Coinbase has an incredible UI. I've used a lot of investing apps like Robinhood, Webull, etc. These apps have a lot of clunky options and buttons, and although both Robinhood and Webull aim to simplify investing, I believe they actually complicate it. Coinbase, on the other hand, through their lean and clean structure, make investing easy to learn and to understand. Intuitively, the user's account balance and crypto watchlist is displayed on the home page, and only four options are shown on the menu. The app is easy to navigate and because it's so simple, the UI accentuates and highlights the purpose of the app-- to help users buy crypto + to increase their financial freedom-- rather than preventing users from achieving the purpose.
