We built ThirdTone because we believe the body already knows how to heal. Evan brings decades of deep listening to sound. Lisa brings a lifetime of studying the body. Together, we've created something neither of us could have made alone: acoustic protocols that meet you where you are and guide your whole being toward balance.

Six sonic elements to activate
healing states
Every frequency comes from acoustic instruments, digitally shaped to influence brainwave states. The full library lives inside the app.
Wellness Formulas and Custom Protocols move with you on the healing path.
Real effects, observed across neuroscience
and psychoacoustic research.
Binaural beat exposure has been shown to significantly predict post-session relaxation outcomes, accounting for meaningful variance in individual responses.
McConnell et al., 2014 → 22+ Clinical studies analyzedA meta-analysis of 22 peer-reviewed studies found statistically significant effects on anxiety, cognition, and pain perception.
Garcia-Argibay et al., 2019 → Measurable Creative cognition shiftsFrequency-based audio stimulation has been shown to influence divergent thinking—one of the core markers of creativity—with effects varying by individual neurobiology.
Reedijk et al., 2013 → Whole-brain Neural engagementResearch shows that binaural and frequency-based auditory stimulation can modulate activity across multiple regions of the brain, supporting integrated neural processing.
