The biggest broker in the world?
I use both Robinhood and Schwab, and the Robinhood app is absolutely terrible.
The visual aesthetic is nice, but usability is awful... I don't really understand the hype. For example they have no dedicated orders screen to cancel limit order that I can tell. There's an "inbox" where your limit order will show up after some delay. I placed an order once and decided to cancel it, but the inbox message didn't show up for 5 minutes, so I had no way to cancel it.
Also you can't see older than 5? years on stock charts. Or zoom or anything, only specific presets.
Finally, I bought a small amount of crypto, and did a market order sell once, and my fill price was like 10% under current market value. Obviously market orders are bad, but most brokers have safeguards that prevent executing them at such a difference from last traded price.
Anyway, bad experience all around. I imagine the only people who use it seriously are those that haven't tried more serious brokers, or that don't know any better.
The idea behind Robinhood is good, but it could be done so much better. So many obviously bad design elements
