Binaural beats are an auditory illusion created when two slightly different frequencies are played in each ear. Your brain perceives the difference as a rhythmic beat. For example, if 200Hz plays in your left ear and 210Hz in your right, your brain hears a 10Hz beat. Research suggests this can influence brainwave patterns through a process called Frequency-Following Response (FFR).

Yes, stereo headphones are required for the binaural effect. The left-right frequency difference is the mechanism that makes binaural beats work. Mono speakers or single-ear headphones won't create the effect. For noise and natural sounds, speakers work but the neural tone layer will be less effective.

No. AURA is a wellness and lifestyle application, not a medical device. It is not intended to diagnose, treat, cure, or prevent any disease or medical condition, including insomnia, ADHD, anxiety, or tinnitus. If you have a medical condition, consult a healthcare professional before use.

No. Do not use AURA while driving or operating machinery. Binaural beats can cause drowsiness and disorientation, especially with Sleep and Calm presets. Safety first — only use AURA when you can safely relax or focus without needing to react to your environment.

For ADHD focus, we recommend: Deep Focus (15Hz Beta), ADHD Work Mode (Café + Beta combination), or White Noise (with embedded Beta). Start with 25-50 minute sessions. Use headphones for the binaural effect. The external rhythm provides "scaffolding" for attention. Combine with the café ambience if you work better with social energy around you.

AURA includes Blue and Violet noise colors specifically designed for high-frequency tinnitus masking. These emphasize the frequency range where many tinnitus sufferers experience phantom sounds (8-16kHz). While not a treatment, they may provide auditory masking comfort. Start at low volume and adjust to comfort.

No. AURA is built privacy-first. All session data, preferences, and usage patterns stay on your device. We do not track your listening habits, sell your data, or use third-party analytics SDKs. We don't even require an account. Deleting the app removes all data permanently.

Go to the Combinations tab. Tap "Create New" and select up to 3 layers: a Neural Tone (binaural beats), a Noise Color, and/or an Environment (Natural or Human Space). Adjust each layer's volume independently. Save your combination with a custom name. You can create unlimited combinations.

AURA supports background audio playback. If sound stops when you lock your screen, check: 1) iOS Settings > AURA > Background App Refresh is ON, 2) Control Center shows the audio player is active, 3) You haven't enabled Low Power Mode (which restricts background audio). If issues persist, restart the app or contact support.

Apple Watch integration is planned for a future update. You'll be able to start/stop sessions, adjust volume, and view basic controls from your wrist. HRV (heart rate variability) adaptive audio is also in development — the app will adjust frequencies based on your physiological state.
