13 Questions to Ask When Hiring a Mobile App Developer

Key Takeaways

  • Hiring the right mobile app developer starts with asking the right questions, not just comparing prices. 
  • A strong development partner should offer transparency around experience, process, timelines, and costs.
  • Communication, testing, and post-launch support are as critical as the development itself.
  • Clear ownership of source code and intellectual property protects your long-term business interests.
  • Scalability and security should be planned from the beginning, not added later.
  • The best mobile apps are built by teams that understand both technology and business goals.

Building a mobile app is an investment in your brand’s future. The right development partner can turn your idea into a user-friendly, scalable product. The wrong one can eat up your budget and leave you with an app that doesn’t work properly. 

One retailer cut churn by 40% after switching to a team that prioritized user engagement and technical excellence, illustrating how pivotal the right partnership can be.

Imagine you’re on your first Zoom call with a prospective mobile app developer.Use the following twelve questions to guide the conversation, ensuring you uncover crucial insights about their technical competence, communication style, professionalism, and alignment with your goals. Skip these and risk a six-figure rewrite, plus the loss of valuable time and resources. Ensuring you choose the right partner can save you from potential pitfalls down the road.

1. Can you show examples of your past work?

A proven track record is one of the best indicators of reliability. Ask potential developers to walk you through apps they have built recently, ideally those currently live on app stores. A strong portfolio signals professionalism and shows that they can deliver high-quality apps that meet user expectations. 

2. Who are your current and previous clients?

Beyond portfolio pieces, find out which businesses or individuals they have worked with. A diverse client base and the willingness to provide references suggest trustworthiness. Developers may need to omit projects covered by non-disclosure agreements, but they should be comfortable showcasing non-confidential clients to demonstrate credibility.

3. What are your core services and expertise?

Mobile development involves more than writing code. Determine whether the team offers user interface design, backend development, quality assurance, and app store submission. Clarifying their core competencies ensures they can handle your project end to end. 

Additionally, ask them to whiteboard the data flow in five minutes. This request can surface their design thinking and reveal their depth of expertise early in the conversation.

4. Which platforms and devices do you build for?

Some apps are best built natively (with separate codebases for Android and iOS), while others can be cross-platform. Native development often provides better performance and design fidelity, but it can be more costly to maintain. 

Cross-platform solutions like React Native offer cost-effective development and maintenance but may come with performance trade-offs. Ask which technologies the developer prefers and whether they test on actual devices. This helps you understand their commitment to creating polished experiences across different smartphones. 

To further guide your decision, invite discussions on the total cost of ownership for both paths by asking, ‘Show me the total cost of ownership for both React Native and Swift/Kotlin.’ This will ensure you choose the best approach for your app’s performance, cost-effectiveness, and long-term maintenance.

5. What unique features will you implement?

Stand-out features often determine an app’s success. Discuss any innovative functionality they propose, such as offline capabilities, location-aware services, or AR/VR, and how these align with your goals. 

It’s crucial to delve into the rationale behind each proposed feature. Ask the developer, ‘What user data or experiments suggest this AR idea will move our metric?’ By seeking evidence-based insights, you ensure that feature implementation is driven by real user needs and potential impact on your goals. Developers should be ready to articulate how they will handle feature implementation and user engagement.

6. How will we communicate during the project?

Clear communication prevents misunderstandings. Agree on tools and meeting schedules up front, whether through email, Slack, video calls, or weekly progress reports. Establishing a communication plan early ensures you’re always aligned on scope, timelines, and potential roadblocks.

7. Do you have a developer account on major app stores?

Publishing to Apple’s App Store or Google Play requires a developer account. Confirm that your developer has the necessary accounts and experience submitting apps. A developer without one may signal a lack of experience with the app-store submission and review process.

8. How do you determine the project cost?

Ask for a transparent breakdown of how costs are calculated. Factors include feature complexity, platform choice, and expected development hours. Many developers work with milestones, requesting payments as each phase is completed. Transparent pricing helps prevent surprises later.

9. Who will test the app before launch?

Quality assurance is crucial. Some developers handle internal testing, while others expect clients to arrange for a separate QA team. Discuss how bugs will be reported and fixed, how beta testers will be recruited, and whether there is a plan for updates and bug fixes prior to submission.

10. Do you provide maintenance and support?

After launch, mobile platforms frequently update their operating systems, and new devices enter the market. Ask whether the developer offers ongoing maintenance, bug fixes and feature updates, and if so, what it will cost. Support can be the difference between an app that fails and one that thrives.

11. Have you earned any awards or recognition?

Awards or industry recognition aren’t required, but they can offer extra assurance. They show that the developer or agency has been acknowledged by peers or associations, indicating a commitment to quality.

12. Do you offer app marketing or App Store Optimization (ASO)?

Building an app is only part of the journey; getting it discovered is another. Some developers also provide ASO or digital marketing services to help apps rank higher in search results. If this aligns with your strategy, ask about their approach and pricing 

Additionally, inquire about how their keyword strategy connects to broader goals, such as user retention, not just installs. You might ask, “Which ASO tactic has improved day-7 retention in your past projects?” This helps ensure that your efforts translate into sustained engagement.

13. How will you handle scalability, security, and future growth?

An app should not just work on day one. It should be able to grow with your business. Ask the developer how they plan to design the app to handle increased users, new features, and higher data loads over time. This includes questions around backend architecture, API scalability, data security, and compliance with platform guidelines.

A strong development partner will think beyond the initial release and help you plan for long-term performance, updates, and security protection. This forward-looking approach often separates experienced teams from short-term builders.
