I've been interested in the Robinhood app as well. I don't like that their philosophy is built around social stock picking with a day trading mentality, but most brokerages are built like that. It's good that they're putting downward pressure on brokerage commission fees.
I plan to try it out anyways once they have IRA capabilities and not just taxable accounts.
Fees shouldnt be much of a concern for you, so many free etfs, or big breaks like BofA where if you have something like 100k across all accounts theyre free, etc..
