iPhone App Development Company Hiring Guide

What is an iPhone app development company?

An iPhone app development company specializes in building high-quality, custom iOS applications for Apple devices, including iPhones, iPads, Apple Watch, and Apple TV. These companies leverage tools and programming languages such as Swift, Objective-C, and Xcode to create seamless native mobile experiences. 

An iPhone app development company can develop the following:  

  • Native iOS apps: Designed exclusively for iOS, offering optimal performance and user experience. Swift enables faster, more efficient development compared to Android. 
  • Hybrid apps: Built to run on multiple platforms, offering broader reach at the cost of native optimization and depth of features.

As Apple's product lineup diversifies, iOS app developers deliver apps for iPhones, iPads, Apple Watch, and Apple TV. 

What do iPhone app development companies do?

iPhone app development companies use the latest technologies to build high-performing, secure iOS applications. They deploy the product in production and submit it to the App Store, ensuring it meets Apple's guidelines and aligns with user preferences for look and feel, ease of use, and performance. 

An iPhone app development company also helps with: 

  • Concept ideation and strategic planning
  • UI/UX design tailored for iOS
  • Native and hybrid app development
  • Backend setup and API integration
  • QA testing and debugging
  • App Store deployment and compliance
  • Ongoing support and maintenance

How much does it cost to develop an app for iOS?

Developing an app for iOS costs $10,000 to over $500,000. On average, businesses spend around $50,000 to launch a reliable iOS app.  

Factors that impact these costs are: 

  • App's level of complexity 
  • Backend configuration and administration 
  • The company's experience and team size 
  • Time needed to develop the app from scratch 

The following table breaks the total cost estimates down based on complexity and timeframe:

App complexity Cost Timeframe 
Simple app $10,000 to $60,000 2 to 4 months 
Medium-complexity app $60,000 to $100,000 4 to 6 months 
Complex app $100,000 to $500,000+ 9+ months 

[Source: SPD Load]

iPhone app development companies typically charge on an hourly basis. They calculate development costs by multiplying the number of hours required to develop each feature by the hourly rate for the development team. 

Here are the average hourly rates for the individual roles in an iPhone developer team:

RoleAverage hourly rate 
iOS app developer $50 to $100 
UI/UX designer $20 to $50 
Project manager $50 to $150 
QA engineer $30 to $80 

[Source: InfoStride

How long does it take to make an iPhone app?

Building an iPhone app can take three to nine months, depending on its complexity and features. For a clearer perspective, here are estimated timeframes for iOS app development:

 Simple apps Medium-complexity apps Complex apps 
Requirement analysis and planning 1-2 weeks 2-3 weeks 3-4 weeks 
Wireframing 1-2 weeks 2-3 weeks 3-5 weeks 
UI/UX design 2-3 weeks 5-6 weeks 9-10 weeks 
Development 6-7 weeks 14-15 weeks 20-22 weeks 
QA and deployment 1 week 2 weeks 3 weeks 
Total 11-15 weeks / 2-4 months 25-29 weeks / 5-7 months 32-44 weeks / 7-10 months 

Why should I hire trustworthy iOS app developers?

These are the top three reasons to hire an iPhone app development company: 

1. Keep sensitive data secure 

Partnering with a professional iPhone app development company will ensure the highest level of security for your app and keep your data safe from external threats. 

2. Enhance customer experience 

iOS app developers can help increase user engagement and retention by: 

  • Using push notifications properly
  • Running retargeted advertisements
  • Sending in-app personalized messages
  • Leveraging machine learning (ML) for recommendations

3. Generate higher app revenue 

iPhone applications drive a high return on investment (ROI) from in-app purchases, subscriptions, and premium games. Professional iOS development leverages the latest trends and technologies to deliver the best user experience. 

Success story

Fullestop developed a multilingual iOS app featuring real-time tracking, secure payments, and an intuitive UI.  It also developed the app in English and Arabic to eliminate language barriers. The app scaled to 5,000+ orders post-launch and projected 30,000+ in its first month.

How do I hire a trusted iPhone app developer?

Follow these steps when hiring a reliable iPhone app developer: 

  1. Define your requirements and assess your budget. This is also where you decide on whether you need a native or a hybrid application. 
  2. Research and compare the top iOS app development companies.
  3. Read and verify client reviews, ratings, and recommendations. You can also ask your network about the companies you've researched. 
  4. Look at their portfolios and check for projects within your domain. Evaluate the stages of their design process: wireframing, concepts, storyboards, prototyping, and others. 
  5. Ask about their approach to UI/UX design. Examine their development process, methodologies, tools, iOS software development kit (SDK), and proficiency in Swift and Objective-C programming languages, frameworks, and databases. 
  6. Check whether they provide a full cycle of iOS app development services, including research and market analysis, API development and integration, testing, and post-release support and maintenance. 
  7. Select up to five candidates from your list. Send them a request for proposal (RFP) and ask for price estimates with a breakdown. 
  8. Receive and review proposals. Arrange interviews to get to know the teams that developed the proposals. 
  9. Decide based on your evaluations, and examine the contract before entering into an agreement. 

DesignRush can help you in your search for the ideal iPhone app development company for free. Simply head to our Marketplace to share your project details. We'll connect you with up to five of the best candidates from our directory.

  1. How many apps have you developed? 
  2. Do you have a track record of working with clients or a portfolio of apps that can be aligned with our needs and ideas?

  4. What's your preferred development methodology? 
  5. What's your experience with payment integrations?

  3. How do you guarantee that your applications are accessible and optimized for scrolling performance? 
  4. What's your process for QA testing, debugging, and profiling codes? How do you test the application's impact on device performance? 
  5. How do you secure private user data on a device?

The Project
