Science-backed sound frequencies for anxiety, stress, sleep, and focus. No side effects.
* Headphones required for binaural effect
Delta sessions guide your brain into deep restorative sleep — the same frequencies naturally present in deep sleep stages.
Theta and alpha frequencies have the strongest research support for reducing state anxiety and measurable cortisol reduction.
Beta binaural beats support sustained attention and reduce mental wandering — used in neurofeedback research for concentration.
Alpha sessions quiet the default mode network — the brain region responsible for rumination, worry loops, and mental restlessness.
Theta is the frequency of deep meditation and creative insight. Used by practitioners for decades to accelerate depth of practice.
Gamma frequencies are associated with heightened perception and mental activation — ideal for high-output focused work.
Left ear hears one frequency, right ear hears another. Your brain detects the difference and entrains to it — this is the binaural beat.
Your brainwaves gradually synchronize with the beat — guiding you into delta, theta, alpha, or beta states depending on your session goal.
The base tone matters too. Tune it from grounding 432 Hz to healing-associated 528 Hz for a fully personalized experience.
Binaural beats require stereo separation. Any pair of earbuds or headphones works. No devices, no sensors, no hardware.
Sleep onset, burnout recovery, deep restoration
Anxiety relief, meditation, emotional processing
Stress relief, relaxed focus, mental fatigue
Concentration, ADHD support, cognitive clarity
Peak performance, energy, heightened awareness
Neural entrainment takes 7–10 minutes to establish. Here's what the research shows for each window:
Not enough for full entrainment but measurable relaxation begins. Good for acute stress before a meeting or presentation.
Entrainment begins establishing. You'll notice a distinct change in mental state — calmer, more focused. Good daily maintenance.
The clinical sweet spot. Cortisol measurably drops, full neural synchronization is established. Most studies use this window.
Delta sessions need extended exposure for full nervous system reset — burnout recovery, chronic insomnia, deep meditation states.
Based on peer-reviewed research on binaural beat entrainment and brainwave synchronization.
"I've tried every sleep app. KAIND® is the first one that actually puts me under within 20 minutes. The delta session is genuinely different."
"As someone with ADHD who doesn't want to be on medication forever — the beta focus sessions have become a real tool during work sprints."
"The aura visualization during a session is something else. I use the alpha flow session before creative work and it genuinely opens something up."
3-day free trial, then $9.99/mo or $79/yr. Cancel anytime. KAIND® is a wellness tool, not a medical device.
Put on your headphones. Set your intention. 20 minutes is the sweet spot — long enough for your brain to fully entrain to the frequency.
