The difference in one paragraph
A website tells people about you and gets them to enquire or buy. A web app is software people log in to and do things with, in a browser. A mobile app is software installed on a phone, with access to notifications, the camera, biometrics and offline use.
Choose a website when
- Your goal is to be found, explain what you do and collect enquiries or sales.
- Content changes more often than functionality.
- Search engines and AI assistants are an important source of customers.
Choose a web app when
- Customers or staff need to log in: portals, dashboards, bookings, orders.
- People will mostly use it at a desk, or occasionally on a phone.
- You want one version that works everywhere, with no app store involved.
Choose a mobile app when
- People will use it several times a week, on the move.
- You need push notifications, the camera, biometrics, location or offline use.
- Being on someone's home screen is part of the strategy, as with loyalty or payments.
A sensible order
Most businesses should start with a website, add a web app when customers need to log in, and build a mobile app once there is proven repeat use. A web app built well can share its back end with a later mobile app, so the first investment is not wasted.
What drives the cost
- The number of distinct screens and user roles
- Integrations with payments, CRMs and other systems
- Whether data needs to work offline or sync in real time
- Ongoing hosting, updates and support after launch
