M1 Finance is another one. You don't need to trade at all. You just set your target allocation as percentages ("slices" of a "pie"), and M1 triggers the necessary buys and sells, which are also done as synthetic fractions of shares. It's all executed as market orders; you never see the trading. I don't use M1, but I think it's a much better model when you just want to manage something like a three-fund portfolio. This is how employer plans like 401(k)s work, after all. You set the target allocation and all the trading and rebalancing happens behind the scenes. Traditional brokerages like Schwab and Fidelity are really behind here in terms of UI. There's no technical reason not to offer a UI to automate target allocation.
