Bored waiting for an appointment, bus or for traffic to clear up? You could be making cash right now. That’s right, you just need the right money apps on your phone and you can turn any unpleasant wait into a business opportunity.

Why would an app give you money? Isn’t that just a scam? No, the truth is that there are a lot of things that marketers need from you that they can’t get people to do for free—things like filling out surveys, testing out new web stores and measuring how much the public knows about certain brands, lines or influencers.

If you’d like to be one of the people who gets paid to provide this information, here are some of the best apps for you.

Swagbucks

Swagbucks is one of the most popular money-making apps out there and has paid out hundreds of millions since it first appeared in app marketplaces. The app tracks you as you do things like shop online or use other apps, and gives you cash and gift cards based on your activity. You can take surveys, watch videos, or even just browse the web.

SwagIQ

SwagIQ is another app that’s related to Swagbucks, but unlike its namesake, it is focused entirely on trivia. You’re given time tests that are used to track your knowledge of events, entertainers, and brands. If you’re one of the top-performer, you can collect impressively high cash prizes. Final winners can collect as much as $500 a game.

HQ

HQ is another trivia app that pays out in cash. In fact, it was one of the first and biggest pay-trivia apps and the one that SwagIQ was based on. Players compete to be the last one standing against competitors by answering trivia questions, with eliminations for wrong answers. The final winner can win as much as $5,000!

InboxDollars

InboxDollars is one of Swagbucks fiercest competitors, and there are many people who are happy to members of both platforms. Surveys are the main activity on the app, but you can also collect your points by reading prepared emails or watching videos. They are known for paying out reliably.

Survey Junkie

Survey Junkie is widely trusted by its user base of tens of millions. It developed a lot of loyalty because of how reliably it pays out. It’s completely survey-based. You get points for each survey you fill out, and when you have enough points, you get to trade them in for PayPal cash. Sometimes, you can get even greater rewards by agreeing to gift cards.

MyPoints

MyPoints isn’t as large as some of the other survey apps, but it has been around and paying out since the mid-90s. Like Swagbucks, it gives you the option of completing many different kinds of tasks. When you’ve collected enough points from surveys, browsing of shopping, you can cash out on Paypal, or claim gifts cards and even airline miles.

Toluna Opinions

Toluna is another huge competitor that goes toe-to-toe with Swagbucks by offering a great experience. It’s focused on surveys and has long-term relationships with some of the world’s biggest brands. Some users find it easier to find more lucrative surveys on this app because of these relationships.

Bananatic

Bananatic offers you a few different options that you won’t see in other money apps. Instead of filling out surveys, you can do fun things like test new games or create your own written or video content to review the latest games and apps. You can also do much easier tasks like letting the app follow you through your shopping habits. If you love gaming, you can collect skins and other in-game rewards through this app.

Shopkick

If you love shopping and want to make your money on the go, Shopkick may be the perfect money app for you. This one rewards you with points for entering stores, scanning products or purchasing stuff you already need. You can fill out surveys related to your most recent visit about what you noticed in displays or how easily you found what you were looking for.

You don’t even have to put on your walking shoes. You can get the same rewards by browsing online stores.
