What does Astro app do?

Could you please elaborate on the functionality of the Astro app? Specifically, what services or features does it offer that make it unique in the cryptocurrency and finance space? How does it cater to the needs of users interested in this domain? Is it a trading platform, an information aggregator, or perhaps a combination of both? Additionally, are there any unique benefits or advantages that the Astro app provides to its users? I'm curious to know more about its capabilities and how it stands out from other similar apps in the market.
