design or functionality for mobile application
Nowadays application developers have to struggle with new competitors every day. For several years, we have seen the same leading brands competing at the top, but today’s customers choose who to give their preference to every day. When it comes to applications, the market is endless, and users are much less tolerant, especially when you can install for free and then easily delete.

To develop an application successfully and not to waste precious resources, you need to define priorities. So, the question is, what is more important: product functionality vs product design?


The app functionality should not be underestimated.

Mobile apps are convenient for a modern user because any application can be accessed anytime 24/7 anywhere in the world.

However, it is necessary to maintain a balance between the proposed app functionality of the mobile application and user requirements. The ideal application includes all the necessary options to perform its direct purpose, but at the same time, it should not be overloaded.

When a new user launches an app, they immediately make an opinion about it:

  • Is it easy to use?
  • Does it have an attractive look?
  • Does it have all the features that I need?

The main question in the development of the app functionality: how to get an effective product?

For this purpose, it is necessary:

  1. Select the primary set of functions (which options are most actively handled by users), create a convenient menu, and a logical interface.
  2. To think over the design of mobile service, taking into account aesthetic characteristics and user experience.
  3. Adapt applications to operating systems, create the possibility of updating the service.

The design of a mobile application is its face. Even a great feature is easy to miss if the application looks terrible. Convenience, comfort, friendliness, and usefulness are the kinds of associations that users should have.

Of course, the design should be in line with app design trends. Users love comfortable, fast applications that are pleasant and easy to work with. What should be considered to make the design of a mobile application as attractive as possible?

Simplify the app as much as possible on how to use an application. The less steps to the goal, the better the application.

Think about movements and animation. What will the user do to return to the previous page, for example?

Concentrate on the content: remove visual noise, unnecessary information, highlight important elements.

Create a pleasant design. Color is one of the most powerful tools: it attracts attention, sets the mood, guides the application, tells what to do.

Tips for creating mobile applications

mobile apps development and design

Find out who your target audience is and understand what they want

The first step to the success of branding will be the analysis of the target audience. It is not enough to know the geolocation. It is important to understand what they expect from the app, what set of elements to place to benefit them, and what is really needed. Literally, everything depends on understanding the target audience.

Think through the structure

The structure of the mobile application should be clear and logical. From block to block, the user should draw important and valuable information. The user should easily find the answers to the questions.

Decide on the design

Responsiveness, convenience, logicality, and aesthetics are the main design requirements. Its look and concept should be fully based on the target audience’s needs and the general concept of logic.

Choose colors, fonts, and sizes in full combination with each other. Choose modern solutions, which can be viewed at the services of popular designers. The design of your app should be memorable, attractive and understandable. Do not forget that 85% of information is perceived by a person visually.


Check how the application works on different devices. The first things you need to know are your target audience and their devices, and the screen sizes that the application should support. Checking the device on different versions of the operating system will give a clear idea of the problems in use, which may occur to users of smartphones with older versions.

Test your app on real devices. Find beta users. Despite your skills in UX/UI testing, you will need a user’s help. Test your app with real people on existing devices. This process should not be automated because no automated tool can replace the human brain’s work. It is a time-consuming process but very reliable. The more users you have, the better for the final evaluation of the app.

“You don’t have to wait for the app developer to finish the whole process. You can perform testing usability long before the end result. It is worth starting testing with one implemented function to understand how user-friendly it is,” says Oleh Sadykow, a co-founder of DeviQA – leading software testing company.

Then, as soon as a new button or feature appears, it should be sent to the target audience for software testing again. In this way, you will be able to perform the test in small steps, evenly. This allows app developers to make modifications during development rather than at the final stage of the project launch.

Product functionality VS product design

If you have a limited budget or time, your top priority during app development should be improving app functionality. Give users a reason to download and a reason to come back. But if you have enough budget and time, do not ignore the fact that usability design changes should improve the user experience.
