Mobile app vs web app: which does your business need?
Web app, mobile app or progressive web app? Compare reach, cost, offline use and device features in one table, and see which fits your business.
Choose a web app when you want to reach people on any device quickly, keep costs down and update instantly. Choose a mobile app when your users live on their phones and need offline access, deep device features or an app they open every day from the home screen. For many businesses, a progressive web app gives most of the benefits of both. The right choice depends on who your users are and what they need to do.
What is a web app?
A web app runs in the browser. People open it with a link, on a phone, tablet or computer, with nothing to download. Customer portals, booking systems, dashboards and most software sold as a subscription are web apps.
- Works on every device with a modern browser.
- No app store approval; updates go live immediately.
- One codebase for everyone.
- Discoverable through search engines and shareable with a link.
What is a mobile app?
A mobile app is installed from the App Store or Google Play and lives on the phone. Banking apps, delivery apps and fitness trackers are typical examples.
- Opens from the home screen and can work offline.
- Full access to device features such as the camera, location, biometrics and background tasks.
- Push notifications that reliably bring people back.
- Listed in the app stores, with ratings and reviews.

When to choose a web app
- You are building a portal, dashboard, booking system or internal tool.
- Your users work on computers as much as phones.
- You want to launch quickly and improve based on feedback.
- You need search engines to find the product, or you want people to sign up from a link.
- You are validating an idea before investing in a mobile app.

When to choose a mobile app
- Your users are mostly on phones and use the product every day.
- The app must work without a connection, such as for field service, delivery or travel.
- It depends on device features: the camera, precise location, health data, Bluetooth or background tasks.
- Being in the app stores matters to how customers find you.
- Home screen presence and notifications are central to bringing people back.

When a progressive web app is the answer
A progressive web app is a web app that can be added to the home screen, work offline and send notifications. It is built and updated like a website, so it keeps the speed and cost advantages of the web.
It fits businesses that want customers to come back regularly, such as for bookings, orders or account management, without the cost and delay of app store releases. It is not the right fit when the app needs deep device integration or app store visibility.
Our recommendation
For most businesses, start with a web app or progressive web app. Launch, learn what your users do, and build the mobile app when you know it is worth it. The backend, data and much of the design carry over, so the first build is not wasted.
Questions people ask
What is the difference between a mobile app and a web app?
A web app runs in a browser and is reached through a link, on any device. A mobile app is installed from the App Store or Google Play and lives on the phone, with fuller access to device features and offline use. Web apps are usually faster and cheaper to build and update; mobile apps offer a deeper on-phone experience.
Is a web app cheaper than a mobile app?
Usually. One web app serves every device and can be updated instantly, with no app store review. A mobile app needs builds for iOS and Android (or a cross-platform framework), store submissions and updates for each new operating system release.
What is a progressive web app?
A progressive web app (PWA) is a web app that can be added to the home screen, work offline and send notifications, while still being built and updated as a website. It is often the best middle ground for businesses that want app-like features without app store distribution.
Can I start with a web app and build a mobile app later?
Yes, and it is often the smartest order. A web app lets you validate the product and learn what users need. The backend and much of the design can then be reused when you build the mobile app.
