PWA vs. Native App: a Side-by-Side Comparison

PWA vs. Native App: a Side-by-Side Comparison

Have you noticed an “Add To Home Screen” notification while you were browsing websites on your smartphone?

If you clicked on it, you would see a shortcut on your device’s home screen just like a native app does. Yet the site sits bookmarked alongside all other apps. The only oddity is that you haven’t downloaded anything from app stores. This is how PWAs work.

In this article, we will dig into application development software Progressive Web Apps and native apps, bump their heads together, and draw comparisons to determine which technology is the winner of the contest: tried-and-true native applications or brand new progressive ones.

Without further ado, let’s dive right in.

Native Apps: A Quick Overview

A native app is a software program coded in a particular programming language that is created for use on a specific device or platform (Android, Windows, or iOS).

On the tech side, in order to build a native app, developers make use of dedicated frameworks and programming languages. For instance, they employ the combination of Kotlin and Java for creating Android apps, while React native and Swift are commonly used for iOS development. Thus, a native app is developed at least twice: once for iOS and the other time for Android so that a user has access to the app regardless of what their mobile OS is.

Once built, the app should be submitted to Google Play or/and AppStore to ensure that it is set up to each store’s standards. This process can take several months.

Progressive Web Apps: A Quick Overview

Progressive Apps that are built with modern frameworks such as React.js or Angular, give websites the look and feel of regular smartphone apps when accessing them on a mobile web browser with no need to be downloaded from stores.

This makes Progressive Apps:

● fast
● reliable
● responsive
● secure
● easy to install
● discoverable for search engines
● accessible without the Internet
● able to send push notifications
● able to provide access to hardware and software within a user’s device such as a camera, mic, or GPS.

Kindly note that a PWA has a single database for all platforms. The app basically works as a responsive site on desktops or as a native app on mobile devices. Because it doesn’t require a download, users may have no idea that they are using a progressive app.

The solution was introduced by Google in 2015. Right off the bat, the biggest brands such as Lancome, Adidas, END Clothing, Flipkart jumped on the bandwagon and now this relatively new tech is becoming incredibly popular.

But do progressive web apps compare to native ones?

What is the Difference?

In order to choose between a progressive and native app for your company’s mobile presence, it is essential to know the difference between them as far as each development methodology has both its pros and cons. We are going to break out the core differentiators:

● Installation
● Offline Usage
● Push Notification
● Device features
● Updates
● UX/UI
● Cost

1. Installation process

Native apps can be found and installed through either Google Play or App Store. End users can find them by typing popular keywords or a brand name in a store’s search bar. It should be mentioned that native apps are massive. For example, the average Android app file size is 11 MB, while the weight of the average iOS app is 34 MB. Needless to say that in this scenario the installation process can take a lot of time. Besides, most mobile users open the native app once or twice a month. At other times, it remains unused “collecting dust” and taking effective disk space.

A PWA is a different story. Since they are downloaded and run on a mobile browser, they take a little space. Thus, the average PWA file size is just 350 KB so the installation process takes a few seconds and can be done in a click without visiting an app store (as you can see at the screenshot). So, progressive applications are the clear winners in this category.

2. Offline Usage

Some time ago, the ability to access the content users want without an Internet connection remained the prerogative of native apps. But things have changed. The uprise of PWAs can boast the same capabilities. They utilize cached data to provide offline use.

But here is the thing. A progressive app can serve only certain parts of the content to users when their device is disconnected. As such, anything that is not part of the page’s caching system will be unavailable until connectivity is restored. For example, if a user wants to submit a request through the contact form or make a reservation, they will be unable to do so.

In this scenario, native apps win when it comes to offline usage. Even though the PWA technology is caching up some content and allowing users to access it, it is still kiss up to native apps in providing offline functionality.

3. Push Notifications

Push notifications are robust re-engagement tools and the key reasons why many e-commerce website owners are building an app. A successful push notification strategy will result in better engagement with your content.

With native apps, you can build the required functionality from the ground up or integrate it into an app with the help of third-party services such as PushBots or OneSignal.

With PWAs, the push notification functionality can be implemented thanks to service workers. However, the truth is that at this point, this functionality is still limited to Chrome, Opera, Safari, and Mozilla browsers and practically is not available on iOS devices. Of course, you can use push-notification with a PWA to re-engage your Android customers, but you can’t do the same for your iOS users for a while.
Native apps are the clear winners in this category as far as they support push-notifications on both Android and iOS devices.

4. Device features

When we say that an app is “native”, that means it is developed to run in a specific software environment. As such, a native iOS app is tailored to Apple’s hardware, as well as incorporates Apple-specific features, say, its Face ID. The same goes for Android and Windows apps.

Thus, native apps can use the:

● GPS
● camera
● fingerprint scanner
● accelerometer
● compass
● contact list
● alarm
● calendar
● mobile payments, and so on.

Progressive apps use HTML, JS, and CSS to build out many of the same features contained in a native app. However, PWAs can’t take advantage of these features to its full extent. Of course, you can make some connections through APIs to improve the UX, but still limitations exist. As such, progressive apps can use the device’s hardware, say, mic or camera, but they can’t take advantage of low-level hardware features like a fingerprint scanner, GPS, or 3D graphics rendering.

5. Updates

The updating process is automated for both native and progressive apps and users can hardly detect that an update occurs. So it is nothing to do for users when it comes to updating web and progressive apps as for the most part, this process will go unnoticed. As such, there are no winners in this category.

6. UX/UI

Native apps are designed taking into account hardware’s specific capacities so that they can make use of a device to its full extent. Thanks to the fact that the interface is smoothly combined with a smartphone, this creates a perfect UX. However, in order to develop an interface for at least two platforms from the ground up, solid knowledge of native mobile languages, for example, Swift or React Native is required.

As far as PWAs are concerned, their code can be reused for different platforms. You are free to use the same functionality and UI template for Android, iOS, desktops. All in all, progressive web apps provide an app-like experience to their users: they look and feel exactly like native apps but the development cost is less.
