Website, web app or mobile app: which does your idea actually need?
They sound similar but cost and behave very differently. A plain-language guide to choosing the right thing to build first.
"I need an app" is one of the most common things founders say. Sometimes it's true. Often, what they really need first is a website or a web app — which can be faster and cheaper to launch, and easier to change while you're still learning what customers want.
A website: to inform and convert
A website's job is to explain who you are, build trust and get visitors to take an action — call, book, buy or enquire. Think of a clinic, a contractor, a restaurant or an agency. The content is mostly the same for everyone who visits.
Choose a website if your goal is to be found on Google, look credible and generate leads or sales.
A web app: to let people do things
A web app runs in the browser but behaves like software. Users sign in, save information, search data, message each other or pay. Online booking platforms, marketplaces, dashboards and real estate search tools are all web apps.
Choose a web app if users need accounts, personalised data or tools — and you want it to work on any device without an app store.
A mobile app: for daily, on-the-go use
Native apps live on the phone's home screen and can use the camera, GPS, notifications and offline storage more deeply. They're great for things people use every day — fitness tracking, messaging, delivery.
But they come with extra work: two platforms (iOS and Android), app store reviews, update cycles, and the challenge of convincing people to download yet another app.
A quick way to decide
- Will people use it several times a week, on the go? A mobile app may be worth it — later.
- Do users need to log in and do something? Start with a web app.
- Do you mainly need to be found and trusted? A website is enough.
The middle ground: progressive web apps
A progressive web app (PWA) is a web app that can be added to a phone's home screen and can work more like a native app. For many early-stage products, a well-built responsive web app or PWA gets you most of the benefit of a mobile app with one codebase and no app-store approval.
