Today, I’m sharing five legit mobile apps that you can download for free and start earning with immediately.

I’ve done the research for you—these apps are not scams, and thousands of users are already earning real money with them.
Make sure you read until the end, because App #5 is the easiest and fastest way to earn, in my opinion.

If this is your first time visiting my blog, welcome! I write about online marketing and online income opportunities. If you enjoy this kind of content, feel free to bookmark the site so you don’t miss new posts.

Before we start, I highly recommend creating a PayPal account. Most of these apps pay via PayPal, and it only takes a few minutes to sign up on PayPal’s official website.

Now, let’s look at the five best apps to make money using your phone.

  1. Userfeel

Userfeel pays you to test websites and apps by sharing your honest feedback.
You’ll browse a site or try using an app, point out what’s good or bad about it, and give recommendations.

Each task usually takes 10–20 minutes, and you earn $10 per test.

Here’s how it works:

.When you sign up, Userfeel gives you a free qualification test.

.You need to record your screen and your voice as you walk through the test tasks.

Based on your performance, Userfeel will decide how many paid tests you receive.

Do well → You get more tasks.

Do poorly → You get fewer.

It’s simple, straightforward, and one of the best-paying usability testing apps available.

  1. Rewardable

Rewardable offers multiple ways to earn money—whether you’re at home or out shopping.

At home, you can earn by:

.Watching short videos

.Completing surveys

.Entering daily sweepstakes

In stores, you can earn by:

.Reviewing products

.Completing small tasks

.Answering quick quizzes

Rewardable has already paid out over $5 million to its users.
As you complete more tasks, your account level increases, unlocking better opportunities.

The app has been featured in major media outlets such as ABC, NBC, and Business Insider, and boasts thousands of 5-star reviews—so you can trust it’s legitimate.

  1. Foap

Foap is perfect for anyone who loves photography. It offers two main ways to earn money:

Method 1: Sell Your Photos

You can upload your photos directly to the platform.
Each time someone purchases one of your photos, you earn $5 (Foap takes a 50% commission from the $10 price).

If you’re a photographer, uploading a large collection of photos can turn into stable passive income.

Method 2: Join Missions

Foap also hosts brand “missions.”
Big companies—like Coca-Cola—often need creative photos for marketing campaigns on Instagram or Facebook.

They post mission details asking users to take themed photos in specific locations or scenarios.

Rewards usually range from $700 to several thousand dollars, depending on the difficulty and brand requirements.

  1. Google Opinion Rewards

Google Opinion Rewards is one of the most trusted survey apps available.

It has over 1.6 million reviews and an almost 5-star rating.

Since it’s a Google product, you can use it with complete confidence.
The app pays you for completing short surveys—many of which involve reviewing ads, because Google wants to know which ads perform better.

This feedback helps advertisers improve their campaigns and helps Google refine its ad system.

Surveys are short, quick, and very easy to complete.

  1. Field Agent

Field Agent is the app I think is the easiest way to earn real money.

Here’s how it works:

.Enter your location

.A map shows available tasks near you

.Complete small jobs in nearby stores to earn cash

Tasks vary widely. Many involve taking photos of products in a store—for example, checking shelf placement or photographing packaging.

Why do companies pay for this?
They want to make sure their products are displayed correctly and visible to customers.

Field Agent pays $3–$12 per task, and each task usually takes 10–15 minutes.

This means you can easily earn around $50 per hour if you pick multiple tasks close to each other.

The next time you’re grocery shopping, open the app and look for tasks around you. It’s one of the simplest ways to make extra money while running errands.
