When browsing the web on your mobile, have you ever noticed a bar appear at the bottom of your screen with the words “Add to Home Screen?” If you’re prompted to do this, there’s a good chance that you’re dealing with a Progressive Web Application (PWA).
Progressive Web Apps are not new ‘per se’ and were identified by Gartner as far back as 2017 as a key component of any company’s overall mobile development strategy. Interest, though, has intensified with the latest browser developments (notably the use of Trusted Web Activities or TWAs in Chrome 72) and retail commentators, such as Jason “RetailGeek” Goldberg, who leads the Commerce and Content practice at Sapient Razorfish, recently identified Progressive Web Apps as a trend that would come to prominence in 2019 in a podcast for the National Retailer Federation (NRF). There, the feeling was expressed that Progressive Web Apps can serve as the bridge between desktop experiences and native mobile app experiences and can help reduce the disparity between conversion rates for desktop and mobile.
AT ITMAGINATION, we believe that Progressive Web Applications can be a cost-effective way to implement the first steps of a mobile strategy by avoiding the often-heavy investment sometimes required to develop native apps. Alternatively, they can complement and extend an existing mobile strategy and make services more easily available to users on lower-end devices, suffer from weaker connectivity or who – for whatever reason – are simply more cautious about downloading apps or signing up to services.
When discussing mobile app strategy with ITMAGINATION clients, we’re observing three key reasons for companies to strongly consider Progressive Web Apps. They are:
PWAs have the potential to increase user engagement with your brand. Thanks to the ability for the web app to be added to a user’s home screen, a user can access the web app in much the same way that they would access a native mobile app, and in a way that is much quicker than opening your favored web browser and then typing in a specified URL or selecting from a list of bookmarked sites. Also, once within the web app, tell-tale signs that you’re on the ‘normal’ web – such as the address bar – disappear, leaving you with the look, feel and experience of a native mobile app. Furthermore, within the web app, you might be invited to accept notifications from the app’s publishers, meaning that a brand can ‘push’ notifications in much the same way as it would with a native mobile app.
At ITMAGINATION, we and our clients recognize that users are becoming increasingly demanding and the apps we build must be convenient to use, and sufficiently flexible to meet the on- and off-line (e.g. travel) lifestyles and needs of these users. A failure to recognize and accommodate user’s needs can be the difference between taking your user to a whole new level of engagement or losing them to a brand that can offer them exactly what they expect from their mobile experience – regardless of whether they’re online or offline.
While the price of data transfer has come down dramatically and speed has increased in recent years, this has happened in line with an overall decrease in user patience and heightening of expectations. Users expect their experiences to load and requests to be fulfilled almost immediately. At ITMAGINATION, we recognize that the time taken to load the experience is as important – if not more important –than the experience itself. We can’t simply assume that users will wait several seconds or more for an app to load if there’s a rival app out there that responds more quickly. If you’re stuck in the cold and wet and you need to hail a ride home, you’ll reach for the app that will get the job done fastest. The same is probably true if you’re looking to order takeaway, check when the next bus leaves, get directions while you’re out and about. Don’t be fooled into thinking you can build experiences so satisfying that they’re worth waiting longer for.
PWAs offer a whole host of benefits and are particularly worthy of consideration if your business depends on a high number of visitors and high level of engagement (i.e. longer sessions) with your online experience. In such instances, the ability to deliver the experience faster, and with less drain on data and battery can be a compelling reason to increase focus on Progressive Web Apps as an app-delivery method. Let’s consider Tinder as an example. When comparing the native version of the app on Android with the Progressive Web App version, it was observed that the PWA version loaded in less than half the speed of the native version. Furthermore, with the ‘distribution’ package, the native version weighed in at a hefty 30mb, while the PWA version was just 2.8mb – less than 10% of the native version.
The improvements in loading times can lead to dramatic business benefits. Pinterest’s browser-based experience was struggling to deliver any form of user satisfaction and was failing to encourage users to sign up, sign in or download the native mobile app. By rebuilding the existing mobile web experience using React, Redux and webpack, Pinterest was able to reduce the Time to Interactive (i.e. the time it takes for a page to become interactive and for a meaningful interaction to take place) from 23 seconds to just 5.6 seconds. Furthermore, the size of the data package needed to deliver the core home feed experience was dramatically smaller for the Progressive Web App version of Pinterest than for the iOS and Android versions – the former was able to deliver the core home feed experience in just 150k, compared to 9.6mb for Android and 56mb for iOS. These weren’t just achievements for the technical team to be proud of – the new Progressive Web App experience delivered significant business benefits over the ‘old’ mobile web experience, including:
The Pinterest example shows us that a well-constructed Progressive Web App can be effective in e-commerce and other websites where visit duration is important in contributing to some form of ‘conversion’ (e.g. buy or sign up), reduced incidence of abandoned transactions, higher basket value, etc. Similarly, media sites (such as news portals, online newspapers or magazines and blog platforms) that rely on being able to deploy ads in front of users, and so require for experiences to load quickly and for users to be on the site for as long as possible (every second counts) can also reap dramatic benefits in session time and user engagement. At the same time, companies that provide ticketing, reservation or travel services can provide compelling user experiences to users thanks to their ability to work well with limited connectivity. This opens a world of opportunities for those brands seeking to grow in geographies were high-quality connectivity cannot be taken for granted. Uber, available at m.uber, is a great example of this – it claims to be able to deliver the core ride request instance of the app in just 50kb, which means it will load super-fast even on 2G networks, which enables the brand and service to reach markets that might otherwise be out of reach.
The good news is that if you built your website or web service in the last two years, and if you did it according to modern industry standards, then there’s a good chance that you have a solid base on which to build a Progressive Web App. For a good start in building a PWA, check if your website:
It’s becoming easier and easier for Progressive Web Apps to make it onto your (and your customers’) smartphone home screen. With Google Chrome on Android and Safari for iOS (i.e. the default browsers for Android and Apple devices, respectively), adding a Progressive Web App to your home screen is a case of just one or two taps, and is often quicker than finding and downloading an app from the app store. Furthermore, with the launch of Chrome 72 and the addition of Trusted Web Activity (TWA), it’s now possible for Progressive Web Apps to be listed in the Google Play store. Microsoft – perhaps in part to boost the number of apps on its store – had already begun the process of scouring the internet, identifying services built to PWA standards, and listing them in the store without any need for action by the developer. Apple’s App Store still requires the most work (it requires a form of ‘packaging’ in the distribution pack), however, it’s still possible to build the appropriate packaging around your Progressive Web App and get it into the app store.
If you’re currently considering how to take your mobile strategy to the next level, Progressive Web Apps could be a cost-effective way to get your apps onto your users’ home screens, to get them to interact with your brand for longer and in a more meaningful way, and to realize your business objectives for mobile.
