Betterment is easy but if you have more than a few thousand bucks to invest I would just open a Vanguard account and put your money there. If you have no idea what you're doing just use a target date fund, otherwise just buy stock/bond ETFs in the mix that you want. Not worth ~0.4%/year in fees (doesn't sound like a lot until you realize it's $400/year on $100K) to have someone else do that for you.
