How to Find & Hire a Good App Developer in 2021

Whether you’re an entrepreneur with an app idea, a Fortune 500 company, or somewhere in between, you can benefit from hiring a good app developer.

Even if you don’t need a customer-facing app, any business can benefit from internal apps.

Indeed, a report from Fliplet found that businesses get an additional 240 hours of work from each employee who uses mobile enterprise apps. If you paid employees $30 per hour on average, your business would save $7,200 per year per employee from having internal apps.

The problem is that hiring in the tech talent market is extremely competitive. It’s challenging to find app developers who will successfully deliver on your projects.

This article explores how you can find and hire an excellent app developer.

What is an app developer?

The definition of an app developer is a software engineer who develops applications for desktop computers, laptops, mobile devices, and other devices like smartwatches.

App developers are responsible for testing their apps to find and fix as many bugs as possible before either releasing the app or passing it forward to testers.

App developers usually make design decisions when developing their apps to make them easier to use and more functional.

What skills does an app developer need?

There are many aspects to an application, including the platform and device on which it runs, and the type of user who uses it.

Platform-specific skills

An app developer might specialize in developing for a specific platform, such as Windows, Android, macOS, iOS.

App developers commonly use C++ for Windows development because the language can utilize the full performance of a computer. C can also utilize the full performance of hardware running Windows, but development takes longer than with higher-level languages like C++.

App developers can also use other programming languages to create apps for Windows, such as Java, C#, JavaScript, and Python. Each programming language has its pros and cons, with varying development speeds, execution performance, and ease of maintenance.

Java is the official language of Android app development. Kotlin is an alternative to Java. It’s similar to Java but is generally easier to use.

Objective-C and Swift can be used to create apps for any Apple device.

Objective-C is the most popular programming language for creating Apple desktop and laptop apps on macOS.

Swift is the most popular programming language for development on iOS, iPadOS, watchOS, and tvOS. Swift encourages cleaner code compared with Objective-C and includes more safeguards to prevent errors.

Device-specific skills

An app developer might specialize in creating apps for specific types of devices, such as smart TVs or smartwatches.

Different types of devices need apps that account for their unusual properties. For example, a smart TV app has a lot of screen real estate. On the other hand, a smartwatch app needs to use screen space extra efficiently.

Domain-specific skills

App developers can also specialize in development areas, such as office suites or accounting applications.

Developing apps for a particular use case requires knowledge of and experience in that use case. For example, an app developer with accounting training and experience would likely create a better accounting app that accountants will like to use.

How much does it cost to hire an app developer?

The cost of hiring an app developer depends on whether you want to hire a full-time employee, a freelancer, or a development company.

Cost of a full-time app developer

The average salary of an app developer in the US is around $71,000 or $30 per hour and 80% of US app developer salaries are between $50,000 and $100,000, according to PayScale. You can check out the average salary of an app developer in your own country here.

You’ll need to provide full-time app developers with a proper desk setup

Aside from salary, hiring a full-time app developer involves other costs such as equipment, tax and retirement contributions.

Pros of hiring a full-time app developer

  • Employees learn your values and goals, which enables them to make better decisions when building your app.
  • You can communicate with employees more effectively because they take the time to learn how to use your existing communication tools.

Cons of hiring a full-time app developer

  • An individual app developer may be competent in all aspects of app development, but they can’t be a master of every aspect.
  • An employee can be costly to terminate if they don’t perform as expected.
  • You need to provide an employee with equipment and software licenses.
  • You pay employees even when you don’t have suitable work to give them.
  • You need to have a project manager to oversee an employee’s work.

Cost of a freelance app developer

Individual freelancers are usually more expensive per hour than employees because they have more expenses to pay themselves, such as their own equipment, and higher tax contributions.

They charge you more per hour or project, but you only pay them when you need them. This can be a considerable cost saving if you only need an app developer for half a year or less.

$543 is the average cost of a freelancer-completed app project hired from, although tends to attract beginner to intermediate-level talent.

The average hourly rate worldwide for an iOS developer is $81 to $100 and, for a Java or Android developer, is $61 to $80, according to Arc.

Pros of hiring a freelance app developer

  • You only pay a freelancer when you need them.
  • Freelance contracts can be terminated easily if needed.
  • You don’t need to worry about sick pay, taxes, or benefits.
  • You can hire app developers with different skills as needed rather than committing to just one for the long-term.

Cons of hiring a freelance app developer

  • A freelancer may give up on your project in favor of a more profitable one.
  • A freelancer could be working on multiple projects at once, slowing the delivery of your app.
  • If their first language differs from yours, a freelancer could misunderstand your requirements.
  • A freelancer’s programming style and written documentation may not be sufficient for another developer to take over the app.

Cost of a development company

App development companies are usually more expensive to hire than the equivalent number of full-time or freelancers developers.

They are more expensive because they need to pay their own app developers and make a profit for the company.

According to, around half of all app development companies charge more than $5,000 for discovery and more than $10,000 for design. This is before any development, testing, or deployment is done. Ongoing maintenance after deployment costs extra.

A development company could end up being cheaper overall if an employee or freelancer doesn’t successfully deliver your app, forcing you to rehire and redevelop.

Pros of hiring an app development company

  • A development company is guaranteed to finish your app. They have developers of all different specialties, so your project won’t grind to a halt due to inexperience.
  • A development company is more likely to deliver your app on schedule because they can assign more developers to work on it as needed.
  • You don’t need to worry about project management because they manage it in-house.
  • You can tell them what you want the app to achieve and let them worry about the implementation details.

Cons of hiring an app development company

  • App development companies only accept projects worth over a minimum value. According to, 90% of app development companies only accept projects with a value of at least $5,000, and 57% have a $10,000 minimum.
