CrossFit Mayhem Athlete Dropped-In SPOTU

SPOTU is a fitness wearable device that has been developed and optimized for routine-based indoor exercises, such as gym workouts. It accurately monitors physical condition through the advanced wearable device and provides workout performance insights and solution for more effective self-coaching, exercise ability improvement and injury prevention based on a variety of data.

Existing smart devices such as smartwatches and fitness trackers in the market are heavily based on GPS technology and data for tracking workout activities.

While these devices are optimized for outdoor exercises such as running and cycling, they face many limitations for indoor exercise where posture and rep counting are more important measurement criteria. They also normally adopted PPG optical sensors for heart rate measuring, which have accuracy problem during intense exercises such as weight training, high-intensity interval training, etc.

We focused on these limitations and problems and started the SPOTU project to create a wearable device that contains powerful functions and high-end specs uniquely specialized for indoor exercises.

Many people often overlook the adverse effects of excessive workouts. If one does not consider their daily physical condition while exercising, it can severely damage their bodies. This is more prevalent with exercises that involve high-weight equipments like barbells. These exercises are so focused on achieving target goals for each session, people often go over their limits which in turn, can lead to major injuries.

During your workout, SPOTU allows you to check your heart rate level through LED lamp on the device. The ECG type Heart Rate Sensor in the device maintains accurate HR measurement even during the intense workouts. 

The color and flickering variations of the LED light represent your heart rate levels to let you know your current physical status immediately. It means you can control your pace for more effective athleticism growth and reducing injury risk.

One of the best ways to effective exercise is to watch and reference to other experienced people before jumping on to workout. This practice will help you pre-imagine and set-up your daily work-out activities in your head. But what could be more effective is actually watching yourself exercising and finding areas of improvements. This is the beginning of self-coaching and self-motivation.

SPOTU offers Real-time Performance Monitor and Augmented Video Recording features for your improvement. On the videos, information such as movement names, workout time, reps, total reps, rpm(reps per minute), HR bpm, body temperature are overlapped while recording your workout in real-time. You can check out the recorded videos with much more detailed indicators after workout.

The straightforward user interface of SPOTU makes it easy and convenient to check motion speed, pace, and movement consistency so that you can have decent training feedback by yourself even if you are not a fitness expert.

SPOTU analyzes the Youtube videos that are popular among the at-home fitness category as well as the Youtube channels that you’ve already subscribed to. The analyzed information and videos will be displayed in SPOTU application.

As SPOTU extracts workout details from the videos and saves them into database, you can learn about those details in SPOTU app without watching videos. You can search workouts that you like to do with just some keywords and also can get workout recommendation for your fitness level from SPOTU.

SPOTU is the chest strap type wearable device that maximize the accuracy of biometric data by utilizing ECG type heart rate sensor, respiration sensor and noise-minimized motion tracking technology.

Also, the SPOTU Motion Judging Engine, an in-house developed core technology, identifies and distinguishes user movements and counts repetitions of movements most accurately in real-time.

Among various types of data that SPOTU collects, linear acceleration and quaternion are motion data that show patterns and features when specific movements are repeated. SPOTU Motion Judging Engine raises the accuracy of analyzing these through the deep-learning method continuously.

Currently, SPOTU can recognize the composition and repetition counts of exercises like jumping jacks, burpees, high knees, air squats, planks, sit ups, push-ups, etc. SPOTU team plans to support more than 100 exercise movements from body weight exercises, weightlifting and gymnastics before the delivery.

On the SPOTU PRO spec basis, there are 4 types of sensors (ECG type heart rate, respiration, motion tracking, and temperature sensors) included in the device to collect biometric and motion data in real-time. Regarding the respiratory measurement sensor has applied advanced smart textile technologies based on the nano carbon coating of the MCELL. (US patent 16/081,875) Unlike other wrist strap type devices, SPOTU is a chest strap type device. We chose the chest strap type because the chest is the most ideal part of human body to collect motion and biometric data.

Press the button on the center of the device for 2-3 seconds to turn on the device. When it is on, there would be vibration feedback and blinking led circle lamp.

On your smartphone or tablet PC, enable bluetooth network, and run SPOTU mobile application. Follow the instruction of the app to sign up or log in, and connect to the device after the device registration on Profile tab.

Now, you can start your workout with SPOTU! While you exercise, SPOTU monitors and records your workout data on a real-time basis.

SPOTU devices and the mobile application are newly launched products by Spotu Technologies, Inc., which is a fitness gear brand and company that is created by exercise experts, software engineers, and hardware engineers. We, the Spotu team, assembled as we had shared the accuracy problem of existing fitness trackers and wanted to develop much more accurate and comfortable fitness gear. We have put our effort into this project for 3 years, and we are very pleased to introduce our product to backers for the first time.

The Spotu team has developed the hardware and software for those 3 years with 5 times of prototyping and 3 times of pre-production. We are ready to go for mass production along with sourcing parts right after the campaign done. 

The reason why we have taken 3 years for the campaign launching is that we wanted to launch our product when the mass production process is ready. After all those prototyping and pre-production, the supply chains and delivery means are secured, and we are so ready to produce and deliver our products within 5 months right after the campaign ends. For the quality control and assurance, whole producing processes will be done in South Korea, and products will be delivered to all over the world.

Risks and challenges

The SPOTU took extensive time to research and develop as it required various technologies.

We faced many challenges in the process of making this product, but we are giving our best effort to produce and deliver products that possess top-notch quality and technology on Indiegogo.

Nevertheless, when unexpected situations such as issues in procuring parts and delayed delivery occur, we will inform you of them through prompt updates. With long-standing experiences and know-how, we will make sure to provide the best products and accurately deliver them to you on time.
