Horrible execution. EXTREMELY laggy after you chose options. Also, whoever authorized the design of this app clearly isn't a trader. If you're a long term investor, this is for you. If you are trader, selling covered calls or anything remotely more than a few times a month, let alone a few times a week or day, this is not for you. Even the mobile website is better than the worthless app. Robinhood is so much friendly to trade and keep track of profits. Stick with Robinhood instead.
