Gymetryx has developed a patented, easily transferable pod device, TopEx, that turns a weight-training machine into an IoT-compatible advisor. The TopEx is enabled to monitor and measure the fitness equipment's weight-loss effectiveness. When users are working out on the weight machine, TopEx monitors the users' change in weight. The Gymetryx app reports and analyzes users' performance in real time, supporting exercise at the proper speed to reach the requested weight.
