Analysis & Guidance
You should first check your body composition to take care of your health.
It’s unlikely for people to have large and expensive standard body composition analyzer device at home to use.
Moreover, unless you’re always at the fitness center or the hospital, it’s inconvenient to visit those places every time you want to use it.
It’s a pocket sized device with excellent portability.
With this device, you can just measure and analyze your body composition at home or even when you’re traveling without having to visit the healthcare center.
Our device raises awareness of your well-being beyond recommending workouts.
Connecting the device to the app allows you to check your body condition every day.
It basically acts as your personal trainer!
Now, start your healthy life.
Motivation for Fitness
The app provides various contents and gives tips as you go for your goals.
The app saves your body composition and bio-data in the cloud-based platform for it to be analyzed.
Device uses this data to provide a personalized service through the app.
It analyzes your body composition, body shape, and even suggests appropriate meal plans and workout routines, which differentiates it from the existing body composition analyzing apps.
Provides suitable health comments based on your results as well as the most appropriate exercise for your body.
You can effectively manage your health since the recommended exercise also changes based on your changed body composition.
Line charts on the app allow you to intuitively see the change in your body.
Device is the best gym mate as well as a personal trainer.
Even though it is easy for people to give up on exercise and diet, device motivates you to exercise and diet by showing visible changes in your body.
Device supports you psychologically and suggests.
The app distinguishes the somatotype based on ONESOFTDIGM’s self-researched body composition.
It divides users into 3 body types, 25 specific subtypes, and provides a total of 139 comments regarding the health condition.
The app prevents you from following impractical meal plans that ruin your health by providing dietary reference intakes.
Many people who diet and workout normally keep track of their routine by writing it down.
Most wireless devices need to be connected to Bluetooth every time you use it.
However, Device doesn’t require the standard pairing process because it has adopted the Bluetooth 4.0 BLE technology.
With this technology, the device connects to the phone and the application automatically when you turn on the device.
The device can also measure the body composition in 5 seconds, which allows you to check the data on your app right away.
How does it work
Algorithm using Bioelectrical Impedance Analysis (BIA)
Bioelectrical resistance analysis focuses on the fact that muscle contains water while fat doesn't.
If you lightly hold the electrodes of the Device with both of the thumbs and index fingers, it sends a harmless amount of micro electric current to the upper body (the lower body is corrected by the algorithm) and checks the resistance value of the body parts that the electric current cannot be flowed for capturing the body fat.
Depending on the amount of water in the body, the degree of electrical passage, or resistance, will vary.
The point is that the electric current can be flowed in the water, but cannot in the fat.
Also, through the ONESOFTDIGM self-developed algorithm, the amount of skeletal muscle mass, basic metabolic rate, and body water which involves the development of the body is calculated.

Bioelectrical Impedance Analysis (BIA) is a highly safe and efficient method of analyzing resistance values inside the body.
For more accurate measurement results, we developed an algorithm by utilizing BIA and applied it to Device.
In addition, we continue to study algorithms using the collected data and reflect the results directly into the app.
However, since body composition is analyzed based on the principle of measuring the resistance value through body water, the result can be changed if there is a change in the water level due to fluid intake, pregnancy, and exercise.
Therefore, measuring at the same time, in the same position, with the same body condition (water and food intake) may improve the accuracy of the measurement.

What's in the Box
Fitrus T is comprehensive platform is powered by pocket-sized devices, tablet kiosk and web services along with various digital health and wellness contents.
USB to Micro 5 Pin Cable
We developed the body composition measurement technology to help people build good habits for managing their health based on our accumulated data.
We focused on our development to standardize the practice of analyzing body compositions.
In July 2013, we’ve also released a dissertation on how our device demonstrates 98% accuracy compared to professional medical devices.
After putting in 4 years of our effort, we finally launched the portable body composition analyzer ONESMARTDIET in September 2015.
After releasing ONESMARTDIET, we were able to reach out to customers internationally through exhibitions in various countries, global crowdfunding, and online and offline sales, in which we received a lot of interest.
After gathering diverse opinions on our device, we began the development of the next device in 2017.
We are happy to introduce device, a pocket-sized health and fitness tracking device that measures, analyzes, and timely reports accurate biometric data along with various digital health contents to Unmask the New You.
Our goal is to allow people to easily measure their body composition and use the collected data to create good health managing habits.
