Are PWA’s Replacing Native Mobile Apps?

A Progressive Web App is a set of best practices that together create a seamless user experience between a web application and a native mobile app. A user can download and install a PWA through their browser and enjoy the application’s functionality and features offline, from any of their devices.web application, Progressive Web Applications were created to help users cope with problems such as slow Internet speed, website load times, high friction among users, and low user engagement. Progressive Web Apps have several features that help alleviate these problems:Progressive Web Apps are fast: The data stored in the app is cached, so there is no need to rely on a network when starting up or engaging with the app. 53% of users abandon a site if it takes longer than three seconds to load, so ensuring efficient load times is crucial to a positive user experience.Progressive Web Apps are integrated: PWAs live on a user’s home screen, send push notifications, and integrate with a device’s other native apps. For example, Twitter Lite was developed as a PWA and experienced a 75 % increase in tweets sent.Progressive Web Apps are reliable: Service workers use PWA’s to effectively troubleshoot any problems, regardless of the network connection. This enables them to work more efficiently and confidently.Progressive Web Apps are engaging: Through push notifications, companies can keep users engaged on and offline by sending information, calling-to-action a specific ask, or updating the user on new features.Because of the advantageous attributes listed above, the entire user experience is immersive and fluid.Why Build a Progressive Web App?Beyond the features listed above, developing a Progressive Web App is an important consideration for any business to grow and engage with their customers in the future. It used to be that developing a native app and/or a responsive website was enough to get by. In 2019, PWA’s are a hybrid of both, and offer plenty of benefits to the organization and to the end user. Below are three of the benefits of developing and integrating a PWA:Progressive Web Apps are easily discoverable: Because search engines index PWAs as a website, a variety of layers within the PWA are indexed and discoverable as their own component parts. This greatly increases SEO readability and the chances of your PWA being searched and found online.Progressive Web Apps don’t require tedious manual updates: Because PWAs don’t live on an app store or require installation, updates to the information and functionality of them are simply published and the user has immediate access to the new information. This functionality also tremendously helps out businesses and their user acquisition strategies, as there are less barriers between their users and the offering.Progressive Web Apps save on data usage with offline functionality: In markets with expensive and/or slow internet access, offline functionality can be extremely important to an end user. Inefficient apps can also be detrimental to your battery life and overall functionality of your experience. Therefore, the ability to get value out of a PWA without having to use data or rely on a network connection is one reason why they are the future of businesses everywhere.These three advantages are only a few on a long list of ways that PWA’s are changing organizations and their strategies for engaging and interacting with their users.Why Will Progressive Web Apps Replace Native Apps?Although native apps still dominate the online landscape, PWAs may soon replace native apps as the top priority in connecting with users. Because mobile-first development is the way of the future, having a PWA to ensure the speed, reliability and functionality of an experience will be important in staying relevant and top-of-mind in the mobile app world.There isn’t much information out there that contradicts the ideas in this article that prove Progressive Web Apps are the future of business. Their lean and efficient abilities are most appealing when compared to traditional native apps or websites. It will likely be years before PWAs completely replace native apps, but the smart investment is to start thinking about how you use them to better engage with your audience and introduce yourself to new ones.At Sun Dew Solutions, developing progressive web apps are a strength of ours in which we take great pride.
