REAL-TIME SYNTHESIS ENGINE

Pure Frequencies.
Mathematically Perfect.

Unlike other apps that rely on compressed audio files or pre-recorded loops, Heal Tone generates every frequency in real-time directly on your device.

Completely Accurate Tones

Zero compression artifacts. Just pure, unadulterated sound waves.

No Fake Frequencies

We don't fake it. Our engine synthesizes the exact Hz required for your healing session.

Instant Calm

Reclaim your peace. Scientifically structured soundscapes to reduce anxiety and restore emotional balance on demand.

Nervous System Reset

Activate your vagus nerve with specific low-frequency tones. Designed to immediately counter the physical symptoms of stress and anxiety.

Sonic Sanctuary

Create a personal space of safety wherever you are. Whether you're commuting or overwhelmed at the office, our generative audio creates a protective barrier against chaos.

Nature Enhanced

We blend organic biomimicry with pure sine waves. This 'augmented nature' approach taps into your primal response to the natural world while delivering precise therapeutic frequencies.

Engineered for Rest

Heal Tone's algorithmic soundscapes adapt to your circadian rhythm, guiding you through every stage of the sleep cycle.

Phase 1

Prepare

Shift your nervous system from 'fight or flight' to 'rest and digest'. Our initial sequences use Alpha waves to gently lower cortisol and slow your heart rate.

Phase 2

Transition

Bridge the gap between wakefulness and rest. Theta frequencies mimic the brain's natural pre-sleep state, reducing sleep latency and quieting internal dialogue.

Phase 3

Deepen

Enter the restorative Delta state faster. Continuous, non-looping soundscapes mask environmental noise while entraining your brain for prolonged deep sleep.

Phase 4
zZ

Maintain

Stay asleep longer. Our dynamic synthesis adjusts subtly throughout the night to prevent micro-awakenings, ensuring you wake up feeling fully recharged.

People living with stress & anxiety confirm that Heal Tone has improved their quality of life

My Productivity Secret Weapon

I juggle multiple projects as a creative director, and 'deep work' was a struggle. Heal Tone's focus frequencies lock me in like nothing else. It's not just background noise; it's a mental state switch. 40Hz Gamma waves are now part of my daily toolkit.

Finally, Restorative Sleep

I've tried melatonin, meditation apps, white noise... nothing stuck. Heal Tone's sleep sequences are different. They don't just mask noise; they guide my brain down. I'm tracking better deep sleep numbers on my Oura ring since day one.

Quiet in the Chaos

My ADHD brain usually feels like a browser with 100 tabs open. The 'Grounding' soundscape is the only thing that helps me close them. It’s intuitive, effective, and beautifully designed. A must-have for anyone with a noisy mind. I use it during my commute and it completely changes the tone of my day.

Science that Works

I was skeptical about 'healing frequencies' until I looked into the data. Heal Tone bridges the gap between ancient practice and modern neuroscience. I feel physically calmer after a 20-minute 528Hz session.

Beautifully Simple

No clutter, no complicated settings. Just pure, effective sound. I love that it generates the audio in real-time rather than playing loops. You can feel the difference in quality compared to Spotify playlists.
