Explanation
A web app (web application) is software that runs entirely in the browser. Unlike a native app downloaded from an app store, a web app requires no installation: open a URL and it works. Modern web apps (PWA — Progressive Web Apps) can also work offline, send notifications, and be installed on the home screen, blurring the line with native apps.
Real-world example
A sales rep opens a URL on their tablet and accesses the company's product catalog — interactive, up to date, and working offline thanks to the PWA cache.
Practical applications
- Business dashboards and SaaS management tools accessible from any browser
- Interactive product catalogs with offline mode for field sales teams
- Internal training platforms accessible without app store deployment
- Event apps shared via QR code: schedule, map, notifications
Web app vs native app
Web App (browser)
- No installation — accessible via URL
- Single codebase for all platforms (desktop, mobile, tablet)
- Instant updates without user action
- Limited access to some device sensors
Example: easystory360 is a web app: creation and publishing of 360° experiences directly in the browser
Native App (installed)
- Downloaded from App Store or Google Play
- Full access to device hardware (camera, sensors, GPS)
- Better performance for graphics-intensive tasks
- Separate development for iOS and Android
Example: easyplayer360: native mobile reader for offline VR playback on headsets and smartphones
Why it matters in professional VR
- Web apps eliminate the installation barrier — critical for broad distribution
- PWA technologies bring native-like capabilities to the browser
- The web app model enables instant deployment and seamless updates
- Ideal for B2B tools, catalogs, and any scenario where users cannot or will not install an app
