What does a Native app developer do?
A native app developer builds mobile applications specifically for one operating system, such as iOS or Android, using the official tools and programming languages provided by that platform. This approach allows the software to access device hardware like cameras and GPS sensors with high performance and responsiveness. The developer writes code that compiles directly into machine instructions for the target device rather than running through a web browser or intermediate layer. They manage the entire lifecycle from initial architecture design to final submission to the Apple App Store or Google Play Store.
- Writes platform-specific code using Swift for Apple devices or Kotlin and Java for Android systems within integrated development environments like Xcode or Android Studio. This work involves creating user interface components that follow strict human interface guidelines to ensure the app feels familiar to users of that specific operating system. The developer structures the application logic to separate data handling from visual elements, which makes the code easier to test and maintain over time.
- Builds and runs the application repeatedly on simulators and physical devices to identify errors in the interface or logic before they reach end users. They use debugging tools included in the platform SDK to trace memory usage and fix crashes that occur during complex user interactions. This iterative process requires compiling the source code often to verify that new features integrate correctly with existing functionality without breaking previous work.
- Creates automated tests that verify individual functions and broader user workflows to confirm the app behaves as expected under various conditions. These tests run within the platform testing framework to catch regressions early in the development cycle and reduce the need for manual checking later. The developer documents these test cases to help other team members understand how the application should respond to different inputs and edge cases.
- Prepares release builds by configuring signing certificates and provisioning profiles required by the platform vendors to distribute the software securely. They generate the final binary packages and submit them through the respective developer consoles for review and approval by the store teams. This step also involves updating app metadata and screenshots to accurately represent the current version of the software to potential downloaders.
How to hire a Native app developer on Upwork
Step 1: Post a job
Define the target platform and required toolchain in your job description. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise listing. Describe your needs in a few sentences and Uma drafts a job post for the role. You can write a new post, update a saved draft, or reuse an existing post.
- Specify whether the project requires iOS development with Xcode and Swift or Android development with Android Studio and the Android SDK.
- List deliverables such as working app builds for simulators, automated unit tests, and release-ready packages prepared for signing.
- State the expected hourly rate within the typical range of $11-$20/hr to attract qualified candidates familiar with native mobile architectures.
Step 2: Evaluate candidates
Review portfolios for evidence of platform-specific expertise and clean code architecture. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit quickly.
- Look for published apps in the Apple App Store or Google Play Store that demonstrate smooth performance and adherence to platform design guidelines.
- Check for experience with distribution tooling like TestFlight to verify the candidate knows how to manage beta testing and release workflows.
- Examine code samples for maintainable component boundaries and proper separation of responsibilities to ensure long-term testability.
Step 3: Interview your top choices
Discuss technical approaches to common mobile development challenges during the interview. Schedule and conduct these conversations within Upwork Messages with an immediate transcript and summary after each one.
- Ask how they handle build errors in the IDE and issue navigator to gauge their debugging efficiency and problem-solving process.
- Request examples of automated testing strategies they have implemented to verify app quality before submission to app stores.
- Discuss their approach to managing app resources like platform-specific images and strings outside of the main codebase.
Step 4: Agree on scope and begin work
Finalize milestones for app features, testing phases, and store submission. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Set clear milestones for delivering working builds on connected devices and completing specific automated test suites.
- Define the process for preparing release builds with required signing assets for final distribution via platform channels.
- Establish a schedule for regular code reviews to maintain architectural integrity and reduce coupling between app components.
