It’s been an exciting season of progress here at Cirdia, both in the lab and on the wrist.
If you’ve seen my short update video, you know that we’ve moved from early design renders to real, wearable prototypes for our Day Device, Night Device, and charging stand. These models are now in wear testing, helping us understand comfort, materials, and real-world usability before we finalize hardware and assemble the fully functional devices.
Hardware Progress
Our Day Device is built to feel like an everyday accessory - lightweight, elegant, and designed to fit comfortably on a woman’s wrist.
Our Night Device is soft, low-profile, and secured with a breathable fabric band that doesn’t catch on sheets - because most of us take our jewelry off at night, not sleep in it.
This week, we finalized and are sending out the circuit board (PCB) orders. These boards are the core electronics that bring the sensors and system logic to life. Once we receive them, our engineering focus will be on testing and validating that all components perform exactly as expected.
Only after those boards are confirmed will we move to order our first fully functional prototypes - the complete, working versions of the devices.
While that manufacturing process runs its course, our team will be expanding the firmware, the software that runs on each device, to prepare for seamless integration between the hardware and the Cirdia app.
The App: Private by Design
Alongside the hardware, our Cirdia mobile app is now installable on both iOS and Android.
It connects to our prototype devices via Bluetooth and captures sensor data such as steps, movement patterns, heart rate, temperature, and sleep trends - and it is processed locally on your phone.
What does that mean? Well, it means your biometric data is not stored on our centralized servers, and because we never have it, we can easily promise that it’s never shared or sold. That’s our principle of privacy by architecture - not just privacy by policy.
Provisional Patent Filed: Privacy and Adaptive Wellness Architecture
We recently filed a provisional patent application covering Cirdia’s privacy-first architecture and adaptive wellness system for midlife and beyond.
This filing formalizes how our software interprets data directly on the device, combining transparency, personalization, and privacy to generate insights that stay under your control. It also outlines how our Wellness Modes adapt to each user’s goals and context over time.
Introducing Cirdia’s Wellness Modes
At the heart of Cirdia are three Wellness Modes - the foundation for how the system supports different dimensions of wellness across the seasons of your life.
Activate - For building capability and energy.
Helps you strengthen your baseline: movement, stamina, recovery, and confidence in daily life.
Sustain - For stability and rhythm.
Supports consistency and balance - the patterns that keep you feeling well, rested, and independent over time.
Transform - For focused, intentional change.
Designed for short seasons when you want to reset, build new habits, or reach a goal, with progress tracking that’s motivating but never intrusive.
Together, these modes form a flexible framework that keeps Cirdia personal. You’re not locked into one path; you can shift between modes as your priorities evolve. It’s wellness on your terms, grounded in your patterns and powered by privacy.
Looking Ahead
In the weeks ahead, we’ll be testing the new PCBs, validating the electronics, and expanding our firmware in parallel. Once everything checks out, we’ll move to produce our first fully functional prototypes that combine all the elements - hardware, firmware, and the app into one integrated system.
And in January, we’ll open 100 spots only for our Founding Member campaign. This offer is for a small group of women who are excited for Cirdia to come to life and who will follow along closely as we transition from engineering validation to production readiness.
It’s been a steady and thoughtful build - one that reflects how we want the product itself to feel: reliable, respectful, and designed to last.
