Frequently Asked Questions

Yes. The device has a water resistance rating of 5 ATM. This means you can swim while wearing the band, provided you do not dive too deeply. Avoid salt water and strong jets of water, as these can damage the band’s waterproof seals.

Unlike GoBe3, GoBe U has a minimalist design with no screen. The band is 20% lighter, slimmer and more comfortable on your wrist. The sensors have been reshaped for greater comfort, and the new design makes the band barely noticeable during continuous wear.

Charging is much easier: the cable automatically turns to the correct orientation and attaches with magnets. The updated power system provides 50% longer battery life, up to 48 hours.

The main features, including calorie tracking and heart rate, hydration and sleep monitoring, remain the same, but we plan to add several exciting new features. In the future, GoBe U will let you take an electrocardiogram, measure blood oxygen levels and check body temperature whenever you need to. The band also has more memory, a new optical sensor, full water protection and updated vibration feedback.

Unlike other bands, GoBe continuously measures all 35 lifestyle indicators at intervals ranging from 10 milliseconds to 5 seconds, 24 hours a day, 7 days a week. This helps provide the most accurate possible data about the key aspects of your body and lifestyle.

On a full charge, GoBe U can operate for up to 48 hours.

The previous model, GoBe3, operates for up to 32 hours on a single charge.

For the most detailed and accurate data, we recommend charging GoBe when your body is not digesting food, for example, in the morning immediately after waking up.

Syncing the band with the app too often drains the battery, so we recommend syncing once or twice a day.

The external surfaces and materials used in GoBe U are listed below:

• Case base: polyamide with a modified glass fiber additive (PA+60%GF).
• Case cover: polyamide with a modified glass fiber additive (PA+60%GF).
• Bioimpedance sensor contact pad: titanium (Ti).
• Heart rate sensor lens: transparent polyamide (PA CP9020 NC1005).
• Band: hypoallergenic silicone.

When you eat, your body begins to digest food. As glucose enters the bloodstream, cells start to absorb it and release water in the process. This causes fluid to move between cells. A bioimpedance sensor detects these changes. Bioimpedance measurement has been known since the late 19th century, but GoBe was the first to implement it in a wearable device.

The HEALBE FLOW algorithm analyzes the collected data to:

• Track changes in the electrical conductivity of tissues.
• Build an individual glucose curve.
• Calculate how many calories have been absorbed based on that curve.

GoBe U shows when calories are absorbed, rather than simply when you eat. Different foods are absorbed at different rates:

• Simple foods, such as sweets, may begin to be absorbed after 15–30 minutes.
• Most food reaches the bloodstream after 3–4 hours.
• Complex meals with meat and side dishes may take 9–10 hours or longer.

Absorption phases can also overlap, with one meal still being digested when the next begins.

The device records not only calories from food but also energy from the body’s internal reserves, for example:

• During dieting or fasting.
• During physical activity.
• During long intervals between meals.
• At rest, including during sleep.

This means the band may show calorie absorption even when you have not eaten. This is normal and reflects the actual state of your metabolism.

The latest studies related to FLOW technology were conducted in the United States and China. A brief overview of these studies follows.

United States

In fall 2018, the University of California, Davis, Institute of Nutrition conducted a study of GoBe bands’ ability to track absorbed calories. The researchers compared the device’s accuracy with manual calorie counting.

Twenty-seven volunteers wore GoBe smart bands for 14 days under specialist supervision. To assess average daily calorie intake, the data were grouped into three-day intervals. The GoBe readings and manual calorie counts based on food diaries differed by 10%.

HEALBE GoBe therefore demonstrated accuracy of up to 90% among healthy adult volunteers, with accuracy defined as 100% minus the 10% error.

China

In late 2018, Guangzhou Red Cross Hospital conducted a pilot study of the calorie tracking function of GoBe smart bands. Volunteers were asked to wear HEALBE GoBe for two weeks. The data were grouped into three-day intervals to assess average daily calorie intake.

In this study, the average daily absorbed calorie value measured by GoBe and the results of manual calorie counting differed by 16%.

More detailed information about these studies is available on our website.

You can also explore our patents at worldwide.espacenet.com.

The patent list includes, but is not limited to:

• A method for detecting water deficiency in the human body.
• A method for measuring the glycemic index of food consumed by a person.
• A method for determining the phase of human sleep that is favorable for waking up.

And many others.

HEALBE GoBe measures calories burned by calculating two types of energy expenditure: basal metabolism, the calories your body uses to maintain vital functions even at rest, and physical activity, which is measured using a 9-axis accelerometer and a heart rate monitor.

GoBe currently recognizes only walking and running. Data may be incomplete for activities with limited arm movement, such as cycling, strength training and roller skating.

Yes. The automatic learning process for the band’s various features can take anywhere from a few hours to several days. This depends entirely on continuous wear, so we recommend removing the band only to charge it. GoBe uses algorithms that learn from your body’s data, so the longer you wear the device, the more accurate the results become.

In general, the accuracy of absorbed calorie tracking and other measurements improves significantly during the first 24 hours of use because of several factors that are unique to each person:

• First, metabolic processes are affected by many factors, including the amount of food consumed, physical activity, stress levels, sleep quality and how long the user’s stomach has been empty.
• Second, different foods are digested and absorbed at different rates. Calorie peaks in the GoBe app do not always appear at the exact time you eat. They may appear later, as slowly digested foods are used by your body.

As GoBe learns the characteristics of your physiology, calorie absorption data becomes increasingly accurate.

GoBe currently supports integration with Apple Health and Google Health Connect. By using these apps to aggregate data, you can transfer it to any other app that works with a standardized format for health and lifestyle data.

Please note that although HEALBE bands are designed to provide information about the conditions and trends in your body’s physical state, they are not intended for use as medical devices and must not be used for diagnosis, treatment, disease prevention or as a substitute for professional medical advice.

The physiological model used in HEALBE bands is designed for healthy adults with a mixed diet. Significant deviations from typical health conditions or diet, such as keto or paleo diets, may reduce the accuracy of GoBe measurements.

GoBe measurement errors may increase under the following conditions:

• During pregnancy or breastfeeding.
• In people under 13 or over 65 years of age.
• With disorders affecting water and electrolyte balance, the cardiovascular system or endocrine glands, as well as metabolic disorders and mental health conditions related to eating habits.
• When taking medications that affect water and electrolyte balance, cardiovascular function or metabolism.
• With major deviations from normal air humidity or atmospheric pressure.
• In other situations that differ significantly from normal physiological conditions, such as an unfamiliar climate, several sleepless nights in a row or an abrupt change of time zones.

Not all conditions outside the normal medical range affect readings in the same way, and the list above is not exhaustive. If you are unsure, email us at gobe@healbe.com or use the chat on our website. We will be happy to answer your questions!
