The Problem
This is not a willpower problem. Modern work was designed to take movement out of the system.
Screens replaced places. Meetings replaced walking. The body was left out of the job.
We call this the Static Workday.
The one in your chest pumps blood out to the body. The one in your calves sends it back up to the heart, against gravity. Your calf muscles contract with every step, and medical literature calls this pump the body’s second heart.
The moment you sit down, that contraction stops. The pump goes quiet, and it stays quiet for as long as you sit in front of a screen.
This is the Second Heart Shutdown.
You do not notice it as pain. Your legs feel heavier at the end of the day, your shoes fit a little tighter.
Advice collapses when it meets a system that rewards stillness. The meeting does not end. The flight continues. The device on your wrist buzzes, and you swipe it away.
None of them replaces what the body loses when it sits down.
A New Category
ARCH is a wearable walking simulator. Worn below the knee, it mechanically reproduces the movement of walking while you stay seated.
It does not apply compression and it does not pass current. All it does is reproduce the movement of walking, mechanically.
You put it on. You sit down. You work.
One full cycle every second. Four micro linear actuators below the knee work in sequence, and each sequence mechanically reproduces the contraction and release that calf muscles perform while walking.
The operating cycle of the device, up to sixty per minute. Patent no. TR 2024/012587.
Used in a seated position. When you stand up, the motion sensor stops the device.
Five sizes, fitting calves from 31 cm to 55 cm. Worn below the knee, fastened with one hand.
Graphite Black
Designed for indoor use. Not for showering, swimming, or sports. It does not run continuously; it engages when needed and waits when it does not. If you want, a second device pairs with the first so both legs work together.
Three sensors read pulse, tissue oxygenation, and fluid balance. The device uses these readings to set its own operating timing.
It shows the readings in the app; it does not offer a health assessment or interpretation. Machine learning runs on the device itself, so the longer you use it, the better it matches your rhythm.
Your sensor data stays on the device and your phone. It is not sent to a server.
Bioimpedance measurement uses a very low-level signal. It is not recommended for people with a pacemaker or similar implant.
Eight-hour focus blocks you cannot interrupt.
Hours where standing up is not an option.
Chains of calls that do not end.
Cars, trains, waiting areas.

The universal daily goal, and the same number ARCH delivers on a single charge. Without you leaving your desk.
Figures reflect the intermittent use pattern ARCH is designed for. Continuous operation shortens run time.
"How can we preserve an ancient biological system in a modern sedentary world?"
Human bodies weren’t made for stillness. For thousands of years, we moved to survive. But the last few decades introduced something evolution didn’t prepare us for: sitting.
Our circulatory system wasn’t built for this new lifestyle. Gravity works against us when we’re seated, and our natural "second heart", the calf muscle pump, stays dormant.
We bring together experts from health sciences, biomedical engineering, and industrial design to deliver a device that tracks your body and actively supports it during inactivity.

No. It does not stimulate muscles with electrical current. Four micro actuators below the knee produce a mechanical pressure cycle.
No. Compression applies static pressure, while ARCH produces a cyclic mechanical movement. It does not replace treatment prescribed by your doctor.
No. ARCH V1 is a consumer wellness product. It is not intended to diagnose, treat, or cure any condition.
Yes, that is exactly what it was designed for. It does not run continuously; it engages when needed and waits when it does not.
10,000 steps equivalent, and up to 12 hours on the leg. Continuous operation shortens run time.
No. You can start a session with the button on the device, without the app.
Your sensor data stays on the device and your phone. It is not sent to ARCH servers.
First shipment target is the end of October 2026. Reservations ship in order.
