Listing changes AppTracker has observed for this app in this storefront — new versions, price moves, rating shifts, and store copy.
NEW: - Choose which ear hears the higher tone. Change it mid-session and the two tones glide across in about a second -- no stopping, no restarting. Most binaural apps fix which ear gets which; Byna lets you decide. IMPROVED: - Pressing Stop now fades the sound out over five seconds instead of ending abruptly, and the controls answer the moment you press. Headphones required for binaural beats to work.

About
Fall asleep faster. Focus deeper. Meditate without the noise. Byna plays two slightly different tones -- one in each ear -- and your brain hears a third: a slow pulse at the difference between them. It's called binaural beats, and it's been studied since the 1970s. Research suggests the brain tends to fall in step with that pulse, which is what each preset is tuned around. Completely free. No ads. No accounts. No data collection. Ever. -- 7 PRECISION-TUNED PRESETS -- Each preset is tuned to a specific brainwave band: - Wind Down (Delta, 2 Hz) -- Ease into deep sleep - Quick Recharge (Delta, 3 Hz) -- A restorative pause - Inner Calm (Theta, 4 Hz) -- The threshold before sleep - Open Mind (Theta, 5 Hz) -- Explore quiet awareness - Still Mind (Theta, 6 Hz) -- Settle into meditation - Quiet Focus (Alpha, 10 Hz) -- Calm, clear concentration - Deep Work (Beta, 18 Hz) -- Sustained mental focus -- REAL-TIME AUDIO SYNTHESIS -- Byna generates pure tones in real time -- no pre-recorded loops, no compressed audio files. Each session creates fresh sine waves at precise frequencies, so what you hear is mathematically exact. Carrier frequencies are held in the 200-500 Hz range where binaural perception is strongest. -- VISUAL ANIMATIONS -- 4 animation modes -- Pulse, Morph, Glow, and Ripple -- sync to your session's beat frequency. Watch the visuals breathe at the same rhythm, or close your eyes and just listen. -- PINK & BROWN NOISE -- Layer soft pink or brown noise under your binaural tones to mask distracting sounds. Helpful in noisy environments or when the pure tones feel too exposed on their own. -- THOUGHTFUL DESIGN -- - Sessions start with a gentle fade-in and gradual frequency progression - Volume starts at 70% -- move it up or down whenever you like - Sleep presets skip the closing frequency wind-down -- the sound just fades away - Works completely offline -- no internet needed - Keep Screen On option for uninterrupted visual sessions - Auto-fullscreen mode for immersive listening -- WHY FREE? -- Most binaural beats apps charge $10-15/month for what is, at its core, two sine waves. The science is public domain. The math is simple. Byna exists to prove that a good binaural beats experience doesn't need a paywall. No premium tier. No "unlock for $9.99/month." Just headphones and a calm mind. -- HEADPHONES REQUIRED -- Binaural beats only work with headphones or earbuds. Each ear needs to hear a different frequency for the effect to occur. Any wired or wireless headphones will work. Built with care. Free forever.
