaural beats?

With the app we generally assume that customers already know what binaural beats are, but in short:

When you hear two slightly different frequencies in each ear, your brain perceives a third tone — the “beat” — at the difference between them. Research suggests that the Hz of that beat can help guide your brain toward different mental states.

Brainwave States

Here’s a quick look at Hz ratings and their corresponding brainwave states:

  • Delta (0.5-4 Hz): Deep sleep
  • Theta (4-8 Hz): Meditation
  • Alpha (8-13 Hz): Relaxation
  • Beta (13-30 Hz): Focus
  • Gamma (30+ Hz): High cognitive function

Requirements

Stereo headphones or earbuds are required. Binaural beats do not work with speakers.

About the name

The name Woo Woo Woo is based both on the sound you hear when you play binaural beats, but also the sound one of our Siberian Huskies makes every day when she wakes around the office (which is usually “woo woo”, but occasionally “arooo...”).

Privacy policy/statement

With Woo Woo Woo, everything works locally on your phone, so the app is completely private. The only data we save is (a) your “preset” settings, and (b) your last-used settings (so they can be recalled the next time you start the app), and again, that data is only stored on your phone.
