Not a gadget. It is an Agent first wearable. It learns your rhythm and hormonal shifts, then responds with a new kind of interaction that feels calm, personal, and useful. Steadier nights. Lighter mornings. Long term ease.
Made to live with you, not just measure you. Vilo follows the rhythms beneath your days and turns them into something you can understand, feel, and use.

shape what this new kind of interaction becomes.
Slim, light, easy to forget. No new rituals. It stays close, reads quietly, and shows up only when it helps.
Vilo senses in the background, night and day, learning your baseline. Steady, never noisy.
Beyond stages and HRV, Signal OS learns the shape of your nights. Wake gently, to a haptic alarm, no startle.

Advanced optical, temperature, and motion sensors read you cleanly. The hardware catches the signal. The AI makes sense of it.
Signal OS leaves numbers and charts behind, drawing sleep, mood, recovery, and cycle into patterns you can actually read.
