11 / WHY THE VAGUS NERVE?

Your day's over. Is your body still busy?

Sometimes tension stays with you even when you're resting. AMOFIT focuses on the signals that help the body coordinate activity and rest.

Conceptual view of the vagus nerve connecting the brainstem, heart, lungs, and digestive organsBrainstemLungsHeartDigestive organsVagus nerve pathways

Your body needs a rhythm for rest, too.

The autonomic nervous system is involved in functions you don't consciously control, such as heart rate, breathing, and digestion. The sympathetic and parasympathetic nervous systems work together to coordinate the body's response to different situations.

Sympathetic nervous system Activity and response
Parasympathetic nervous system Rest and recovery

The vagus nerve is a major nerve that extends from the brainstem to the heart, lungs, and digestive organs. As an important pathway of the parasympathetic nervous system, it carries information between the brain and body.

AMOFIT has been researching non-contact vagus nerve stimulation technology to make this connection easier to work with in everyday life.

14 / READING THE SCIENCE

Beyond how it feels. Into the body's signals.

Heart rate variability, brainwaves, melatonin, and self-reported sleep. Different measures offer different perspectives on changes in the body.

ECG · HRV / HF

Changes related to autonomic activity

The high-frequency component of heart rate variability, calculated from an ECG. It is interpreted in relation to parasympathetic activity, and is also influenced by breathing and measurement conditions.

EEG · ALPHA

Relaxed wakefulness

A frequency band of the brain's electrical activity. It is associated with being awake and relaxed.

MELATONIN

A signal of sleep rhythm

A hormone associated with the body's nighttime circadian rhythm. The research measured salivary melatonin at specific times.

ISI

Sleep difficulty as participants experience it

A self-reported Insomnia Severity Index. A lower score means participants report less difficulty with sleep.

The studies below are human studies of the previous-generation AMO+, which used the technology underlying AMOFIT.

15 / THREE HUMAN RESEARCH PROGRAMS

Three studies. Deeper questions.

Two human studies at KRISS (Korea Research Institute of Standards and Science), and one at Kyung Hee University Medical Center in South Korea. Explore what each study measured and the changes it observed.

01

Kyung Hee University Medical Center · Sleep research · 2020

Sleep rhythm, and the sleep difficulties people actually feel.

The sleep research at Kyung Hee University Medical Center in South Korea examined melatonin and ISI. Melatonin is a biomarker related to sleep rhythm, while ISI assesses the sleep difficulties participants experience. In the results of a 30-day sleep program published by AMO Lab, the mean ISI score decreased from 15.7 to 8.15 at day 14.

Mean ISI · Change at day 14

ISI score ranges and where the means fall

29 / GOOD QUESTIONS. CLEAR ANSWERS.

A few good questions before you start.

From wearing it to the app, research, and delivery. Find the answers you need in one place.

Does it need to touch my skin?

No. Wear it over your clothes near your upper chest, using the necklace or clip. You don't need to prepare skin electrodes or conductive gel.

Should I use the necklace or the clip?

Choose whichever feels comfortable for your clothing and activity. Adjust the necklace length, or attach the clip to a collar or opening, so the device sits near your upper chest.

Do I need the app and a smartphone?

The core features work with the device alone. Connect to AMOS APP optionally when you want more detailed settings and usage history. Audio tracks and headphones are not required.

Is there a monthly subscription fee?

There is no required subscription fee to use the device and basic AMOS APP features.

How long is each session?

The default standalone session is 3 hours, after which the device switches off automatically. In AMOS APP, you can set session duration and continuous operation. Follow the product guide for recommended session lengths and frequency for each mode.

Do I need to wear it while I sleep?

A routine for better sleep can begin as you unwind before bed. Follow the user guide on whether and how to wear the device during sleep.

When might I notice a change?

The degree and timing of changes may vary with your physical condition and lifestyle. Based on the experiences customers have shared so far, most report noticing positive changes within 30 days of use.

Is it working if I don't feel stimulation?

Check power, mode, and session status using the device's status indicator and AMOS APP. Feeling strong stimulation is not the measure of whether it is working.

How long does the battery last, and how long does charging take?

It is designed for 20+ hours of standalone use or 13+ hours with the app on a full charge. USB-C charging takes approximately 1.5 hours. Actual times may vary depending on settings and conditions of use.

Does AMOS APP measure sleep or stress?

AMOS APP manages modes, session duration, and usage history. It does not automatically measure sleep, stress, or HRV.

Where can I download AMOS APP?

AMOS APP supports both Android and iOS. Download instructions and a connection guide will be provided with AMOFIT S Pro launch information. The device's core features work without the app.

Can more than one person use it?

One device is designed to be shared by multiple people. By registering separate accounts in AMOS APP, each person can manage their usage history separately, without mixing records.

Were the featured studies conducted with AMOFIT S Pro?

The completed human studies examined the previous-generation AMO+ and its underlying technology: two KRISS studies and one melatonin and ISI study at Kyung Hee University Medical Center in South Korea. The two academic papers let you explore the research methods and findings.

Are results available from the U.S. university study?

This ongoing clinical study with North Carolina A&T State University received U.S. IRB approval in 2026 and is registered under protocol HS26-0026. It examines cardiometabolic health, stress resilience, and gut microbiome composition. Results have not yet been published.
