One for Day. One for Night.
Cirdia is a two-device wearable system because your day and your sleep have different needs.
The Day Device is built for movement and real life. The Night Device is built for comfort and recovery.
Together, you get continuous insight without forcing one form factor to do everything.
- The Day Device tracks movement, exertion, and daily rhythm—designed to look like a wearable you actually want to wear.
- The Night Device is light and screen-free for sleep—optimized for consistent overnight recovery signals.
- One simple swap keeps data continuous—no charging gaps, no wearing a bulky device to bed.
Both connect to one app, and a single stand keeps your routine simple: wear one, charge one.
