What are good apps for investing into the stock market?

I’m a recent college graduate and I want to start investing into the stock market. Just for the sake of convenience I’d like to have an app on my phone where I can do that. But all the apps I check have bad reviews about poor customer service. I know there will always be people who have bad experiences no matter how good the service is, but I still want to find a good and safe choice. I’m basically just looking for the simple ability to trade and monitor stock prices. Though ideally I’d like for there to be some virtual “practice” money available so I can test out my stock trading abilities before actually investing (fake money kinda like a game). Thanks in advance for the help!
