Biosignal Data Collection & Analysis

The WillSleep app analyzes your sleep quality and patterns each night using biosignal data collected from your smartwatch.

Personalized Recipe

Algorithm

Based on your previous night’s sleep data

the algorithm generates the most suitable

recipe for your current condition— guiding

you toward a healthy, long-term sleep

rhythm rather than short-term relief.


ASMR and White Noise

ASMR music with binaural beats* promotes brainwave synchronization*, helping improve sleep quality and support REM sleep.

Enhance FLN

GNN-Explainer analysis shows that vagus

nerve stimulation modulates the fronto-

limbic network*, supporting improved

emotional regulation and sleep quality.


Enhanced Brain Connectivity

Clinical trials show that 7 weeks of WillSleep® use

improves sleep quality and reshapes brain networks linked to stress regulation.

* Binaural Beats: A brainwave entrainment technique where different frequencies are played to each ear, allowing the brain to perceive their difference as a rhythmic resonance.

* Brainwave Entrainment: A natural process in which brainwaves synchronize with external rhythmic stimuli such as sound, music, light, or tactile signals.

* Fronto-limbic Network (FLN): A neural network connecting the frontal lobe with limbic regions such as the amygdala and hippocampus, playing a key role in emotion regulation, cognition, and decision-making.
