LYEONS Heart Release
Introducing LYEONS Heart. We want to learn from your experience at each step, so we are starting small, listening closely and sharing what we learn. Our aim is to keep quality, transparency and care at the centre.
On this page you can learn more about each stage, see how the first devices are made, and register your interest.
Beta Launch (Closed)
A small community release. You receive an early unit, hand assembled with care by in house engineering team, and simple ways to tell us what helps in daily life.
Pre-Production Launch
A pre-production batch that helps us set up the production line and polish finishing for wider availability.
Full Release
Wider availability with refined finishing and the same focus on safety, credibility and compassion. You can follow progress and be notified when orders open.
How Initial Devices Are Made
Whilst LYEONS Heart is being produced, we will keep you updated with photo notes from the studio so you can see how the units are coming together at each step.
Hand-built by our founding team
Assembled one by one by an electronic engineer, a design engineer, a mechatronic engineer, and a biomedical scientist from Imperial College London. Each unit is put together with care and attention.
3D-printed housing
Our current housings are made using in-house 3D printing, so early units may have a few natural surface variations. As we move towards mass production, your feedback helps us refine every detail, and we will support you closely throughout the beta period.
Personalised
While 3D-printed parts aren’t as smooth as mass-produced versions, they allow us to offer calming, nature-inspired colours: Pebble, Bark, Olive, and Blueberry— chosen to bring comfort and personal.
Tested & signed off
Every device is reviewed before it leaves our studio. But if you ever run into an issue, we will be right here to work with you to make sure you’re happy with your LYEONS Heart.
Hand-crafted packaging & follow-up
Carefully packaged and gift-ready for you or a loved one. As an early user, we would love to shape our support together with you. Your thoughts and experiences will help us learn, improve, and grow the journey ahead.
“Using the device has helped me stay calmer in situations that would normally trigger anxiety or sensory overload.”
In Q4 2025, we beta launched LYEONS Heart with our first group of early users.
79% of users found LYEONS Heart clearly helpful, and 100% found it at least somewhat helpful. Many described it as supportive during moments of stress, helpful before sleep, and reassuring to carry throughout the day, with regular use across real-life situations such as overwhelm, travel and winding down at night.We are now using what people shared to guide the next stage as we prepare LYEONS Heart for pre-production.
Pre-Production Launch
Pre-Production Launch is our next step after the Beta Launch. This batch release will support us in setting up the semi production line and refining the transition from current units to wider availability. The pre-production batch has now been launched. This will be the final small-scale release before full availability.
Full Release
The Full Release marks our shift from small-batch builds to mass production. This stage will bring a more consistent and refined housing, though initial colour options will be more limited than the 3D-printed versions as we establish tooling. To ensure we release the most preferred colours, you can provide your colour preference when you join the interest group. 🙂
Sign-up is open now, with no payment required — it simply registers your interest. Devices are planned for release in Q4 2026, when wider availability begins.
