I've tried dozens of meditation apps. SINE is the first one that SHOWS me sound healing works. Doesn't just claim it. The HRV data after each session is more convincing than any marketing.

The Problem
Most sound healing apps give you no proof.
No Proof It's Working
You listen to 30 minutes of sound healing and hope something is happening. No app shows you whether the frequencies are actually affecting your nervous system. You're meditating blind.
Compressed Frequencies, False Labels
Most '528 Hz' videos and playlists are MP3-compressed. What's on the label isn't what your brain receives. Real frequency work requires mathematical precision.
Either Beats OR Frequencies OR Sounds
One app for binaural beats. Another for solfeggio. Yet another for ambient sounds. None combines all elements of sound healing in one customizable system.

The 4 Pillars
Everything sound healing needs. In one app.
🧠
Binaural Beats
Two slightly different tones guide your brainwaves into specific states, from delta deep sleep to gamma peak performance. Real-time synthesis with 0.01 Hz precision.
Learn about Binaural Beats →🎵
Solfeggio Frequencies
From 174 Hz to 963 Hz. Centuries-old frequencies with modern research. 528 Hz reduces cortisol, 432 Hz lowers heart rate. Generated with mathematical precision.

Noise Therapy
White, pink, and brown noise with LFO modulation and cutoff filters. No loops, just infinite generation. Studies show: brown noise improves sleep quality and reduces tinnitus perception.

Ambient & Spatial Audio
46 hand-recorded nature sounds like rain, forest, ocean, and fire. All in 3D spatial audio. Every sound moves through space around you. Freely combine them with frequencies and beats.

The Research
Sound Healing Is Measurable
The science behind frequency-based sound healing is growing rapidly.
10–25% HRV
Frontiers in Psychology, 2024
Meditation over 15 minutes led to a 10-25% HRV increase. The longer the session, the stronger the parasympathetic shift.
Clinically Non-Inferior
JAMA Psychiatry, 2023
Landmark study: mindfulness meditation was clinically non-inferior to the antidepressant Lexapro for anxiety patients. Meditation as serious therapy.
8 Weeks
Harvard / Psychiatry Research, 2011
Just 8 weeks of meditation practice led to measurable changes in brain structure with increased gray matter in areas for learning, memory, and emotional regulation.

Use Cases
The Right Combination for Every Goal
😴
Sleep
Delta binaural beats (2 Hz) + brown noise + ocean ambient. Guide your brain into the deepest sleep phases and track the change in your heart rate.
🎯
Focus
Beta binaural beats (18 Hz) + pink noise + rain ambient. Block distractions and activate concentrated thinking for work and study.
🧘
Meditation
Theta binaural beats (6 Hz) + 528 Hz solfeggio + forest ambient. Reach meditative states that normally take years of practice, and measure it via HRV.
💆
Stress Relief
Alpha waves (10 Hz) + 432 Hz base frequency + nature night ambient. Activate your parasympathetic system in minutes and see the change in your HRV.
Experiences
What Practitioners Are Saying
As a therapist, I recommend SINE to my clients. The combination of binaural beats, solfeggio, and ambient in one app saves three separate subscriptions, and the bio data helps with treatment planning.

TherapistThe 3D spatial audio sounds are on a completely different level. When the rain moves around your head and the frequencies work in the background... that's immersive sound healing.

Frequently Asked Questions
What is sound healing?
Sound healing uses sound waves (frequencies, tones, and sounds) to promote physical and emotional wellbeing. This includes binaural beats (brainwave entrainment), solfeggio frequencies (specific healing frequencies), noise therapy (white, pink, brown noise), and nature sounds. SINE unites all four methods in one app.
Does frequency therapy actually work?
Research shows measurable effects: binaural beats can influence brainwaves (22-study review, 2019). 528 Hz reduces cortisol (Japan, 2017). 432 Hz lowers heart rate and blood pressure (double-blind study, 2019). And the 2023 JAMA study showed: meditation is clinically non-inferior to antidepressants. SINE lets you measure the effect on your body with bio-resonance.
What frequencies heal the body?
Different frequencies have different effects: 174 Hz for pain relief, 528 Hz for cortisol reduction, 432 Hz for heart coherence, delta waves (0.5-4 Hz) for regenerative sleep, theta waves (4-8 Hz) for deep meditation. The 'best' frequency is individual. That's why SINE tracks your body's response with bio-resonance.
How does sound therapy work?
Through three mechanisms: (1) Brainwave entrainment: binaural beats synchronize brainwaves with the target frequency. (2) Parasympathetic activation: certain frequencies and sounds activate the relaxation nervous system. (3) Neuroplasticity: regular practice changes brain structure (Harvard, 2011: measurable changes after 8 weeks).
