IoT-Enabled Mobile Demo App for Smart Sports Apparel

Heart rate tracker, pedometer, and calorie counter

The client developed a PCB to embed into sports apparel. They wanted to upgrade the solution so that an athlete could obtain data on their physical state.

More Details


Softeq was employed to help turn the client’s solution into an IoT system. We undertook the project to develop a mobile demo app for performance tracking.

A PCB embedded into smart garments would send athletes’ health parameters to an Android mobile app and smartwatch.



Softeq developed a smart apparel solution that works with sensors embedded on the inner side of clothes, including tank tops, gym shirts, pants or underwear. The system consists of a heart rate measuring device, sensor-rich sports garments, and Android-powered watch and mobile app that exchanges data with sensors over BLE.

The mobile software app prototype is a feature-complete demo app integrated with the client’s custom BLE environment. The solution allows for measuring heart beat and pulse rate, steps, distance and calories burnt. Lightweight and password-free, the application keeps the stats chart available immediately. The Android wear app supports the same stats set (except for pulse rate) and shows it in numeric output.

High precision of heart rate detection was a strong evaluation factor, so the team carried out a dedicated analysis on the heart beat data quality. Given that the system was to integrate with existing device and firmware built on the customer site, Softeq focused much on fine-tuning the data transmission stability. As long as built-in electrodes captured much noise, the team furnished the app with filtering algorithms that help identify heart rate.
