It's always a good feeling to make a little cash on the side, especially if you're saving up for a special event. You might be interested to learn that there are ways to legitimately make extra cash just by using your smart phone and apps to get money. Here are three kinds of apps you can sign up for to earn some cash for a rainy day.

User Testing

One of the best ways to make money using your phone is to sign up for a user testing app. These apps are designed to help website owners get an idea of how their site works and is understood by users on their mobile devices.

In general, you can expect to only spend a few minutes on a user test. The test will usually ask you a series of specific questions about a specific website or app to gauge your opinion of it. You'll be asked things like how easy it is to navigate, how responsive the site is, and whether or not you'd be interested in signing up for a service based on its landing page. After answering a few questions, you're done, and the user testing service will send you a payment.

Microtasks

Another easy way to make a little extra money is to sign up for a microtask app. These apps are built around simple, brief little tasks you can perform in order to earn a little money. For example, common tasks include signing up for newsletters, answering surveys, or trying a free trial of a service.

Unlike user testing, microtasks are meant to be completed within mere seconds, rather than minutes or more. As a result, the payout for each task is often lower, but you can expect to be able to complete more of them in a short period of time.

In addition, make sure to determine what options the microtask app you're signing up for offers in payment. Some apps will pay cash via services like Paypal, but others will only reward you with gift cards.

Secret Shopper

Lastly, savvy smartphone users can sign up for secret shopper apps and make extra money while visiting nearby stores. These apps rely upon your phone's GPS and location services to figure out where you are and appoint jobs near to you.

Secret shopping traditionally only referred to hiring people to go into a store to shop and rate their experience, but recently, the experience has expanded. Some secret shopper apps may simply ask you to go into a store and take a photo of a store display and upload it via the app. The company responsible for the display can determine if it's still visible and in good condition, and you get a payout for visiting a store in your local area without spending any money.

Whether you choose one or all of these methods, you can make quite a bit of extra money during your free time.
