Progressive Web Application (PWA) design is a wonderful way to combine the best functions of native apps with the convenience and reduced cost of websites. Indeed, a progressive web app is similar to a native application and also, PWAs make the use of mobile web more effective for you and for your customers alike. Benefits include rapid loading, connectivity for various internet speeds, responsive design, offline functionality and push notifications. In addition to that, PWAs ensure consistency in user interface and user experience. This consistency means users have to be familiar with only one interface and get the same experience from it. All these considered, we develop PWAs to deliver all these benefits and give real boost to your business! 

PWA design process in Roundium

  • 01

    Product discovery

    The application development process starts with an exploratory discussion that helps us gain understanding of your needs, business goals, and audience. In return, it saves you time and ensures that the end product is cost-effective and meets end users’ needs. Our team gathers and analyzes information about the project and your business in general. This is how we identify your needs and work out the whole PWA design process that best fits those needs. Product discovery allows us to realize the scope and limitations of the project. We define the direction of the application development process and create a plan to take your product from initial ideas to launch. This phase of the app design process involves estimation of the budget, establishment of timeline and selection of fitting technologies. In order to reach these predefined goals we rely on productive communication and always make sure the project is on track. This initial stage of PWA design is critical for a successful end product.

    UI and UX design

    UI stands for User Interface. It is the system through which a user interacts with your application. With optimization, our application development team builds an attractive and responsive UI. The interface must be consistent and easy to use in order to secure smooth and lasting user engagement. Graphic elements of your PWA, such as pens, images, layouts and color schemes, are all integral parts of the UI design. UX stands for User Experience. As a special area within application design, UX focuses on users’ feelings and behavior. We learn more about your business so we understand your product vision and your audience. Knowing your customers allows us to optimize your PWA for effective and enjoyable use. We are aware of the importance of good user experience. Customers who have poor user experience are most likely to make a purchase somewhere else - and we can’t let that happen.

    At the developmental stage of application design we create the actual functional site for you. Our team brings an app to life that has the full potential to generate traffic and conversion. We utilize the information generated during the previous stages then we carry out the programming. We integrate the technical features and put all the necessary modules in place. Our PWA design team uses a range of software development technologies such as Python in order to ensure high levels of security and performance for your application.

    Test and debug

    Testing and Debugging are essential stages in the PWA design process. While we perform testing in order to find out if there are errors, debugging is for detecting and fixing these errors. During the test phase we thoroughly inspect the application to check if it meets user needs, which is vital when it comes to the success of your PWA. Debugging is the phase that follows tests. It plays a critical role in PWA design as the process during which our team fixes every possible bug in the software. This procedure involves identification, analysis and removal of errors. This allows us to make sure your application meets the criteria of functionality, security and performance. Once testing and debugging have been completed, your PWA is ready to launch.

    An attractive and optimized app is fundamental but the PWA design process doesn’t end once your app has been activated. The significance of regular maintenance should never be overlooked. In fact, lack of proper maintenance work can cause a number of issues that potentially harms your business. Therefore, well-conducted regular maintenance of your app is essential for your business in order to engage and keep customers. We can regularly check your application for issues and fix those problems so you can always be sure your application is functioning properly. Our PWA design team makes updates in order to keep your application up to date.  The benefits of our services are manifold. Regular maintenance by our team ensures a constant high level of user experience and encourages potential customers to stay and make purchases on your app. Also, by keeping security systems up to date, maintenance provides protection from cyber attacks.

Technologies We Use


React is a JavaScript library used in application development to build interactive elements in PWAs. JavaScript is a coding language our developers use to add interactive features to Progressive Web Applications. Not only is it fast, simple and scalable but also, is a high-performing yet flexible framework that is easy to maintain. To put it another way, it means considerable cost and time benefit for your business.


The first user impression is always very important in case of PWA design, therefore, when customers look at your app it is crucial that they find it visually appealing and attractive. Cascading Style Sheets (CSS) is a technology we use to achieve that. Using CSS3, the latest version of this language, we set up and organize the visual features, including fonts, colors and layout that make your website look good. CSS3 is a cost-effective, time-saving solution supported by most browsers.


HTML5 is an improved version of the original HTML standard. HTML5-based PWA design allows users to access Progressive Web Apps even without being connected to the Internet.

Also, you can easily add multimedia features to your PWA without using Adobe Flash or any other third-party plugin. Browsers such as Firefox, Chrome, Safari and Opera all support HTML5. Using HTML5 PWA design has numerous benefits for businesses that are interested in having content that is responsive to various web browsers and devices.


Push notifications are special messages and alerts which applications display for the users who use your app. What’s more, these notifications show up even if your app is currently not opened by a user. Each major mobile platform has support for push notifications — for instance iOS, Android, Windows and BlackBerry all have their own services. Push notifications are to deliver timely and informative content, such as updates, promotions and deals. Push notifications play an important role in PWA design as top drivers of mobile consumer engagement and retention. So take advantage of push notifications as a way to stimulate user engagement. Maximize your reach and increase the ROI of your app.


JavaScript is a programming language we use to create and manage dynamic content for PWAs. In other words, we add graphics and other content features that move, refresh, or otherwise change on your screen without you having to manually reload a page. In fact, this is a key factor in PWA design. Java is object-oriented. Object orientation means that it follows a programming style that relies on concepts such as class and object. Object orientation helps to keep the software system modular and flexible. Integrating such flexibility and enhanced visuals, our developers use JavaScript to create attractive and engaging progressive PWAs.


Firebase is a mobile application design toolkit and platform built on Google infrastructure. All of the data, products, and services are backed by Google components. Firebase offers some powerful features for developing, handling, and enhancing PWAs. Among others, we can optimize ads or add chat and photo sharing functions. Regardless of the size of your app, Firebase also scales automatically. Consequently, by using Firebase we can create improved mobile apps to support your business.

Advanced PWA web application design

What is PWA?

A Progressive Web App introduced by Google in 2015, also known as a PWA, is the best way to create a mobile app from web applications to load faster and higher performance. A Progressive Web App does not need to be uploaded to Google Play or Apple Store since it is an application that will be downloaded directly from your website on an Android, iOS, Windows, and Mac device. Progressive Web Apps are web pages that use current web standards to enable web-to-app conversion. It offers a user experience similar to the native application for the users.

What are the benefits of PWA?

  • Automatic PWA update in WordPress and no need to update with coding
  • PWA responsiveness means that this technology is well displayed on all devices such as mobile, ‌ site, computer, and.
  • Possibility of PWA service with the help of Service Workers in case of the weak internet
  • PWA services are always provided using HTTPS so that no unauthorized person can interfere with encryption.
  • Push Notifications feature in PWA.
  • Ability to share PWA via URL and search it in search engines
  • Compatibility with different devices and having the appearance of native applications
  • Ability to install PWA on mobile phones like other Native applications.

The difference between usual applications and PWA web applications

PWA do get more benefits that native apps have, although some of these benefits are limited, particularly on iOS. PWA web applications and Native applications have the same efficiency in terms of User Interfere.

ٌWhy you need a progressive web application?


PWA web applications should be leveraged as a part of every existing mobile strategy because they are practical, useful, and fast. With our cost-effective PWA apps, save your time and manage your business easily.

Service Workers

Service workers are a vital element of PWAs. A service worker is a script run by the browser in the background. Depending on the availability of the network, the service worker, acting as a proxy, will serve the items from its cache or retrieve them from the network on the server. Service workers make it possible to use the PWA offline.

Server-side notifications (Push Notification)

Among other tasks, service workers are also responsible for receiving push notifications on your PWA. Your PWA can receive push notifications. Most recent Web browsers assume this functionality.

Application shell architecture

The shell app is the skeleton of your PWA. It contains the UI and the essential components to build your app in the browser. The shell app saves your PWA UI locally, while the content is dynamically retrieved through an API.

Well-known services that use PWA

Many well-known services adopt PWA web applications such as Uber,‌ Lift, Pinterest, Break Lock, and Kartik. Iranian examples also include Digi Kala, Snap, Tepsi, and Irancell lenses, which have provided a good user experience for the audience by using this technology.

Browsers that support PWA

For PWA to run on smartphones, there must be two prerequisites. One is a good browser, and the other is PWA service enabled. In general, browsers that support PWA include:

  •     Fully supported desktop browsers: Chrome, Opera, Firefox, QQ Browser, and 360 Browser
  •     Less supported desktop browsers: Microsoft Edge & Travel
  •     Mobile browsers with full support: Xiaomi, Baidu, Chrome, Firefox, V chat, UC Browser, Sogou, 360 Browser, and Quark
  •     Low support mobile browsers: Samsung and QQ Browser

Will PWA replace native applications?

Progressive applications are not yet capable of replacing native applications in all aspects, which will be the case in the future. However, most applications do not require such a deep integration of hardware and software, making the PWA format perfectly suitable for most projects. Compared to native applications, PWA programming is much easier and cheaper. Progressive applications can compete with native ones in the future.
