Web app vs native app: which should you build in 2026?

“We need an app” is one of the things we hear most often. Sometimes it is true. Other times what you need is a web app that works well on a phone, and then you have saved both money and an Apple review process. Here are the four options side by side, and the questions that decide it.

What is the difference between a web app, a PWA and a native app?

• Web app: runs in the browser on desktop, tablet and phone. No installation, no App Store. Updates go live instantly.
• PWA (progressive web app): a web app that can be added to the home screen, open without the browser bar and work partly offline.
• Cross-platform (React Native): a real app in the App Store and Google Play, built from one shared codebase for iPhone and Android.
• Native: two separate apps, one in Swift for iPhone and one in Kotlin for Android. Maximum control, double the work.

When do you need an app in the App Store?

• Users need reliable push notifications, for example about bookings, deliveries or shifts.
• The app needs the camera for scanning, such as barcodes, price labels or documents.
• It has to work without a connection, for example for staff in the field, in a warehouse or a basement.
• You need Bluetooth, NFC or background location.
• Users open it several times a week and expect to find it on the home screen.
• Being findable in the App Store matters for your brand.

If none of these apply, a web app is almost always the right first step. Customer portals, internal tools, booking pages and dashboards work very well in the browser. It is also the fastest way to test an idea before you spend money on two app stores.

Why React Native instead of native?

We build mobile apps in React Native and web apps in Next.js, both in TypeScript. That means an app and an admin panel can share logic, and the same team can look after both. At Kirppu the booking system, the renter panel and a mobile label app work together in exactly that way. Read more about React Native app development or see our mobile apps.

Common mistakes when choosing a platform

• Building an app because a competitor has one, even though users only log in once a month.
• Forgetting the admin side. Almost every app needs a web panel behind it where you manage content, users and data.
• Assuming a PWA can do everything an app can on iPhone. Push and offline are more limited.
• Building two native apps for a business app where one shared codebase would have been enough.
• Ignoring running costs. New versions of iOS and Android require updates every year, even when the app gets no new features.

What does a web app cost compared with an app?

Typical market ranges in Denmark for a simple app are DKK 50,000–150,000, a medium app DKK 150,000–500,000 and a complex one from DKK 500,000 to over 1 million. Budget 15–20% of the build cost per year for maintenance, and remember Apple’s developer account at USD 99 a year and Google’s one-off USD 25 fee. With us a web app starts at DKK 18,000 plus DKK 600 a month, and a mobile app at DKK 28,000 plus DKK 1,200 a month, both with 12 features and one integration.
