Between buying the phone and paying your phone bill, owning a smart phone can drain your bank account.
So when we heard there were apps that claim to be able to make you money, we were intrigued.
"It does sound too good to be true," said Karri Baumann of St. Louis.
That's what we thought too. But Jacqueline Sutt proved us wrong.
"I've made $4,500," she told us.
Sutt's been using apps like Field Agent and Gigwalk for years.
Send you to a nearby store to complete a few tasks and pay out an average $4 to $6 per job.
"An average gig is you look for a specific item in whatever store they want you to go to. You take a picture of that item and answer questions about that item," said Sutt.
We tagged along with Sutt on one of her gigs.
Ten minutes and a few pictures later, Sutt was $4 richer.
"It's not going to make you full-time job money, but it's going to give you some extra cash," she said.
And then there's Mobee, an app that makes you a secret shopper, visiting businesses and checking out their service and what's called "product placement."
"If you're going to the store, you could easily spend money there and if you can save money with the app, why not?" said Baumann.
And there's Ibotta, an app that believe it or not, trades you money and rebates for an image of your grocery store receipt.
"All I did was take a picture of my receipt and it puts it into your account and they send a check to you when it gets to be a certain amount of money," said Tara Williams, who has made money with Ibotta in the past.
And there are even apps that pay you to watch movie trailers and take surveys.
"Somedays I'm just on Facebook and instead I could just do this. Money is a good incentive to do anything," said Michael Jenkins, a St. Louis IT expert interested in making extra cash.
According to Ibotta, users have earned a total of $100 million in cash-back rewards. Some of these apps will pay you in points — where it takes a certain amount of points to earn any cash. Others deposit cash directly into your checking or PayPal account.
