A Progressive Web Apps (PWA) is an application that uses modern development or coding technologies to provide users with a very close (if not better) experience to a native application.

In comparison to regular apps, hybrid mobile apps,  The term “progressive” refers to the fact that they introduce new functionality and, from the point of view of the user experience, they are initially viewed as regular websites but are increasingly more like mobile apps, inter alia multiplatform.

The main features of PWA are:

  • Discoverable by Search EnginesProgressive web apps look like apps, but work like websites. This means they are accessible through a URL and can be found by search engines such as Google and Bing.
  • Progressive — They work for every user, regardless of the browser chosen because they are built at the base with progressive improvement principles.
  • Responsive — They adapt to the various screen sizes: desktop, mobile, tablet, or dimensions that can later become available.
  • No impact of Battery Life — PWAs Do Not Increase Battery Usage
  • Affordable — Developing a Progressive Web App is significantly cheaper than native mobile applications. Normal mobile applications are platform-specific and need to be developed separately for Apple, Android or others. This can take up to $20k – $80k for developing an app for all the platforms which all the start-ups and small businesses can’t afford.
  • App-like — They behave with the user as if they were native apps, in terms of interaction and navigation.
  • Updated — Information is always up-to-date thanks to the data update process offered by service workers.
  • Secure — Exposed over HTTPS protocol to prevent the connection from displaying information or altering the contents. This is another argument I just shake my head at, requiring a TLS certificate and serving a site using HTTPS is not a bad thing.
  • UpToDate — Progressive Web Apps Do Work on Older Hardware & Browsers
  • Searchable — They are identified as “applications” and are indexed by search engines.
  • Reactivable — Make it easy to reactivate the application thanks to capabilities such as web notifications.
  • Push Notification — Another advantage of a progressive web app is the option of push notification. This allows developers and owners to send quick messages to their users about new alerts, newsletters, content, product, update or anything else.
  • Installable — They allow the user to “save” the apps that he considers most useful with the corresponding icon on the screen of his mobile terminal (home screen) without having to face all the steps and problems related to the use of the app store.
  • Linkable — Easily shared via URL without complex installations.
  • No App Store/Zero Installation — All the app stores have certain rules and conditions which developers have to follow so that their app can be accepted by them.
  • Offline — Once more it is about putting the user before everything, avoiding the usual error message in case of weak or no connection. The PWA are based on two particularities: first of all the ‘skeleton’ of the app, which recalls the page structure, even if its contents do not respond and its elements include the header, the page layout, as well as an illustration that signals that the page is loading.
  • Easily Migrate  Functionality — Another big advantage of PWA is that you can easily migrate your current website into PWA with the help of dedicated PWA developers. All you need to hire the top PWA app development companies, request quotes and get started with your next PWA project!

Drawbacks of Progressive Web Apps

1. Limited Browser Support
Still a new technology – all browsers don’t support it fully yet. Progressive Web Apps are Android-centric and do not work on popular browsers, including IE, Edge, and Safari.

2. Fewer functionalities and therefore less UX
Unlike native apps, these web applications have fewer features. iOS does not support all functionalities of PWAs on Apple devices. As a result, the possibilities of PWAs are limited for many users

3. Need Expert Developers Assistance?
If you are looking to hire react native developers, flutter developers or developers to build your progressive web apps then we have the perfect team for you. At Samarpan Infotech we have experienced and skilled developers, designers, analysts to work on your project.

4. No chance of promotion in app stores.
Although this fact eliminates the need for excessive coordination with app stores, it also deprives companies of an efficient source of promotion.

5. Can’t access phone’ features.
They do not have access to all the features of the phone: This can be considered as an important weak point for PWAs compared to native applications.

6. Low performance for graphics- Intensive apps – for most applications

7. Native plugins – while hybrid apps can access practically all the native device features, they’re dependent on plugins.
