Have you ever taken a deep breath after you read the news about the inhumane and atrocious conditions in which children in poor countries live?

Have you ever wished with all your heart to be able to satiate other people’s hunger and mend their emotional and physical scars?

Have you ever wanted to change the world but have little time and money to do so?

If your answer to at least one of these questions is yes, I’ve got something for you.

You can make an impact through these three free charity apps. Here is the list:

1. Share The Meal

“With a tap on your smartphone, you can “share the meal” with a child in need. It costs only US $ 0.50 to feed one child for a day.”

Share The Meal is the world’s first mobile application developed to fight against global hunger. This initiative was created by the United Nations World Food Programme (WFP) and has been impacting hundreds of lives.

If you desire to share a meal right now, you can choose between feeding a child for one day ($0.50), for one week ($3.50), for one month ($15.00), for three months ($45.00), or for a year ($182.50). On the other hand, if you are devoted to ending hunger and have the financial resources to take aid further, then you can click on the “Give Monthly” button.

In addition, you are able to choose between helping Rohingya children, alleviating Syrian children refugees’ pain or supporting children who are fighting famine in Nigeria.

Log in. Tap. Done.

It’s that easy.

2. Charity Miles

“Move with purpose. Earn money for charity.”

What if I told you that every single time that you walk to your 9 a.m. class, grab a coffee with a friend, go to the gym or walk your neighbor’s cute dog, you can actually save a life?

In another time in history, people would think I’d gone crazy.

Truth is, we live in the 21st century, and this, my friend, is entirely possible.

How?

Charity Miles is a socially-driven, for-profit company that created an app that enables users to earn money for a cause when they move.

Turn your phone on. Log in. Choose from 1 of their 37 charity partners like Operation Smile, Save the Children, Pencils of Promise or The American Diabetes Association and get moving.

3. Donate a Photo

You take a photo, we make it look good.

Wait… WHAT?

Yup, you read that right. Something as simple as taking a picture can help individuals all around the globe.

This application is strikingly simple to use.

First, explore the cause categories. The categories are women’s and children’s health, healthy families, health workforce, environmental health, global disease challenges, essential surgery, education and quality, and emergency relief.

Second, choose a nonprofit.

Then, shoot a picture.

Share it.

For every photo you share through this app, Johnson & Johnson donates $1.00 to a nonprofit of your choice. (You can donate one photo per day.)

If you are the type of person who wants to make a difference,

You are welcome.
