Almost every tech geek would have dreamed of creating an app at some point in their life – one that is aesthetically and functionally pleasing. And if you have an excellent idea for an app, it is the best thing to do because mobile apps are expected to generate a staggering amount of US$693 billion by 2021.

However, what stops most of us from creating apps is the lack of expertise. Of course, you can always outsource app development, but it will be costly. If you are an entrepreneur on a solo quest to develop an app, or a newbie planning to become a mobile app developer, you need to learn app development from scratch.

This article is all about learning app development, and we will introduce you to 20 free app development courses to kickstart your career or fuel your passion. Before that, let’s talk about a question that raises eyebrows all the time.

How Long Does It Take to Learn App Development?

Although learning app development is a continuous process, fair estimates can range from a couple of hours to even six months. The disparity between these figures is primarily because of the nature and complexity of each app development course.

For instance, if you want to learn to develop a basic gallery app, it may take only a few hours to do so. But learning to create complex apps that incorporate location services, graphics, and advanced functionalities may take months.

If you are a newbie in app development, check out our guide on how to become a mobile app developer that clearly defines the steps you will need to take to become a successful developer.

Where Can I Learn App Development for Free?

Although self-learning from YouTube tutorials and developer forums is equally effective to learn app development, enrolling into an app development course will bring more structure to your learning experience. 

We have compiled 20 best courses that allow you to learn app development for free.
