What native app fails at?
There are 3.3 billion smartphone users in the world today. We install Android/iOS applications on our smartphones for various needs. But there are some persistent issues while installing these apps:
- We are not sure if the app we are installing is worth the download and will be used in the longer run
- Not enough disk space available most of the times
- The available internet data is insufficient
With these problems, it turns away people from installing Android/iOS apps as the experiences are not satisfactory or even worthwhile. Some even hesitate to download apps given to the recent security issues also. There are times when the apps work well only when there is an active internet connection.
The average app size available on app stores normally ranges from 30-200 MB. Also, these apps need an update in short intervals almost regularly. With the major of these apps having a fully responsive website, instead of downloading the apps, people shift to these websites which will save them ample disk space and internet data. This directly negatively affects the user engagement with the business/brand.
By 2019, 63.4 percent of all mobile phone users will access the Internet from their mobile phones. The traffic is on a perennial increment every year. Until now, mobile users have interacted with businesses online by 2 ways: mobile web and native apps. But PWA goes one step further, eliminates the drawbacks of both these ways and brings out a new perspective on the way users go about utilizing the mobile internet.
In short, PWA takes advantage of the latest the web has to offer. Progressive web apps combine great aspects of a native app with everything that is great about a mobile website.
