📖 How to Use
1

Choose a mode

"Binaural" lets you experience a beat sensation created by the frequency difference between left and right earphones. "Tone" plays the same frequencies as healing tuning forks as a simple steady tone. Earphones are recommended for both modes.

2

Choose a mood category

Tap one of the six categories — Sleep, Relax, Focus, Energy, Meditate, or Wake Up — to match your current mood or goal.

3

Set the timer and volume

Adjust the timer from 1 to 60 minutes and set your volume. The audio automatically fades out 4 seconds before the timer ends.

4

Press play to start

Press the play button to start the audio. To stop midway, press the button again.

Five Schools of Healing Tuning Forks

1. Medical Tuning Forks (C Octave Series)
The oldest system. Uses 64 / 128 / 256 / 512 / 1024 / 2048 / 4096Hz (all C octaves). Originally designed for neurological testing (vibration sense tests, fracture diagnosis), with 128Hz being the most commonly used. This app uses 256Hz, 512Hz, and 1024Hz.
2. BioSonics System (Dr. John Beaulieu)
A leading brand in modern sound healing tuning forks. Offers the "Body Tuners" C256Hz + G384Hz perfect fifth pair, the "Otto Tuners" weighted 128Hz + OM 136.1Hz, and the "Solar Harmonic Spectrum" — an 8-fork set based on Pythagorean tuning, among many other sets.
3. Planetary Frequency System (Hans Cousto / Acutonics)
A system that converts celestial orbital periods into the audible range through octave doubling. Includes Sun 126.22Hz / Moon 210.42Hz / Earth 136.10Hz / Mars 144.72Hz / Jupiter 183.58Hz, and more. Earth's annual orbit = 136.1Hz is the most widely adopted as the "OM tuning fork." This app's "Meditate" uses this frequency.
4. Crystal Tuner (4096Hz)
4096Hz is the base frequency of 8Hz raised by 9 octaves, and sits at the highest end of the C octave series. Used with quartz crystals for space clearing and meditation induction, it is one of the best-selling individual tuning forks.
5. Solfeggio System
A 6-fork set of 396 / 417 / 528 / 639 / 741 / 852Hz (expanded to 9 forks). Originating from 1970s numerology, it has weaker mathematical foundations compared to other systems, but 528Hz has been the subject of multiple studies. This app uses 528Hz for "Energy."

What Are Healing Tuning Forks & Crystal Tuners?

Healing tuning forks are metal forks that vibrate at specific frequencies (Hz), used as sound healing tools. Crystal tuners (4096Hz), OM tuning forks (136.1Hz), 528Hz tuning forks, and 432Hz tuning forks are used for different purposes. This app digitally recreates these tuning fork frequencies in your browser, so you can try them without owning a physical tuning fork.

What Are Binaural Beats?

Binaural beats are an auditory phenomenon where slightly different frequencies are played in each ear, causing the brain to perceive a beat. For example, playing 200Hz in the left ear and 210Hz in the right ear creates a 10Hz (alpha wave range) beat in the brain. This app supports five brainwave bands: delta (2Hz, sleep), theta (6Hz, meditation), alpha (10Hz, relaxation), beta (18Hz, focus), and gamma (40Hz, alertness).

Solfeggio Frequencies & Frequency Settings

Tone mode supports the following frequencies including solfeggio frequencies: 256Hz (medical tuning fork standard, sleep), 432Hz (relaxation, pilot RCT evidence), 512Hz (medical tuning fork, focus), 528Hz (solfeggio MI, energy), 136.1Hz (OM tuning fork, meditation), and 1024Hz (neurological examination tuning fork, wake up). Try different frequencies easily before buying a physical healing tuning fork.

How to Use

Choose a mode (binaural/tone), select a mood category (sleep, relax, focus, energy, meditate, wake up), set the timer and press play. Headphones are required for binaural mode and recommended for tone mode. No sign-up, no installation, no download needed — works entirely in your browser.
