How to Hire Freelance Mobile App Developer?

It would seem that until quite recently, we all used only desktop programs. When did the time for mobile applications come?

In 2008, Apple Inc. launched the App Store, which contained about 500 applications. Since then, the demand for mobile applications has begun to exceed the demand for desktop applications. This applies not only to the US market but also to the global market, particularly China, which produces homegrown applications such as WeChat Pay, Alipay, Taobao, etc. China dominates not only locally but also receives almost half of the revenues of the world market from the existence of applications. 

Among the various types of applications, such as Finance, Entertainment, Health & Fitness, News & Magazines, etc., mobile games are in the greatest demand. The revenue for that type of app grew from 115.9 bln $ in 2017 to 267 bln $. Social networks occupy the second place. 

According to Adjust, for marketers, mobile games account for 50% of all user acquisition ad spend across all verticals. Most of all are spent on the Asia-Pacific region, which accounts for 64% of spending. To put everything in perspective, e-commerce makes up just 16%. Mobile games monetize incredibly well, evolving and innovating with the times, which means they can fund their user acquisition activities.  

Mobile App development is a complex process. That is why if you want to hire mobile app developers, you should spend lots of energy and resources. However, companies like Mobilunity have a great network of certified and qualified developers that are ready to help anytime. They will help you to save money and precious time.

The Reasons to Hire an App Developer 

Being a business owner does not mean that you know all the latest news in the IT industry or know how to write code in Python. This is the case when companies with experience assist in outsourcing mobile development services. They know exactly how many people are needed in the team and why they should hire a web app developer. In the process of hiring a freelance mobile app developer, if your project involves a WordPress-based app, you may also need a developer to create or customize plugins tailored to your app’s specific requirements.

If you want to hire a freelance app developer, you have three options:


Hiring an in-house employee is a common practice for most companies because, in that case, you can be sure that your worker is fully committed to your company. That includes being a part of the team, engaged in the culture of the company, and being committed to the things company is working on.  

However, you should consider the cost and effort that will be spent on virtual recruiting and hiring process. Do you have the resources to conduct a proper onboarding process for your employee? And are you sure that you need a full-time employee for the long term? If the answer is “no,” try thinking about other options.  


In the post-Covid times, freelance work has become more and more popular among both employers and employees. Firms choose to hire freelance app developers because the hourly rate of mobile app developer will be much lower. 

This option has its pitfalls, such as the quality of work, onboarding process, and engagement in a team. Should this specialist be engaged in a team eventually? 


When outsourcing, communication between the customer and the executor takes place according to the model of the “client — the project manager — a team of specialists.” In such a model, the client company discusses all issues with the manager of the contractor company, and the project manager distributes tasks to his team of specialists and monitors the performance of the work. 

The main plus to onshore android app development company is reduced costs. Paying for services to an outsourcing company is much cheaper than hiring IT specialists. In addition, the provider’s team works on its territory, and therefore, there is a saving in office space. 

Android vs iOS 

Getting started on an app is about developing an idea. The next stage, which we want to tell you about, is the choice of the operating system for the program. The two main options are IOS and Android. When hiring a freelance mobile app developer, it’s essential to consider whether your project requires the expertise of a developer to create or modify plugins for seamless integration with your WordPress-based app.

There are many technical differences between the two operating rooms. However, it is necessary, first of all, for the programmers themselves to know about the intricacies of the operating system. It is important for a businessman to understand what to choose — IOS or Android.  

If you want to save money, it is better to start with the development of applications on Android and hire Android developers. Since the release of the IOS application is complicated by the App Store policy, you will have to pay for the work of programmers for a long time so that they improve the application to the maximum. Launching on Android is simpler and therefore requires smaller investments. 

The only case when it is profitable to start immediately with IOS is applications for the most well-off stratum of the population. For example, if you decide to launch applications for running a business, feel free to start with it and hire iOS developer.  

After choosing the platform and application type, you should find a freelance app developer. We decided to help a little bit with that. 

Native app  

For an ordinary user, there is practically no difference – a native or cross-platform application will be installed on his device. But going deeper into the operation of various applications, you can see that native solutions written for a specific operating system will be more convenient, have an intuitive interface, and will work faster.

FrameworksCore Data, Core Animation  FrameworkJetpack Compose, Android UI
APIs Cocoa Touch, RESTful, MetalRetrofit, GSON, EventBus

Cross-platform app

Developing applications for Android and iOS, if you create a separate solution for each operating system, increases the time and cost of the project. Given the large number of versions and varieties of operating systems, it is difficult to write separate code for each platform. This became the reason for the appearance of cross-platform applications for mobile devices and the hiring of cross platform mobile apps developers. If native applications are created for a specific operating system, then when writing the code for a cross-platform solution, it is possible to adapt the software to any OS.
