Detects stress. Relieves it automatically.

A wearable that catches stress as it builds and responds on its own, with vibration therapy at the P6 acupoint in a slow wave you breathe along with.

01 / Reads

Reads your body, all day.

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.

  • Heart rate
  • Heart rate variability
  • Electrodermal activity (EDA)
  • Skin temperature
  • Motion
02 / Recognizes

Measures the stress signal most wearables miss.

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.

How AcuSera detects stress

03 / Responds

Vibration therapy at P6, in a wave you breathe with.

When stress builds, AcuSera starts vibration therapy 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, so you can keep doing what you were doing.

04 / V3

This is V3. Yours will be smaller.

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.

See how it works

Your watch already knows you’re stressed. It tells you later, in a graph.

By the time you check the score, the meeting is over and the moment has passed. AcuSera does something about it on its own, while it’s happening.

Made for the moments you can’t step away from.

Stress rarely waits for a quiet minute, and you rarely have one to give it. Three moments AcuSera is built for.

8:52 AM

Before you feel it

Your body often reacts before your mind catches up. Heart rate and sweat response start climbing while you’re still reading emails. AcuSera responds to the early rise, while it’s still small.

2:14 PM

When you can’t step away

No time or space to open a meditation app. In a meeting, on a shift or in class, AcuSera responds right on your wrist. No screen, nothing to tap, and nobody else notices.

7:40 PM

Before the big moment

The game, the exam, the set. 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.

Watch a day through AcuSera.

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.

Built on the science of stress relief.

12randomized trials, 785 people: breathwork lowered self-reported stress
223studies: slow breathing raised the heart rate variability linked to rest
59trials in a Cochrane review of stimulating the P6 point

AcuSera combines approaches researchers have studied for years: rhythmic wrist vibration, the P6 acupoint, and slow, paced breathing. Now we’re testing AcuSera itself, with our own clinical study alongside academic medical researchers.

Built by someone who needed it.

Zaydan Ahmed, founder of AcuSera
At sixteen I had my first stress-induced epileptic seizure, behind the wheel on the highway. My car flipped four times. I walked away, and learned stress was my most consistent trigger.

Every wearable I tried could tell I was stressed. None of them did anything about it in the moment, when I was mid-conversation, in class or on the field. So I’m building the one that does.

Questions.

What does it feel like?

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. You can change the pattern and the strength in the app.

How is it different from my smartwatch?

Most smartwatches and rings show you a stress score, and a few send an alert. AcuSera 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.

How does it know I’m stressed?

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

Can I change the breathing pattern?

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

Why the P6 point?

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

Is there an app?

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.

How much will it cost?

$299 planned retail. Founders Club members get 10% off.

What happens to my $10?

It’s credited toward your AcuSera when you order. If you change your mind, email us and we’ll refund it.

When does it ship?

We’ll announce the ship date when orders open. Founders Club members hear it first and get first access.

Is the device in the photos the one I’ll get?

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.

Why two parts on the strap?

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.

Is it safe to wear?

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.

Is this a medical device?

No. AcuSera is a wellness wearable. It isn’t designed to diagnose, treat, or prevent any condition.

Does it replace treatment or medication?

No. Keep following your doctor’s plan, and ask them before adding any new device to it.
