Introducing
The Day & Night Duo

Two devices. One seamless wellness experience.

One for Day. One for Night.

The Cirdia wearable system includes a stylish Day Device and a soft, comfortable Night Device — designed to give you full-spectrum insights while staying out of your way.

  • The Day Device supports your movement, activity, and daily rhythms — all without screaming "fitness tech."
  • The Night Device is lightweight, discreet, and optimized for uninterrupted rest and recovery data.

Both connect to a single app, and share a minimalist stand that keeps your routine simple and your devices charged.
