What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

 < It Is SIMPLE to USE Fitrus Plus™ >

 < WHY Fitrus Plus™ >

Being Healthy is NOT about...   

  • being thin or losing weight
  • excessive cardio
  • eating greens
  • starving yourself with impractical diets  
  • what your step counts reads on your smartwatch or mobile device


< Being Healthy Starts with Fitrus Plus™ >

 "It all STARTS with knowing what your body is composed of"

 1. Body Fat (%) and Skeletal Muscle Mass determine how you look, not your weight.

  • Your appearance is in DIRECT correlation to the amount of fat your body holds in store as well as how much skeletal muscle mass you have developed over the years.
  • Your CONCERNS: cellulite, flabby arms, muffin tops. These are the outcomes of a high body fat percentage.
  • Those who are "skinny fat" seem healthy and thin in their outer appearance but due to their high body fat perentage and very little muscle mass, they have the metabolic rate and health risks of an obese person. "Skinny fat" people also tend to hold most of their fat in their abdominal area despite their low or average BMI.

2. Your weight on the scale means NOTHING. Your body composition will give you a qualitative understanding of your health.

  • Scale readings represent your total body mass: internal organs, muscles, bone, blood, fat, etc. 
  • DO NOT be deceived by your scale reading for it does NOT represent your health.
  • Instead, FOCUS on the individual components of your body composition, especially your body fat percentage and skeletal muscle mass.
  • Low body fat significantly reduce the risks of developing chronic health diseases (Coronary Heart Disease, Diabetes Mellitus, Hypertension, etc.)
  • High skeletal muscle mass will reduce the risks of developing Osteoporosis, Arthritis, as well as a reduced risk of injury (low back pain, knee injuries, etc.) due to developed proprioception as well as optimal neuromuscular efficiency.

3. Body Fat (%) and Muscle Mass determine how SUCCESSFUL you will be at weight management.

  • STOP attempting impractical diet plans or excessive cardio to lose weight.
  • Starvation will significantly slow down your metabolic rate and deteriorate your muscles. Although you may decrease your body fat mass, you will completely jeopardize your health and well being.
  • Allow Fitrus to give you the guidance you need to manage your weight.

< What is Fitrus Plus™ >

 Fitrus Plus™ is a pocket-sized device that measures and analyzes your body composition anytime, at any place. 

  • Efficiently manage your results through our FREE mobile application, available on both the Google and Apple App store. 
  • With consistent measurements, a graph will be provided for each component of your body composition to display your progress over time.

< Features of Fitrus Plus™ >

< Fitrus Plus™ Mobile App Features >

< How Fitrus Plus™ Works >

Fitrus Plus™ uses Bioelectrical Impedance Analysis (BIA) to measure body composition, in particular body fat. Only now, instead of having to use a cumbersome machine, we offer you a powerful device that fits in the palm of your hand.

BIA is a method in determining body fat compositions by measuring how easily a tiny electric current flows through your body tissues, or to be more precise, the opposition, or “impedance” to the flow. 

< How and when to use Fitrus Plus™ >

Fitrus analyzes in real time, and the electrodes are purposely quite sensitive to your hydration levels. 

  • Therefore, Fitrus Plus should be used first thing in the morning before any activity or food intake. 
  • Taking a measurement after a meal or excessive hydration would result in an overestimation of your lean body mass and thus an underestimation of your body fat percentage.
  • On the other hand, taking a measurement after working out or dehydration would results in an overestimation of your body fat percentage.

 < Special Tips for Fitrus Plus™ >

Fitrus Plus measures resting heart rate (before or after exercise) as well as your peak heart rate (during exercise). A lower resting heart rate signifies a good cardiorespiratory system and your peak heart rate will represent your intensity level during your workout.

The average resting heart rate is 60 to 80 beats per minute; a resting heart rate of 100 or more indicates tachycardia, which predisposes a person to complications such as a stroke or heart failure. Tachycardia requires regular monitoring and follow-up. Fitrus Plus can record when tachycardia occurs - for example, during stressful situations or after a workout - so your doctor and you can monitor and treat accordingly. Get Fitrus Plus to be more aware of your body including your cardiac health!

Introducing our Passionate Team

 Our Company Overview

Why Kickstarter

As shown above, we have had the honor of winning awards and gaining recognition, and were able to raise money for our prototype and patent development. Now, we need your support to bring Fitrus to the widest audience possible. We will use the funds raised on Kickstarter to:

Manufacture: Like all creators, we need to meet a minimum financial commitment to get started on a manufacturing run. This is why we have set our funding target at $30,000. By helping us reach this goal, you enable us to provide Fitrus to those eager to take action in leading a healthier lifestyle!

Testing: We are constantly improving the Fitrus algorithm and user interface. Doctors, scientists and engineers are on our team. We will continue to find ways to improve until the product launches in August 2018.

Quality: You’ll be getting the best Fitrus engineering can create. We make improvements as soon as they become possible.

Tooling: Producing Fitrus requires various manufacturing resources. Investments here yield products that last for years. We want your Fitrus to be as robust and resilient as possible. 

Risks and challenges

As with any hardware project, there are always schedule risks associated with manufacturing and supply chain logistics.

The OSD team has successfully delivered thousands of our device to all over the world. We understand the unique challenges of device that measures body composition and are familiar with how to avoid and mitigate any issues that arise. Additionally, we spend 2 years, 0.4 million USD, and 10 patents went into develop our product.
