## What is Naplab?

Naplab is the world’s first biometric feedback-based stimulation app that uses only your phone for biometrics — no wearables needed. It turns your iPhone into a personalised digital sleeping pill, using AI to estimate your sleep stage and adapt sound in real time so you fall asleep faster and stay asleep longer.

Naplab’s unique soundscapes with AI integration gently guide you into deeper, more stable sleep, helping you wake up more refreshed.

All biometric processing is done securely on your device, giving you a science-backed, privacy-first way to consistently improve your sleep quality.
