I've been back and forth over robinhood vs fidelity vs IBKR for a few years now. I do not do any heavy day trading, but I do like to buy a few shares of things throughout the day, every day. As a consequence, the user experience in mobile form factor is a big aspect for me. I understand for any professional in the space, this is perceived as lunacy. I am no professional. Once IRA support is added, I'll be locked in for life. I don't understand how someone can use the fidelity or IBKR mobile apps and think "yes this is all ok" after spending 5 minutes in the RH app.
