I looked into other products, but felt that none of them addressed my particular use case. Felt like they were designed for someone very different than myself. Anyway, if there is some good alternative I don't know about (which is extremely likely), please suggest.
Or you can buy ETF versions of Vanguard funds. Same expenses as mutual fund versions, but the minimum purchase is 1 share. Free to trade from a Vanguard account (or something like this Schwab account, since its exchange traded).
Many of their funds also have corresponding ETFs, and I've found that most (all) have similar or lower expense ratios, and the minimum buy is a single share (of course, you can't buy fractional shares like you can with mutual funds, so that can be annoying).

One reason I dislike Robinhood is that it seems to encourage speculative trading behavior as opposed to a proven long-term investment strategies. I don't care about free commissions much, because the only equities that I care about (index fund ETFs) are already available for free. I don't care at all about buying individual stocks. I don't care about buying cryptocurrencies either. And I don't care about cash management (y'know Robinhood, I have a real bank account that is actually FDIC insured, unlike the half-baked "savings" accounts you tried to sell us on) So for me, I actually greatly prefer using a more traditional brokerage that offers me exactly what I want and has a proven track record.
I don't like their cash balance for their robo-investor. But then again most "robo-investors" are 100-500 line python lambda scripts that run on timer if a hypothetical trading api module existed
