What is theta entrainment?

Theta brainwaves (roughly 4–8 Hz) are associated with deep relaxation, meditation, and the drowsy, creative state just before sleep. Theta entrainment uses rhythmic audio cues — typically binaural beats — to gently nudge your brain toward that frequency band.

How Quiet Deep uses it

Quiet Deep generates adaptive theta entrainment audio that:

• Starts at a frequency matching your current state.
• Slowly tracks your brainwaves toward the theta band.
• Adapts in real time so the effect stays subtle and comfortable.

The thought-reduction score

Entrainment alone isn't a promise of calm — your mind still does the work. That's why every session ends with a quick thought-reduction score: a single number for how "quiet" your mind felt. Track it over weeks and you'll see whether the practice is actually compounding.

Quiet Deep is a wellness tool, not a medical device. It is not a treatment for any condition.
