Posted on by prompassorn

We’ve previously discussed Progressive Web Apps (PWA) briefly, but today let’s take a deeper look at the key features of PWAs and the related services to help you better understand them.

Key Features of Progressive Web App (PWA)

  1. App-like Experience

PWAs are designed to look and behave like native mobile applications:

  • Display in fullscreen mode
  • Support smooth touch and scroll interactions
  • Include app icons and splash screens like native apps
  • Users feel like they’re using a real app, not just browsing a website
  1. Accessible via the Web Without Installing from a Store

Users can access the app directly through a URL without downloading it from the App Store or Play Store:

  • Reduces access steps, improving conversion rates
  • Can be “Added to Home Screen” for future use
  • Ideal for organizations aiming to lower app distribution costs
  1. Fast Loading – Even with Poor Internet Connections

PWAs use Service Worker technology to:

  • Cache important files such as HTML, CSS, JS, and images in advance
  • Avoid reloading the same data every time
  • Enhance page loading speed even on slow networks
  1. Partial Offline Functionality

Even without internet, users can:

  • Open cached pages
  • View previously loaded data or use basic features like forms and saving data locally
  • Sync data automatically once back online
  1. Responsive and Device-Independent

PWAs are designed with a responsive, mobile-first approach:

  • Compatible with mobile phones, tablets, laptops, and desktops
  • UI adjusts automatically to fit screen sizes
  • No need to create separate versions for different devices
  1. Secure

PWAs must operate over HTTPS to:

  • Prevent man-in-the-middle attacks
  • Build trust with users
  • Enable use of Service Workers and Push Notifications
  1. Push Notifications

PWAs can send push notifications just like native apps:

  • Send real-time promotions, news, or updates
  • Re-engage users and bring them back to the app
  • Great for news websites, e-commerce platforms, or subscription services
