What is the toshi website?

Could you elaborate on the purpose and functionalities of the Toshi website? As a crypto enthusiast, I've come across various platforms but haven't delved deeply into Toshi. Is it a wallet service? Does it offer trading options? Or perhaps, it's a platform for decentralized applications? Clarifying its CORE offerings would help me understand its significance in the crypto landscape. Additionally, is it user-friendly? And how secure is it compared to other similar platforms? Answers to these questions would greatly assist me in evaluating Toshi's potential.
