OVERVIEW
What Is an Application Developer?
Application developers—often called “app developers”—design applications for use across mobile devices. They also build applications for mobile and desktop spaces, including professional design and office productivity programs.
Though app developers may share responsibilities with software developers and programmers, they are uniquely trained to create high-quality applications specifically for devices like smartphones and tablets.
Most app developers earn a bachelor’s degree in addition to one or more industry certifications. Some employers prefer to hire app developers who have a few years of experience in programming, software development, or a similar IT field.
What Are the Different Types of App Developers?
App developers typically specialize based on the platforms and technologies they work with. While many developers expand their skill sets over time, most begin by focusing on a primary area before branching out over the course of their careers.
- Mobile app developers: Mobile app developers build apps specifically for smartphones and tablets. iOS developers often use the Swift or Objective-C programming languages to create apps for Apple devices, while Android developers rely on Kotlin or Java for building apps. Native mobile developers focus on platform-specific performance, design guidelines, and user experiences.
- Cross-platform app developers: Cross-platform app developers use frameworks like React Native or Flutter to make apps that function on multiple operating systems from a single code base. This way, companies can launch apps faster and maintain them more efficiently, making cross-platform development particularly popular for small organizations and startups.
- Web application developers: Web app developers create browser-based, responsive applications using HTML, CSS, and JavaScript frameworks. Unlike native mobile apps, web apps run in a browser and are accessible across devices without installation. This makes web apps ideal for tools, dashboards, content-driven platforms, and more.
RESPONSIBILITIES
What Does an Application Developer Do?
Whether they’re creating new applications or updating existing apps according to new security protocols, app developers work to provide the best possible mobile experience for users.
App developers often perform the following tasks:
- Creating new apps for mobile users.
- Tailoring app details to ensure compatibility across both mobile and desktop hardware.
- Integrating mobile apps with an organization’s existing network.
- Implementing AI tools in the app development process.
- Troubleshooting issues with app operation and performance.
- Optimizing apps to reflect changing business practices and user preferences.
- Ensuring compliance within local, state, and federal app parameters.
- Training app developers in best practices.
- Communicating with other IT professionals and stakeholders.
These and other responsibilities keep app developers busy as they work to build and refine applications for users to enjoy.
Where Do App Developers Work?
App developers work in a wide range of environments, depending on the products they build and the needs of their employers. Some application developers work as independent contractors or freelancers, partnering with clients to design and build custom apps. Others are full-time employees embedded within an organization’s IT, engineering, or product teams, collaborating closely with designers, marketers, and business stakeholders.
App developers commonly find employment in industries such as:
- Tech research and development firms
- Private businesses and enterprise organizations
- Nonprofit and mission-driven organizations
- Healthcare providers and health tech companies
- IT service providers and consulting firms
- Mobile device manufacturers and tech companies
- Cellular service providers and telecommunications companies
Because mobile and web apps are often key drivers of user engagement and brand growth, app development is sometimes closely linked to marketing and digital strategy. As a result, some app developers work for marketing agencies, advertising firms, or brand consulting companies, where apps support customer acquisition, engagement, and retention efforts.
EDUCATION & BEST DEGREES
What Education Does an Application Developer Need?
Education plays an important role in preparing for a career in app development. Most app developers begin with a bachelor’s degree, which helps build foundational skills in programming, data management, systems design, and software development best practices.
Many aspiring app developers choose a bachelor’s degree in software engineering, where they gain experience with coding languages, application architecture, and development workflows. A bachelor’s degree in cloud engineering can also be a strong option, especially for developers interested in building apps that rely on cloud-based backends, application programming interfaces (APIs), and scalable infrastructure.
Regardless of the undergraduate path, bachelor’s degree programs emphasize hands-on development, problem-solving, and real-world application design, which are all skills that employers consistently look for in prospective app developers.
How to Become an App Developer
App development careers typically follow a progression as skills and experience grow:
- Entry-Level (0–2 years):
Junior Developer, Associate Developer
Entry-level developers focus on learning development tools, writing and testing code, fixing bugs, and supporting senior developers.
Typical salary range: $65,000–$90,000 - Mid-Level (2–5 years):
App Developer, Mobile App Developer
Developers at this stage take ownership of features, collaborate more closely with product teams, and contribute to architecture decisions.
Typical salary range: $100,000–$115,000 - Senior-Level (5+ years):
Senior Developer, Lead Developer, Team Lead, Mobile Architect
Senior developers design systems, mentor others, and guide technical direction.
Typical salary range: $110,000–$130,000+ - Leadership Paths:
Engineering Manager, Solutions Architect, Director of Mobile Development, CTO
Developers may choose to remain technical or move into people leadership and strategy roles, depending on their interests.
App Developer Certifications to Consider
Certifications aren’t always required, but they can help early-career developers stand out, especially when combined with hands-on project experience.
- Platform-Specific Certifications:
- Associate Android Developer
- Apple development credentials (less formalized, but platform knowledge is highly valued)
- Cloud Platform Certifications:
- AWS Certified Developer – Associate
- Microsoft Azure Developer Associate
- Programming language Certifications:
- Oracle Certified Professional (Java)
WGU also offers focused credentials like the ServiceNow Application Developer certificate, which prepares students to build and customize enterprise applications.
While certifications can strengthen a résumé, employers may prioritize real-world projects and working apps. The strongest candidates combine both.
