No app to open. No breathing to remember. A wristband that catches stress building and calms it with a gentle vibration on your wrist, so you can stay in the moment.
Some people don’t register stress until it peaks. AcuSera is a wearable that catches it early and responds on its own, with vibration therapy at the P6 acupoint in a slow wave you breathe along with.
If stress sets things off for you, timing matters. AcuSera is a wearable that detects stress as it builds and responds with vibration therapy at the P6 acupoint in a slow wave you breathe along with.

You won’t have to keep checking in with yourself. Your body feels stress long before you notice it. Most of us only realize how stressed we were once it’s over. Sensors on both sides of your wrist track your heart, your skin and how you move, around the clock. Our algorithms turn those readings into a moment-by-moment picture of your stress.
So you won’t get buzzed for climbing them. AcuSera measures electrodermal activity (EDA): tiny changes in your skin’s sweat response, driven directly by your stress response. Most wearables don’t track it. Paired with your heart rhythm and movement, it tells real stress apart from a flight of stairs.
You won’t have to stop, find a quiet room or remember how to breathe. When stress builds, AcuSera starts vibration therapy, barely there at first and building gently so it never startles you, at the P6 acupoint on your inner wrist. The same vibration guides your breathing: it swells for four seconds as you breathe in and fades for seven as you breathe out. No screen, nothing to tap, no practice needed. You can keep doing what you were doing.
What you’re looking at is our working prototype, built to prove every part works together on the wrist. The AcuSera you’ll wear does everything V3 does in a smaller, lighter, more refined design, made to look good every day.
The hardest part of calming down is noticing you need to. Your watch tells you later, in a graph. AcuSera notices for you and starts vibration therapy on your wrist, right then. It doesn’t ask you to do anything. No app, no quiet room, no time set aside. You just get the moment back.
Compared with the typical features of popular smartwatches and fitness rings. Individual products vary.
Mindfulness shouldn’t need a quiet room and twenty spare minutes. AcuSera is made for the days you get neither.
When you’re caring for someone, your own stress is the last thing you notice. AcuSera notices it for you, while it’s still small, and responds before you’re running on empty, so there’s still some of you left at the end of the day.
No time or space to open a meditation app between calls. AcuSera responds right on your wrist when stress builds. No screen, nothing to tap, and nobody else notices. You stay ready for the next call, and bring less of the shift home.
The presentation, the exam, the game. Follow the wave on your wrist: breathe in as it swells for four seconds, out as it fades for seven. A long, slow exhale while you wait your turn, so you walk in steady.
The blue line is your stress through the day. When it crosses the dashed line, AcuSera responds. A workout or a small rise doesn’t set it off.
Simulated data, for illustration. Drag across the chart to move through the day.
The dot swells for 4 seconds as you breathe in, then fades for 7 as you breathe out. On a phone, you can feel it too.
Look back on your day whenever you like: your stress score, how fast you bounced back, and the times of day stress usually starts for you. No streaks to keep and nothing to log. Rather not look? You never have to open the app. AcuSera works either way.

A gentle vibration on your inner wrist at P6 that swells and fades in a slow wave: about four seconds up as you breathe in, seven down as you breathe out. The vibration therapy and the breathing guide are the same thing, happening at once. It starts barely there and builds gradually, so it never startles you the way a notification does. You can turn the strength down or pause it whenever you need to, and change the pattern in the app.
Most smartwatches and rings show you a stress score, and a few send an alert telling you to stop and breathe, usually at the worst possible moment. AcuSera doesn’t ask you to do anything. It responds on its own: when it detects stress building, it starts vibration therapy at the P6 acupoint, in a slow wave that guides your breathing. It also measures EDA, your skin’s sweat response, which most wearables don’t track.
It reads your heart rate, heart rate variability, EDA (your skin’s sweat response), skin temperature and movement together. Our model was trained and tested on lab stress sessions, and our clinical study will measure how it performs in everyday life. More on detection
No. AcuSera notices stress for you, and the vibration guides your breathing: in as it swells, out as it fades. No experience, no app to open and no quiet room needed. The gentle wave is also a quiet cue to notice your breath, your shoulders and your jaw. That’s mindfulness, without the session.
Yes. The default wave is four seconds in, seven out. In the app you can switch to box breathing (equal counts in, hold, out, hold), 4-7-8 (in for 4, hold for 7, out for 8), or slow breathing at around six breaths a minute. The research behind each
P6 is an acupoint on the inner wrist, between the two tendons. It has been used in acupressure for centuries and studied in clinical research for decades. AcuSera delivers its vibration therapy right there. More on P6
Yes. The AcuSera app shows your stress score, your stress moments, how fast you recover, and the times of day stress tends to start for you. You don’t have to use it: AcuSera detects stress and responds whether you open the app or not.
No. Stress detection and vibration therapy work without one. Premium adds extra app features, and Founders Club members get the first year included.
We expect AcuSera to launch between $299 and $399. The final price will be set before orders open. Founders Club members get $75 off whatever it is, and your $20 is fully refundable until you order.

No. The images show V3, our working prototype. The AcuSera you’ll wear does the same job in a smaller, lighter and more refined design.
The main unit sits on top of your wrist, where it reads your signals. The P6 module sits on the inside of your wrist, where the vibration needs to land and where the EDA electrodes read your skin.
AcuSera uses a small vibration motor, the same kind of part that buzzes in phones and smartwatches, and sensors that rest against your skin. If you have a pacemaker or other implanted device, or a medical condition, ask your doctor before using any wearable that vibrates.
No. AcuSera is a wellness wearable. It isn’t designed to diagnose, treat, or prevent any condition.
No. Keep following your doctor’s plan, and ask them before adding any new device to it.
