How many times have you been sitting in ungodly heat just wishing you had a pool in your backyard to cool off in?

Tim Snyder had a problem shared by many homeowners across the country: An expensive swimming pool that goes unused most of the time. Snyder signed up for Swimply, an app that matches people who own pools with people who want to swim in them. “Before long we had thousands of strangers swimming in strangers' pools.”Greg Teegarden listed his pool on Swimply just a few weeks ago. “At first I thought it would be like grocery money - but it’s been that and more,” he says. Some have made it illegal to rent out your pool or require a permit.

Swimply allows users to look up private pools in major cities that are available to rent by the hour. It's a great way for people who don't own pools to have a little summer fun, and it gives pool owners a way to earn some extra income. The company currently has pools available in 20 states across the United States, with more to come as the website becomes more popular. The price to rent a pool by the hour isn't as expensive as you might believe. If you split the cost among a couple of friends it won't be wildly expensive.
