Binaural Beats: Aura

Binaural beats for focus, sleep, and meditation. Binaural Beats: Aura plays binaural frequencies as one pure tone in each ear. The difference between those tones is the binaural beat. Headphones are required. On a speaker the tones mix in the air, so the beat does not form.

Binaural beat frequencies

Focus, 40 Hz gamma. 220 Hz in the left ear, 260 Hz in the right. A steady frequency tone for work that needs to stay with you.

Sleep, 2 Hz delta. 174 Hz left, 176 Hz right. A slow binaural frequency for rest.

Meditation, 7 Hz theta. 432 Hz left, 439 Hz right. A quiet beat for sitting.

Recovery, 10 Hz alpha. 136 Hz left, 146 Hz right. A calm, alert pause after effort.

The only sound in a session is a pair of pure frequency tones. Aura does not play music, white noise, or nature sounds.

The app reads the current audio output and shows the device name your phone already reports: wired, Bluetooth, USB, or a hearing aid. If headphones disconnect, the session pauses. A channel test plays a tone on the left or the right so you can confirm each ear hears its own frequency. You can choose to keep listening on the speaker.

Playback continues with the screen off. The notification shows the session and lets you pause or stop. A mindfulness streak stays on the phone and counts the days you listen. There is no account. What you play is not uploaded.

The app is free. A free session lasts 30 minutes. Watch three short ads to earn one session. All four presets are included. Where the law asks, you choose how ads are personalized.

Lifetime Premium is one payment through Google Play, not a subscription. It removes ads, allows any length up to 24 hours, and lets you set your own binaural frequencies. The carrier runs from 100 Hz to 800 Hz. The beat runs from 0.5 Hz to 40 Hz, in steps of 0.5 Hz. The left ear plays the carrier. The right ear plays that tone plus the beat.

Aura is a listening app for binaural beats. It does not diagnose, treat, or replace medical care. The frequencies above are the tones the app plays, not a prescription.
