Important Benefits of Progressive Web Apps

Here are some of the most important benefits provided by PWAs:

benefits of pwas

1. Reduced Maintenance

When you are designing any kind of app or website then the consideration of maintenance elements is so much essential. According to the survey, the maintenance expense of native mobile apps is around 20 percent greater than its estimate development cost. Its maintenance budget completely depends on the size & scale of your app.

On the other side, progressive web applications are more cost-effective in the case of development as well as maintenance front. The overall budget incurred is considerably fewer than the native applications.

2. Offline Support

The internet is necessary for lots of native apps and the user should be continuously connected with it. However, some of the elements would be cached but still connectivity will be needed.

On the different side, PWAs leverage an aspect which is also known as Smart Caching that securely caches main information on the website (or application) so that the PWA can be easily accessed even when the internet is not available.

3. Small Size Memory Footprint

Progressive Web apps are so much tiny in size than native apps. For instance, the size of PWAs such as Facebook, Twitter, Flipkart, etc. is in only some KBs and the size of the native app is in MBs.

Therefore, PWAs may be fruitful for the business if the target audience is utilizing mid-range Smartphone that has lower RAM/ROM configurations.

4. Reduced Bounce Rate

It is too much essential to offer the best user experience to the customer otherwise they will not visit again to your app or website.

According to the survey, users generally do not like to return to the website if it takes a loading time of more than 3 seconds. However, page loading speeds on PWAs are much fewer or lower than the normal apps and websites, so consumers are more possible to like the PWA experience. A reduced bounce rate simply means that users will spend higher time on your website and this thing can boost your business.

Numerous developers think that progressive web applications are quite similar to responsive web applications. Although, there is a huge variation between both of them. The responsive web applications, as well as PWA both, focus on awareness, usability, and on functionalities, etc. but PWAs give some special kind of features that are not available with responsive web applications just like offline service as well as push notifications which are generally not available in normal responsive web apps. Also, PWAs can drive the best conversion and boost the engagement of users compared to responsive web apps.

Final Words

Simple internet accessibility as well as an improvement in the number of digital services is some major reasons behind the faster growth in Smartphone serviceability. The development of customer experience becomes more important with the exponential growth of the usage of mobile phones.
