A free standalone app that builds you a complete binaural beats and brainwave entrainment session based on what you need right now, with real-time audio generation built in. No third-party tracks, no subscriptions, no accounts. Just open the app and press play.
Pick from eight scenarios covering focus, creativity, stress recovery, sleep, physical comfort, and more. The app recommends the right frequencies, durations, and practical guidance for each step, then generates the audio directly in your browser when you start the timer.
Binaural beats are generated using precision-tuned sine oscillators with 432 Hz harmonic carrier frequencies and a warm brown noise bed. Solfeggio tones use gentle amplitude modulation rather than harsh pulsing, so everything sounds smooth enough for extended sessions. Volume defaults to 30% and adjusts in real time.
Filter by daytime or evening routines, or build your own custom routine from scratch using any combination of frequencies and durations.
Install it on your phone for offline use: open frequencies.sophiesbureau.com, then tap Share and Add to Home Screen (iPhone) or tap the menu and Add to Home Screen (Android). It works without an internet connection once installed.
Built as a companion to my article "The 45 Minutes Before I Open My Laptop," which covers the published neuroscience behind brainwave entrainment, my personal morning routine, and the methodology behind the frequency sequencing.
What you get:
Eight scenario-based frequency routines with step-by-step guidance
Built-in audio generation for binaural beats (Schumann, alpha, theta, delta, beta, gamma) and Solfeggio tones (174, 285, 396, 417, 528, 639 Hz)
Real-time volume control with smooth fade in and fade out
Countdown timers with pause, resume, and skip controls that sync with the audio
Manual play/stop toggles for open-ended steps like ambient background listening
Animated brainwave visualisations for each frequency
Daytime and evening filter to match your schedule
Custom routine builder with full frequency library
Installable on your phone for offline use
Print button for a clean, branded routine card
Links to recommended audio sources and the companion research article
Headphones required for binaural beats. Solfeggio tones work through speakers.
