As you might guess, mobile development is the process of creating applications that work on mobile devices running iOS or Android OS, and web development is the process of creating websites and web applications that work in web browsers. Both of these fields are always evolving. For example, in the web development space, the trend is moving towards single-page applications(SPAs) and responsive web design, and mobile development is moving beyond just smart phone apps to encompass smart watches and other wearable devices.

However, at the end of the day, app development on any platform comes down to determining user needs, designing and coding software solutions to meet them, and providing ongoing maintenance and user support to ensure your application continues working as intended.

Mobile and web developer careers start with a foundation of coding skills. Some of the most important programming languages to know for mobile and are HTML, CSS, and Javascript, but chances are you’ll want to become familiar with more specialized programming languages like React, which is a Javascript library used for single page or mobile user interface design, and Angular and AngularJS for building dynamic web apps.

Of course, just like other types of software developers, mobile and web developers depend on a lot more than just coding skills. Taking an application through the entire development process requires familiarity with development methodologies, the ability to work with teammates as well as users, and the combination of creativity and logical thinking that characterizes a developer’s problem-solving mindset.

Mobile developers and app developers are in high demand across a wide variety of industries, making this a great career path. According to the Bureau of Labor Statistics, the median salary for software developers building applications specifically was $103,620 in 2018. For a sense of the range of salaries found, the lowest 10% in these roles earned less than $61,660 annually, and the highest 10% earned more than $161,290.

Web developers, meanwhile, receive somewhat lower salaries on average, although this is still a fast-growing occupation. According to the Bureau of Labor Statistics, the median annual salary for web developers was $69,430 as of 2018, with the lowest 10% earning less than $37,930 and the highest 10% earning more than $124,480.

Absolutely. Online courses are a great way to build your mobile and app development skills on a flexible schedule, with a wide range of options to suit your career trajectory and your ultimate goals.

Web developers might want to take programming courses in HTML, CSS, and Javascript to get your coding skills up to par, along with more advanced coursework in topics like web development with React and responsive web design.

On the mobile side, you can take courses on iOS app development and Android app development, along with specialized courses in areas like Objective-C app development, Kotlin, App Inventor, or broader topics like game design, user interface design, and networking and security for apps.

In addition to online courses, Coursera offers short Guided Projects to help you practice and hone your skills.
