Web App vs Mobile App: Which Should Your Business Build?
How to decide based on your users, budget and how often they will use it.
Build a web app when users work at a desk, need large screens for data, or use the tool occasionally. Build a mobile app when users are on the move, use it daily, or need the camera, GPS, offline mode or push notifications. Many businesses need both, sharing one backend.
- A web app reaches every device through a browser with one codebase.
- A mobile app is worth it when daily use, notifications or device hardware matter.
- A shared backend and API let you start with one and add the other later.
When is a web app the better choice?
Web apps suit admin dashboards, back offices, customer portals and SaaS tools, anything used at a desk with a keyboard and a large screen. They need no installation, update instantly for every user and are usually cheaper to build first.
When is a mobile app the better choice?
Mobile apps suit field staff, customers who return every day, and features that rely on the phone itself: camera, location, offline access and push notifications. They also give you a presence in the App Store and Google Play.
Can you have both?
Yes. The common pattern is one backend and API with a web app for staff and a mobile app for customers or field teams. CorectaSub is a web back office; our mobile projects are Flutter apps for iOS.

Frequently asked questions
What is a progressive web app?
A web app that can be installed on the home screen and work partly offline. It is a middle ground, but with fewer device features than a native or Flutter app.
