Shape your mindset with customizable Brainwave Entrainment Stacks. Listen in Binaural, Monaural, Isochronic, or combined Binaural + Isochronic Tone Modes.

Start with 100+ included Explore Stacks, or create your own by combining any of 300+ Multi-Stage Brainwave Entrainment programs with Guided Breathing and background audio elements into an integrated Stack. NeuralStack.io is designed for people who want more than fixed audio tracks. Instead of locking you into pre-made sessions and pre-mixed tones, NeuralStack.io provides advanced tone modulation and flexible tools to create custom soundscapes, so you can shape your ideal mindset for any situation. Includes 300+ advanced brainwave entrainment programs for focus, relaxation, stress relief, memory, insomnia relief, sleep, meditation, anxiety relief, and much more. Create custom multi-stage brainwave entrainment programs for your Stacks: * Add or remove stages, fine-tune stage durations. * Specify any beat frequency from 0.5–100 Hz. * Specify fractional frequencies with 2-decimal precision. * Choose carrier frequencies from 100–1000 Hz with automatic power equalization. * Listen in 4 Tone Modes: Binaural, Monaural, Isochronic, or phase-synchronized Binaural + Isochronic modes. * Supports Schumann Resonance frequencies (ex 7.83 Hz). Listen alongside other audio/video apps: * Set your preference to allow other apps at the app-level or the stack-level. Listen Offline: * Audio resources are synchronized to the device instead of being streamed, eliminating network traffic, saving battery life, and allowing you to listen offline. Guided Breathing: * Remix the included breathing programs to match your pace. * Create custom multi-stage breathing programs with adjustable tempo, text, and visuals. * Supports fractional breathing patterns, such as Coherent 5.5 second cycles. Advanced Global Settings * Use the app's Global Settings to modify tone characteristics, such as cycles-per-pulse and gain to sharpen or soften isochronic and monaural modulation. Stack Playlists * Organize your Stacks into playlists to support your daily routine. * Create sequences of Stacks that use different Tone Modes. Ambience and Nature * Layer dynamic ambience and nature sounds. * Remix programs, combining them to create multi-stage ambient and nature programs, and reuse them across different Stacks. Solfeggio and Schumann Frequencies * Includes single and multi-stage entrainment programs utilizing Solfeggio carrier frequencies and Schumann resonant beat frequencies to be remixed and customized. Color Noise * Layer a color noise element into your stack for sound masking and tinnitus relief. Pure Sine Waves * Create pure sine waves from 100 to 1000 Hz with power equalization and 2-decimal precision. * Remix and combine programs to create multi-stage Solfeggio progressions. Custom Audio Programs * Integrate personal audio files into your Stacks. * Note: This feature is only intended for personal audio files, such as those recorded with voice recording apps, and cannot access copy-protected audio or audio from streaming services.

Noxuma Sleep — smart alarm, snore log and simple night tracking. Listens to your night through the phone's microphone, shows you a detailed hypnogram in the morning, and wakes you with a gentle gradual sound. Noxuma works fully for free with your phone. Optionally connect Sleep Phaser lamps to explore sleep for more people in your household. The app also includes a growing library of practical, visual Sleep Tips. No account, no ads, works offline. Free. WHAT IT DOES • Sleep monitoring from microphone — movement, breathing patterns, snoring • Per-minute hypnogram: deep, light, REM, awake • Stats: sleep efficiency, time to fall asleep, time in each stage • Smart alarm with smooth 30-second fade-in — no jarring sounds • 12 built-in alarm sounds, or your own audio file PRIVACY-FIRST DESIGN Your nights stay on your phone. Sleep data and hypnograms are never uploaded, and there is no account or login. The microphone is analysed on the device in one-minute windows; raw audio is never recorded or sent. Short snore clips are saved only if you turn them on, and they stay on the phone too. To keep the app reliable, it sends anonymous technical diagnostics: crash and error reports, and a small launch ping with a random installation ID, the app version and the number of nights started. They never contain audio, sleep data or anything you typed. Anything else leaves your phone only when you choose to share it. WHO IT'S FOR For anyone who wants to know how they really sleep — without buying hardware, without monthly fees, and without compromising privacy. The app works fully offline and is free. NOTE Noxuma Sleep is a wellness app, not a medical device. The data is for personal insight only, not for diagnosis. If you have serious sleep concerns, please consult a doctor.
