What is TokenPocket app?

Could you elaborate on the TokenPocket app? I've heard it mentioned in the cryptocurrency community, but I'm not entirely sure what it does. I'm interested in understanding if it's a wallet, an exchange, or perhaps a tool for managing my digital assets. Specifically, I'd like to know about its key features, such as its security measures, supported blockchains, and any additional functionalities it offers. Additionally, is it available on multiple platforms, like mobile and desktop? And lastly, how does it compare to other popular cryptocurrency wallets in terms of user-friendliness and performance?
