About this app

Bía trains your brain to sleep better every night.

Powered by neurofeedback, neural soundscapes, sunrise wakeups, and advanced real-time sensors, Bía helps you fall asleep faster, stay asleep longer, and wake up clear, sharp, and ready to lead.

Bía captures brain activity live right in the brain where sleep happens. From there, it creates a closed-loop system that responds to your brain in real time with subtle audio cues that support deep, restorative rest.

The Bía app gives you personalized sleep coaching and insights across sleep quality, strain, stress, recovery, and brain health. It adapts nightly based on your physiology and lifestyle, guiding you with practical steps - when to wind down, when to push, and when to rest.

Note: The Bía app requires a Bía Smart Sleep Mask.
