Are you any good at investing? Is your financial advisor doing well for you? These questions were pretty hard to answer until Openfolio came along in 2014.

Openfolio allows you to compare your portfolio's performance (daily, weekly, monthly, yearly, etc.) with that of 70,000 other investors. You can see their returns and asset allocation (i.e. the percentage someone has in stocks, bonds, gold, Apple stock, etc.) even though you won't know how much money they have invested.

The app is free. You simply connect your brokerage and retirement accounts and then Openfolio figures out your performance and shows you how you stack up.

The idea is if you suck compared to your peers, you'll be motivated to make a change.

"We call this 'peer pressure for good,'" says CEO and founder Hart Lambur.
