How to Hire App Developers


It has been estimated that there is somewhere in the region of 20 million software developers in the world today, a figure that is more than double the number of 2014.

Around 50% of these developers are estimated to be offering mobile app development services in either a full-time or freelance capacity.

For companies and individuals who desire to create world-class mobile applications, finding top app developers in this huge pool of talent can be an enormous challenge that is fraught with danger.

Whether you are a small startup company that is looking to build its first app, an entrepreneur seeking to expand into the lucrative app market, a project and product manager, a CEO, or CTO, knowing what to look for is key. Understanding how to sieve out the best from the rest is crucial to ensuring that your project is completed on time and to a high specification, and without it being infested with bugs.

In the spirit of Henry Ford’s statement that “working together is success”, we decided to share our expertise by putting together this informed guide on how to find app developers who will help you make your dreams a reality.

Why Mobile Apps Are the Key to Success?

According to the latest estimates, the number of smartphone users in the world is expected to reach 3.5 billion in 2025.

This means that roughly a third of the world’s population will use an iPhone or Android phone in order to browse the internet, shop in the app store or online, play games, watch videos, listen to music, etc. Things that only a decade ago seemed unimaginable to do with just one device.

But, why do you need an iOS or Android mobile app if your website is already optimized for mobile?

Well, you’re wrong if you believe that simply having a mobile-optimized site is enough for today’s tech-savvy users, who are practically glued to their smartphones every minute of the day.

Today, not only do big brands such as AliExpress, Ikea, or Starbucks rely on dedicated mobile apps as an important element of their online marketing strategies, but businesses of all sizes do too.

Small and midsize businesses can greatly benefit from tapping into the mobile app frenzy.

Here’s why:

  • Improving brand visibility and awareness. Given that Americans, on average, spend more than two hours a day using their smartphones, it’s clear that having a particular mobile app on their phone will subconsciously reinforce your brand message. Every time they browse through their apps, they will see your logo, which will increase brand recognition.
  • Creating a direct marketing channel. A mobile app can provide your customers with all the relevant information they require, including a description of your products or services, prices, promotions, FAQ, and even connect them with customer service agents. All this will be at their fingertips via a dedicated mobile app, something which can accelerate their purchasing decisions.
  • Providing value to your customers. We live in a digital age, so instead of a point-collection card, automate the process and have your customers qualify for discounts by collecting points on their mobile app. Needless to say, this will generate more app downloads and a higher ROI.
  • Increasing customer engagement. A dedicated mobile app is an excellent way of opening new lines of communication with your customers to allow them to reach you instantly. With this process being so simple, they are likely to use this means to get in touch when they need to solve any potential issues that they have with your products or services. This is essential for customer retention.

Back in 2016, the global app market was worth a mouthwatering $45 billion. This doubled in size to more than $100 billion in 2020.

It is safe to say that we need top app developers and mobile app development services more than ever.

Though globalization has given us access to large pools of overseas developers, who are often willing to work for less money, none of this matters if these people are not the best app developers with both the motivation and expertise to get the job done right.

Fundamental to getting the best usable product is creating an effective mobile app development process and finding the right software development individuals or development team to make it happen.

How a Good Interview Can Help You Find Top App Developers?

While hiring a remote app developer or dev team is not quite the same as taking on a new member of staff, there are many similar processes and techniques that can be used to recruit and test out suitable candidates. This goes for both Android and iOS developers alike.

Any interviewer can successfully root out the right candidate when they have the right tools and methods.

When it comes to interviewing iOS or Android app developers, the main problem that most interviewers face is the gap in their own knowledge or experience.

Those with little to no background in coding and mobile app development usually have a hard time trying to find the best development engineers.

One of the things that companies learn very fast is that simply being able to code is not what makes a good developer.

In most cases, the developers who apply for the position that you are offering will almost certainly be reasonably good at writing code.

A top-notch developer will obviously have no problem when it comes to coding, but will also need to have all the other necessary skills too. In other words, your ideal candidate should be able to:

  • Work well with others
  • Communicate clearly and effectively
  • Own and learn from their mistakes
  • Understand what contributes to a good user experience

Most importantly, they should be passionate and reliable.

So, how can you find all this out in an interview to hire mobile app developers?

Well, the good news is that there are numerous techniques that can help you identify that perfect iOS or Android mobile app developer with an almost 100% chance of getting it right.

After years of interviewing developers from a variety of different backgrounds, we have amassed a wealth of experience and tricks to separate the best from the rest.

What follows is a step-by-step guide on how to identify the best mobile app developers based on a number of caveats that will determine their suitability for your particular project.

Don’t forget that just because one particular candidate might seem ideal at first sight, after conducting an interview based on the methodology we outline below, you may well find that they are far less suitable than you originally thought.

What Makes a Good App Developer?

“I can write good code and always get my projects completed on time.”

Sound familiar?

Anyone who has ever tried to hire an iOs or Android app developer has most certainly heard a variation of this line.

The problem is that it tells you almost nothing about the individual you are interviewing.

To understand how to find an exceptional mobile developer, you must first understand what it means to be one.

If you are new to software development then it’s easy to gaze jealousy at other companies’ apps and fall into the trap of assuming they were created without any bumps in the road, as they say.

This is nonsense. No app project in history has ever been developed without having at least a few problems.

This is why you need a great developer who is not just good at writing code but also has the following strengths:


Your new developer might be a code-writing god, but if they lack passion, your project is almost certainly going to end up being a Buick rather than a Corvette.

Passion breeds perfection, and without it, there’s little chance your project will shine.

A passionate developer is the kind of person who eats, sleeps, and dreams code.

For these people, programming is an art that allows them to build beautiful and useful things.

You’ll often find such a dedicated and passionate professional discussing the latest industry trends and helping others out by answering questions on forums etc.

If you manage to find that one-of-a-kind developer, you can count on them to stay up all night debugging code just to make sure the problem you noticed gets fixed ASAP.

For these people, the challenge is the ‘juice’, and they take pride in delivering perfection.


Your new hire should be excellent at writing code. That’s a must.

Establishing whether or not they are is relatively straightforward.

Just give them a test and see how they perform.

Another way to judge their knowledge of programming is by checking their previous experience.

Browse through their portfolio and run a background check on them with past employers to establish whether all that work is actually theirs.

Added to this, your developer should have a good all-round skillset. They should have good knowledge of all the main programming languages such as Objective-c, React Native, Kotlin, Java, and Swift for Apple systems.

Experience In iOS or Android App Development

Now comes the double-edged sword.

As a general rule, the more experience a developer has, the less likely they are going to run into unforeseen problems.

This gives project planners and managers much more flexibility, as an experienced developer will be able to quickly modify problems or build additional features etc.

Experience in cross-platform Android and iOS development is also very helpful. Even if you are only planning on building an Android web app, it is likely that when it takes off, you will want to convert it to iOS. If your application developers have experience in both platforms, they will be able to build it with a later conversion in mind.

To gain a better understanding of a developer’s general experience, you can ask to see examples of their past projects and coding (should someone on your staff be qualified enough to understand it.

Good Attitude

The right attitude is an essential quality of every great developer.

It’s not uncommon to find yourself in a situation in which you’ll be told, almost brusquely, that what you are asking for is impossible without providing more money, etc.

Likewise, your project manager might find your freelance developer missing deadlines or producing sloppier and sloppier work. Usually, this is down to them giving your job a low priority due to the hourly rate you are paying them less than other clients.

A good developer will always be professional and happy to explain a problem and its possible solutions out in full. Note that they will always be positive in their outlook, something that makes a huge difference when it comes to getting things done.

The ability to admit mistakes quickly and put things right is essential in a good developer.

Some experienced developers, in particular, can often let things go to their head and consequently, will never admit when they are wrong.

Readiness to Work Well as Part of a Team

Mobile app development is a complicated and time-consuming industry.

As a result, it requires numerous individuals to come together and work as a team. However, as any app development company will tell you, this is a little more complex than simply hiring the best iOS or Android developers.

Each of them needs to be able to convey requests and information to other members of the team in a clear and effective manner, while also working around any personality clashes.

Otherwise, a number of problems will arise which will place your entire project in jeopardy. Ultimately, effective mobile development depends on both the front-end and back-end coders as much as the managers.

That said, keep in mind that any app or web development project relies on good project management oversight as well as performance and communication tools to allow the project to progress smoothly and efficiently.

An experienced project manager armed with all the best project management tools is a must.

A Penchant for Always Meeting Deadlines

In any industry, bottlenecks and project delays are two of the most frustrating and unpleasant issues that keep managers awake at night.

The last thing your business needs is an unreliable developer who doesn’t seem able to meet deadlines.

The word deadline sounds scary for a reason – the idea is to emphasize the importance of getting things done on time.

Ability to See the Whole Picture

It has been demonstrated time and time again that app developers who cannot fully picture what the end goals of a mobile app development project are, as well as what the needs of the app users will be, often ends up taking more time to complete the project.

This is because they will write code without foreseeing the upcoming features, roadblocks, upgrades, changes, etc.

A good developer will know what end-users need from their code and will make it happen. What you will end up with is a great iOS or Android application.

What Makes a High-Performing Dev Team?

A high-performing dev team is required to have all the traits that make a good software developer, though with a number of other additional caveats.

Firstly, it’s important for a dev team to have a well-oiled internal development process and communication policy that helps the project run as smoothly as possible.

Since the project owner is entrusting the fate of their app idea to the dev team, these processes should keep them in the know regarding the real-time progress of the project.

All too often, inexperienced dev teams neglect their clients by not keeping them regularly updated with their project’s progress, also often failing to inform them of any problems or issues that could affect or delay the project later on down the line. Another area of neglect occurs when they repeatedly take a long time to respond to client queries.

Since a dev team is often a group of individuals who work together in remote locations and not just the United States, dev team managers are often unable to keep the project and its progress completely transparent, especially as many mobile app programming teams are working on several projects at once.

The fact that app programmers are often working in different time zones is why all the best dev teams have set processes, which include regular progress reports, in order to make sure everything is on course.
