What is the dig in app?

Could you please explain what the dig in app is exactly? I've heard about it, but I'm not quite sure how it works or what it's used for. Is it a cryptocurrency wallet? A trading platform? A way to invest in digital assets? I'm curious to learn more about its features and how it differs from other similar apps in the market. Can you provide me with a concise yet informative overview of the dig in app?
