## What is ThirdTone?

The ThirdTone app offers an immersive sound therapy experience designed to promote healing and balance through the power of acoustic binaural tones. Developed by composer Evan Premo and sound therapist Lisa Mase', the app delivers carefully crafted frequencies that align with the body's natural rhythms, encouraging organ systems to restore equilibrium. 

By presenting slightly different frequencies to each ear, the app creates auditory illusions known as binaural beats, which can influence brainwave activity and synchronize neural oscillations with the resting frequencies of organs like the heart and stomach. This approach integrates modern scientific understanding with ancient healing traditions, drawing from principles in acoustics, neurobiology, and time-honored practices from cultures around the world. 

The ThirdTone app is designed to be accessible to all, aiming to support individuals seeking relief from chronic conditions, experiencing acute bodily sensations, or desiring a deeper connection with their embodiment. Users are encouraged to engage with the app's sound frequencies to align internal rhythms and restore both physiological and psychological equilibrium.

This is a high quality app and a fresh approach to binaural beats. Definitely recommend!

### 5/5 — Tones help beyond the suggested use

*2026-07-15*

I use these tones often and find them to be very helpful. Surprisingly I find that they work just as well over my phone or car speakers. They’re a miracle for my dog who’s afraid of fireworks and thunder. Find Safety seems to work for him every time.

### 5/5 — ThirdTone

*2026-07-13*

What makes ThirdTone stand out is that its sound formulas are informed by peer-reviewed research and clearly explained, so I can choose what to listen to based on the result I’m looking for or the state I’m in. The combination of sound-therapy expertise and classical musical training—using acoustic instruments to create binaural frequencies—gives the experience a depth and authenticity that feels truly unique.

### 5/5 — Amazing Results
