There are other similar apps/services as well like Wealthfront. These are called "robo advisors". They are made for people who are either new to investing or people who just want to invest as hands off as possible.

You can set up recurring deposits, and add goals that it will automatically tailor your risk level/asset mix to achieve.

I would recommend looking into it. I started out using it just putting a few hundred bucks in. They also have a high yield savings account that I put most of my emergency cash in because its a lot higher interest than my standard savings account (though the rate used to be a lot higher).
