How does stock Trak work?

Can you explain how stock Trak operates? I'm curious about the functionality of this platform and how it helps users track their investments. Does it provide real-time updates on stock prices? Does it allow for customization of portfolios? Can users set alerts for specific price movements or events? Additionally, is there a mobile app version available for on-the-go access? I'd appreciate any insights you can offer to help me understand the benefits of using stock Trak.
