PhaseHarbor is an offline sound generator and meditation timer for binaural beats, isochronic pulses, ambient noise, and custom listening routines with no subscriptions, no ads, and zero tracking.

Use it for meditation, quiet background sound while working or studying, wind-down routines, or building your own frequency mixes. All audio is synthesized live on your phone at 48 kHz in real time, so there are no loop seams or sudden jumps.

WHAT'S INCLUDED
• 40 Built-In Presets: 16 pure tone presets, 6 noise and nature soundscapes, and 18 multi-stage routines and timers.
• 4 Tone Styles: Binaural beats (headphones required), monaural beats, isochronic pulses, and stereo alternating tones across Delta, Theta, Alpha, Beta, and Gamma frequency bands.
• Noise & Nature Layers: White, pink, and brown noise, plus procedural gentle rain, forest wind, and ocean waves.
• Custom Session Composer: Build multi-segment routines with custom frequencies, gradual ramps, ambient layers, and an optional soft completion gong. Export or share presets via JSON or QR code.

TRANSPARENT & COMFORTABLE
• Clear Parameters & Evidence Notes: Every preset shows its exact frequencies and levels, paired with offline Evidence Cards (Acoustics Established, Outcome Evidence Mixed, Experimental)—no hype or hidden labels.
• Built-In Audio Safety: Smooth fade-in/out curves, an always-on -1.0 dBFS digital ceiling, and automatic pause if headphones disconnect.

PRIVATE BY DESIGN
• 100% Offline: Requests no Android INTERNET permission.
• Zero Tracking: No accounts, ads, analytics, or listening history.
• Yours to Control: Presets and settings stay on your device, with one-tap local data deletion in Settings.
