The difference in one paragraph
- Website — informational pages people read (your brochure, blog, contact). Found via Google, no install.
- Web app — software that runs in the browser and does things (dashboards, bookings, SaaS). No install, updates instantly for everyone.
- Mobile app — installed from the App Store / Play Store. Best for on-the-go use, offline access, push notifications, camera and GPS.
When each one wins
- Choose a website if you mainly need to be found and trusted, and to capture enquiries.
- Choose a web app if users work at a desk, you want instant updates, and discoverability via search matters.
- Choose a mobile app if you need push notifications, offline use, location, or an app-store presence your users expect.
The pragmatic answer: often both, on one backend
You rarely have to choose forever. Modern cross-platform tooling lets one team build a responsive web app and Android + iOS apps that share a single backend — so you reach every user without paying to build the same logic twice. This is usually the best value: start where your users are, and expand without a rebuild.
