Here is a smart wearable system that helps you become a better swimmer. It has a base, wristband, and an app to help you keep an eye on your performance. The base is capable of showing 6 parameters. It can be mounted on any pool wall and connect to the wristband wirelessly.
Swimmerix collects data in real time and transmits it to the base. You will be able to keep an eye on your heartbeat, laps, strokes, time, distance, calories burned, and other information. The wristband uses color codes to keep you on track in the pool. Yet another smart training tool for swimmers.
