iPhone App Development Company Hiring Guide

What is an iPhone app development company?

An iPhone app development company has the expertise in programming languages and tools necessary to design, develop, and launch high-quality custom iOS applications for mobile Apple hardware, including iPhones and iPads. It exclusively specializes in the iOS technology stack, namely, Objective-C, C, C++, and Swift. 

An iPhone app development company can develop the following:  

  • Native iOS apps: These are made to run on iOS devices only. As such, they are built with all the operating specifics of the platform and generally work more smoothly. Their development is faster and even less costly than for Android, thanks to the Swift programming language. 
  • Hybrid apps: These are designed for multiple operating systems and, with twice the audience size, are usually less lush with features and functionalities. 

As Apple’s array of products continuously diversifies, iOS app developers are expected to deliver products not only for new versions of iPhones and iPads but also for devices such as Apple Watch and Apple TV. 

What do iPhone app development companies do?

iPhone app development companies implement the best technologies to create high-performing and secure iOS applications. They deploy the product in the environment as well as release and submit it to the App Store, ensuring it meets Apple's guidelines and the user’s preferences in terms of look and feel, ease of use, and performance. 

An iPhone app development company also helps with: 

  • Conceptualizing and planning the idea with the client 
  • Enhancing user experience (UX) on iOS 
  • Rolling out new app versions 
  • QA testing 
  • Ongoing technical support and maintenance 
  • And more 

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 the: 

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

Here’s a table that breaks the total cost estimates down based on complexity and timeframe:

App complexity Cost Timeframe 
Simple app $10,000 to $60,000 2-4 months 
Medium-complexity app $60,000 to $100,000 4-6 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 the development costs by multiplying the number of hours required to develop each feature with the hourly rate of the development team members. 

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

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 
  • And more 

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 incorporates the latest trends and technologies for the best user experience. 

Emphasizing these reasons is a case study by iOS developer Fullestop on its work for Cravez, a food delivery app. Fullestop incorporated simple search and order confirmation functions, a real-time tracker, and multiple payment options. It also developed the app in English and Arabic to eliminate language barriers. 

Shortly after release, the iOS application was managing 30 food outlets and 5,000+ orders. It was also projected to list 100 more restaurants and handle 30,000+ orders 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 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 if they provide a full cycle of iOS app development services, which should include 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 who developed the proposals. 
  9. Decide based on your evaluations, and examine the contract before entering into an agreement.
