What does blur app do?

Could you elaborate on the functionality and purpose of the Blur app? I've heard about it in the cryptocurrency community, but I'm not entirely clear on its core offering. Is it a wallet, a privacy tool, or does it offer something else entirely? How does it protect users' financial data and transactions? And is it specifically tailored for the crypto world, or does it have broader applications? I'd appreciate a concise yet comprehensive description that highlights the key aspects of this app.
