On Our Wrists: How the Day Device Is Taking Shape

We’ve been deep in the work—prototyping, adjusting, refining. And now we’re in one of the most satisfying parts of the process: the Cirdia day device is finally on wrists.

In this new video, we walk through the full evolution:

  • Digital design and mechanical planning
  • Final renderings of the aluminum casing and band
  • Our first physical prototype on wrist and seated in the charging stand



This is the version now going into comfort and wearability testing—and it already feels like a milestone. The band, the weight, the wrist feel: this is the stage where we start learning from real-world use.

The night device is following right behind. We expect to have a similar video showing its physical casing and band within the next two weeks. That version will also begin wearability testing, while circuit integration and full app syncing are still underway. We're aiming to have the fully functional version of the night device ready for testing approximately six weeks later.

We’re currently working on the battery consumption analysis and miniaturization work for that board, threading the needle between function and form in our extra-small casing. It’s a demanding process—but worth it.

In parallel, our privacy-first app architecture is holding steady: no cloud upload, no data harvesting, no ad trackers—just wellness support that runs locally and respects your autonomy.

This phase is exactly what we hoped it would be: focused, deliberate, and guided by real-world feedback.

Here’s what to expect next:

  • New video of the night device in physical form (coming soon)
  • On-wrist comfort and wear testing with community members
  • And potential early gift options ahead of the holidays
  • Our presale community opening once full system prototypes are in test mode

We’re not in a rush. We’re in rhythm.

Thanks for walking this with us.
