App Development


Applications for smartphones have been very popular for several years. Owners of today’s devices download different applications to their devices, with the help of which they can not only communicate or diversify their free time but also work or study.

Creating applications for mobile devices – it’s quite a complex and long-term process, which requires certain skills and abilities from the developers. Therefore, only specialists who can competently analyze the market and run web projects at a professional level should be trusted with the development.

What is the development of mobile applications?

The process of mobile application development is a set of works on writing code to run programs that will work on mobile platforms. These programs can be built into the device immediately or independently installed by the owner of the gadget.

The main focus during the development of mobile applications is to create an attractive user interface, which is the key element between the software and the user. Also, creators have to take into consideration such important parameters as the size of the screens, the set of necessary functions, and reducing the number of pushes on keyboards while users are working with the application.

It is safe to say that developing a mobile app is not just about programmers writing code. It is a creative process that consists of many diverse tasks.

What does a mobile app developer need to know?

The main task of the developer is to launch convenient and feature-sophisticated software applications that will work smoothly and have the functionality available to users. To create mobile applications, a specialist needs a large number of special skills. He draws up the terms of reference, builds the architecture of the project, writes the code, discusses all the details with the customer, and works with designers and other specialists involved in the work on the order.

During the development of applications for iOS, programmers use the new languages Swift or Objective-C. It is the programmers who create projects for iOS that make the most money.

To develop applications for Android, the popular programming language Java is used. It is chosen for its high reliability. It is believed that this language is optimal for launching projects on the Android platform.

For whichever platform is being developed, the programmer will need professional technical skills such as:

  • knowledge of different programming languages;
  • knowledge of the features of popular platforms iOS and Android;
  • knowledge of the features of releases on Google Play and AppStore;
  • CSS, HTML;
  • XML, HTTP;
  • fluency in technical English.

Features of mobile app development

A key feature of custom mobile app development is the focus on the screen of each specific device. Modern gadgets can have screens of different shapes and sizes. This is why it is so important to base the project launch solely on the actual user experience.
Another peculiarity in mobile app development is the wide variety of mobile devices for which projects are launched. Programmers must take into account all the features of the devices on which the app will run.
And another peculiarity in the development of mobile applications is their performance, which is directly dependent on the availability of the Internet. Despite the fact that modern applications are superior to most older computers in terms of performance, their functionality is directly dependent on the connection to cloud services and the Internet.


As in the process of launching any modern web project, there are several necessary steps in terms of mobile app development, arranged in a certain sequence. It is worth noting that when selecting the steps for launching applications, it is necessary to focus on the needs of the user and the interface.

There are marked such stages of mobile app development as:

Planning and design

At the very beginning of the project, design layouts are created. For this purpose, the design specialist creates several program windows for the approval of the supervisor and the customer. The task of this stage of creating a mobile app is to define and approve the main design concept of the project. After all, this is the step where any changes can be promptly made. After the final approval of the concept, the designer moves on to its full implementation.


A specialist begins to develop a mobile app with an approved requirements specification and a ready design project. The programmer writes the code and adds to it everything that was approved at the initial stage of coordination with the customer. It is recommended to develop mobile applications exactly on those gadgets on which it is planned to use them in the future. This way you can test the app even at the creation stages.


During mobile app development, the testing process is a must. The main task of specialists is to ensure that the program works perfectly on release, to guarantee an inexpensive further promotion. And this can be achieved only through constant testing, for which no resources should be spared.

During testing, you can not only find and eliminate bugs in the program but also assess the convenience and ease of use of the application. These are the factors that will be key for users.

Testing applications for mobile devices on iOS is easier than on the Android platform. This is due to the peculiarities of software creation for Apple devices. The total percentage of mobile devices on Android is approximately 80%. In this case, the peculiarity of creating programs for devices on this platform will be their great variety. Devices from different manufacturers with different configurations function on Android.


After the development of a mobile app and its launch, another important stage begins support. For its high-quality implementation, it is important to build communication with users to receive feedback about the app and its functionality. It is important to promptly respond to negative feedback and take into consideration all the suggestions from users during the mobile app development process. Use their feedback and comments to improve the app’s functionality.


The specifics of creating mobile applications are that you can never know for sure how popular the program will be. It is important to keep in mind that many factors will influence the demand for the application from users. Trying to copy successful products in this case is useless. Only a competent analysis of current trends and user preferences will help achieve a good result.

Market trends

Current trends in the mobile device market suggest that most of the equipment sold is based on the Android platform. The reason for this is the availability of affordable devices, which is attractive both to development companies and customers. Nevertheless, applications for Apple cell phones are also popular and in demand from users. Although the volume of devices supplied and sold is much smaller.

Application development price

It is practically impossible to determine the final cost of creating a mobile app at once. You can only be guided by approximate data gathered from working with previous projects.

To determine the exact cost of developing a mobile application, it is necessary to first agree on all the features and functions of the future project. To reduce the cost of launching a mobile application, it is recommended to choose one main operating system, taking into account the specifics of which the work will be carried out. After comparing these data, you can choose the most suitable option.


If you want to get a high-quality program that will function efficiently and smoothly, it is best to order mobile application development from professional agencies. Web studios have whole teams of specialists who can launch a web project of any type and level of complexity in the shortest possible time.
