Binance.US - Bitcoin & Crypto is a cryptocurrency trading application available in the AppStore but only usable in the US. I found several issues while using the app, including incorrect validation, overlapping texts, and hardly-readable hints. I also discovered some major JS and connectivity errors. Fixing these errors will make the app much better.
