If you’ve decided to build an iOS app, choosing the right iOS app development company is the core step you need to take. With thousands of app development firms out there, each promising the best results, it’s easy to feel overwhelmed.
The truth is, choosing the wrong development partner can cost you more than just time and money, it can cost you your market opportunity. According to a report by the BCG, 30% of tech development projects fail due to poor communication, unclear requirements, or lack of technical expertise. And with iOS users typically having higher expectations, the margin for error is razor thin.
That’s why asking the right questions before signing any contract is essential. It helps you cut through the noise, avoid common pitfalls, and ensure your app thrives in the App Store.
In this guide, we’ll walk you through the most important questions to ask when hiring an iOS app development company. These questions go beyond the basics and dig deep into areas like technical expertise, design thinking, data security, post-launch support, and more.

A poorly developed app can mean costly delays, rejections from the App Store, unhappy users, and blown budgets. Unfortunately, this happens far too often. That’s why it’s critical to go beyond surface-level qualifications and ask smart, targeted questions before signing any contracts.
Let’s break down the 21 most important questions to ask when hiring an iOS app developer in the USA:
Don’t settle for generic “Yes, we’ve built apps before.” You need proof that they’ve created apps in a similar space, like fintech, healthcare, eCommerce, or gaming. Familiarity with your industry means they’ll understand user behavior, compliance requirements, and design patterns that work.
So, why does it matter? Experienced teams reduce trial-and-error. According to the Project Management Institute, organizations that complete 80% of their client work on time and with great expertise tend to have more successful projects and strategic initiatives.
A strong team should be able to walk you through their development process step-by-step, including how they gather requirements, create wireframes, build MVPs, conduct QA, and handle launch.
Many studies revealed that 52% of projects result in scope creep, which leads to budget overruns and missed deadlines. You need to ensure the company you’re applying to has a structured process.

Apple’s ecosystem is constantly evolving due to new Swift versions, iOS updates, or changing App Store policies. If your development team isn’t proactive, your app could be rejected or become outdated quickly.
Apple rejects around 40% of app submissions each year, primarily due to guideline violations. A knowledgeable team reduces the risk of being rejected or needing urgent rework.
Past performance is a great predictor of future results. You should be able to see real apps that the company has built and evaluate them based on design quality, reviews, responsiveness, and user retention.
Anyone can mock up a beautiful prototype. But pushing a fully functioning app through Apple’s review process requires experience, attention to detail, and technical skills.

A bad interface can lose users in seconds, no matter how well the backend works. iOS users are accustomed to polished, intuitive interfaces, and design plays a crucial role in enhancing usability and accessibility. You need to make sure the team follows Apple’s design guidelines and makes your brand shine.
StatCounter reports that 25% of users worldwide are using the iOS operating system. Skipping compatibility testing can alienate a large chunk of your audience. Your app should run smoothly on the iPhone SE, iPad Pro, and everything in between. Testing for performance, screen adaptation, and battery usage is important for user satisfaction.

Quality Assurance is necessary for a smooth launch. A recent report indicates that 68% of IT projects fail due to poor quality assurance. Without it, negative reviews and app crashes are almost guaranteed. From automated tests to manual regression checks, your team should have a solid QA strategy that catches bugs before your users do.
Apple’s review process can be tough. That’s why understanding how to hire an iOS app development company is important if you want to avoid costly delays. Teams that know the ins and outs of preparing for App Store submission, metadata, screenshots, and privacy policies can drastically cut your time to launch.
Rejection means delays, revisions, and possibly extra development costs. You need a team that has successfully navigated Apple’s review process multiple times before.
Many research claims that the best-performing apps are updated every 2-4 weeks. Without a clear support plan, your app can quickly become obsolete or unstable. The launch step offers regular updates, bug fixes, feature enhancements, and iOS version compatibility.
Lack of ownership clauses is one of the top legal issues in software outsourcing, according to UpCounsel. Without a proper agreement, you may not have legal ownership of the app you paid to build. When you’re outsourcing work, you’re handing over your idea, your vision, and your data. So, if you’re wondering how to choose an iOS app developer, you need to make sure they have clear policies to protect your IP.
Too many businesses start conversations without a clear idea of what an app might cost, and worse, some companies won’t even give you a ballpark figure until you’re present in discussions. That’s a red flag. Here’s the truth: your budget sets the tone for the entire project. Whether you’re building a simple MVP or a full-scale commercial app, you deserve transparency from the start.
According to the recent market figures, most custom mobile app projects cost between $30,000 and $150,000, depending on complexity, features, and design. But that range can stretch further with backend systems, integrations, or custom animations. The best teams won’t avoid the money talk. They’ll help you understand what you’re paying for, what you can scale back, and how to prioritize features within your budget. If you’re interested to learn more about the iOS app development cost, read our detailed guide covering feature-based pricing, developer rates, and hidden expenses.
Before you sign anything, you need to be clear on how and when payments will happen. App development is a multi-phase process, and paying everything upfront or having no structured payment plan is usually a call for misalignment or disputes.
The truth is, clear payment milestones protect both you and the development company. You get peace of mind knowing you’re paying for progress, not promises. They get assurance that their time and resources are being compensated fairly.
A good development company won’t shy away from this conversation. They’ll walk you through how payments are tied to specific deliverables, so you’re always in control, and you always know what you’re paying for.
Every iOS app development company has its own billing method, and understanding how they charge is just as important as the actual cost. You might be surprised how many businesses agree to build an app without fully understanding the pricing model, only to face surprise invoices or stalled progress halfway through.
There’s no “one-size-fits-all” here. The best model depends on your app’s scope, timeline, and the flexibility of your needs. However, a reliable development company should be able to clearly explain its pricing approach and help you determine what makes the most sense for your project. If you’re looking for detailed insights on the iOS app development timeline, check out our blog to understand estimated timeframes, key milestones, and factors.
Before you sign anything, ask about the architecture they use, starting with MVC (Model-View-Controller). Often, developers create tightly coupled systems that are difficult to maintain or scale. MVC separates an app’s data (Model), user interface (View), and business logic (Controller).
Modular architecture, such as MVC, significantly enhances code maintainability and debugging efficiency. A survey found that 71% of developers believe MVC noticeably boosts project quality. A well-structured MVC app makes future changes less risky, testing easier, and onboarding easier for new developers.
Before contracting, you need clarity on what makes this company different. Do they target fintech, healthcare, or AR-driven social media? Do they hold awards or have proprietary technologies?
A company with a sharp USP invests in continuous learning and presents case studies to back their claims. Their USP should align with your market and vision.
You should ask the iOS app development firm how they ensure your app stands out in the saturated market. Over 70% of App Store users discover apps through search, and 65% of installs occur directly after a search.
Advanced ASO, including video previews and optimized screenshots, can increase conversions by 10-30%. Moreover, average conversion rates hover around 25% on iOS and 27% on Android.
Before you sign, clarify the ownership. If you don’t have a source code, you’re locked into their services, potentially overpriced future updates, or vendor abandonment. You need explicit contract language stating you retain full ownership of the code and IP, with deliverables clearly defined.
When you’re discussing with the service provider, ask how they support fundraising. Strong development partners pitch in and help craft MVPs, refine pitch decks, and navigate investor expectations.
Look for teams that’ve worked as startup collaborators and not just coders.
After your app development, probe their monetization insight. Your strategy must align with your business model and user base. It could be freemium subscriptions, one-time purchases, in-app ads, or a combination of these.
The right model can lift revenue 4-5x compared to a one-size-fits-all approach.
You need to establish KPI frameworks if you’re planning to launch the app. Studies have shown that apps lose 70% user base within the first week, and even top apps lose up to 45%.
Success means tracking DAUs, retention rates, crashes, engagement, and end-to-end metrics with tools like Firebase, Mixpanel, or App Analytics.
Once your user base grows or your business expands into new markets, your app needs to grow with it. If you’re supporting thousands of new users, adding new features, integrating third-party services, or launching on additional platforms like iPad or Apple Watch, scalability becomes an important factor.
That’s why you need to work with an iOS development company that builds with the future in mind. A forward-thinking team will utilize a modular architecture, adopt cloud-native infrastructure, and ensure that all code is well-documented, allowing future developers to easily extend it.
Hiring an iOS app development company can be a huge investment, and choosing the wrong partner can cost you money and time. It can even put your app’s security at risk. That’s why it’s essential to identify potential red flags early in the hiring process.
Here are some common warning signs you should never ignore:
If a company can’t give you a clear project plan, timeline, or cost breakdown, that’s a huge warning area. A professional development team should outline:
Be cautious of any firm that guarantees full app delivery in an unusually short timeframe or at a suspiciously low price. Quality iOS apps normally take 3-6 months to develop. Rushing this process often results in:
Reputable iOS app development companies should have a strong portfolio of live apps, case studies, and real client testimonials. If they avoid sharing references or their previous work lacks quality, that’s a sign of inexperience or poor delivery history.
So the common tip for you is to check their apps on the App Store and read actual user reviews. You can also check out rating platforms like G2 and Clutch for more credible references.
Ask yourself questions like:
Strong and consistent communication is essential for the success of any app project, especially when building for the Apple platform. If you’re experiencing delays in email responses, vague answers to your questions, or difficulty identifying a point of contact, consider that a serious red flag.
Poor communication often leads to:
The code that powers your iOS app is your intellectual property (IP). If the development company doesn’t hand over the source code or refuses to include ownership rights in your contract, walk away.
Some developers try to retain code ownership so they can reuse components or lock clients into ongoing maintenance agreements. This can cause major problems if you ever want to:
iOS is an evolving ecosystem. Apple introduces new APIs, tools, and design guidelines every year during WWDC (Worldwide Developers Conference). Your app should be built using modern best practices to ensure performance, security, and compatibility with current and future devices.

This process begins with evaluating the company’s technical expertise, past projects, and industry credibility. Look for a team that specializes in Apple technologies, such as Swift, SwiftUI, and Xcode, and has a proven track record of launching successful apps on the App Store. Whether you’re partnering with a full-service agency or looking for an iOS app developer for hire, make sure they have solid case studies, positive client reviews, and a professional approach to handle technicalities.
The ideal company should also offer post-launch support, ensure App Store compliance, and be transparent about their communication methods, pricing structure, and delivery timeline. Most importantly, they should take the time to understand your vision and offer strategic input to bring your app to life.
Hiring an iOS app developer is about finding someone who can contribute meaningfully to your product’s success. Begin by defining the scope of your app and identifying the necessary skills (e.g., Swift, UIKit, Core Data). Then, assess candidates based on their technical proficiency, knowledge of Apple’s Human Interface Guidelines, and experience with submitting apps to the App Store.
Ask for live app examples, run technical interviews or small test tasks, and evaluate their ability to collaborate within teams. If you’re hiring freelance talent or partnering with an agency, prioritize developers who can deliver clean, scalable, and well-documented code.
The app development process usually follows five key phases:
Before moving into app design, asking the right questions helps align expectations and ensure a user-centered approach. Here are five essential ones:
These questions lay the foundation for a design that is functional, aesthetically pleasing, and personalized to your users’ requirements.
When starting your iOS app development process, you first need to find a development company with proven experience in Apple technologies. If you’re hiring an iOS app developer, focus on both their technical skills and communication abilities, and always ask for real examples of apps they’ve launched. Here are the things you need to consider:
iOS developers normally charge between $80 and $150 per hour, depending on their experience, location, and the scope of work. Freelance developers may offer slightly lower rates, starting around $60/hour, but top-tier iOS specialists or developers from established agencies can charge upward of $150-$120/hour for complex projects.
For full projects, expect to pay between $40,000 and $ 100,000 for a mid-range iOS app, while enterprise-level apps with advanced functionality (such as AI, real-time syncing, or AR features) can cost $150,000 or more.
The timeline of developing a fully functional iOS app ranges from 3 to 6 months, depending on complexity, team size, and approval cycles. A streamlined MVP (Minimum Viable Product) can be launched in about 8 to 12 weeks, whereas a more complex app involving custom APIs, third-party integrations, or secure user data handling may take 6+ months.
Here’s how the timeline generally breaks down:
