Progressive Web App

PWA

A Progressive Web App (PWA) is a web application that behaves like a native app: it can be installed on the home screen, works offline, and sends push notifications. PWAs combine the reach of the web with the user experience of native apps — without App Store publication and without separate codebases for iOS and Android.

Why does this matter?

PWAs eliminate the cost of separate app development: a single codebase serves website, Android, and iOS simultaneously. For mid-sized businesses, PWAs are especially attractive when customers or field staff need an app-like experience — without the effort and cost of native app development.

How IJONIS uses this

We develop PWAs based on Next.js with Service Worker caching, Web App Manifest, and offline-first strategies. For data synchronization with intermittent connectivity, we implement Background Sync with IndexedDB. The result: an app experience accessible directly through the browser — no App Store, no installation barrier.

Frequently Asked Questions

Do I still need a native app if I have a PWA?
For 80% of use cases, no. PWAs cover offline access, push notifications, and home screen installation. Native apps remain necessary only for hardware-close features (Bluetooth, NFC, ARKit), gaming, or when App Store presence is strategically important.
Do PWAs work on iPhones?
Yes, since iOS 16.4 Apple also supports push notifications for PWAs. Home screen installation and offline functionality were available before. Some advanced APIs (Background Sync) are limited on iOS, but functionality is complete for most business applications.
