Native app, cross-platform or web app? A decision guide
Swift and Kotlin, React Native and Flutter, or a PWA. Which technology fits which project, and which questions to answer first.
Anyone planning an app faces a fundamental decision early on: build separately for iOS and Android, use one shared codebase for both platforms, or skip the app store entirely and build a web app. Each option has its place. The right one depends less on technology than on your project.
The three routes at a glance
Native development means one app in Swift for iOS and one in Kotlin for Android. You get the best integration with each operating system, full access to every feature and the typical feel of each platform. In return you maintain two codebases.
Cross-platform frameworks such as React Native or Flutter produce apps for both systems from one codebase. For most business applications this is a very good choice today: significantly less effort, and the result feels native enough.
Web apps and PWAs run in the browser and can be installed on the home screen. No app store review, instant updates, one codebase for every device. The limits are deep device features and visibility in the stores.
Five questions that make the decision easier
- Does the app need to be found in the app store? Often yes for consumers, usually not for internal tools.
- Which device features do you need? Camera and location work everywhere. Bluetooth devices, background tasks or widgets point towards native or cross-platform apps.
- How important is offline support? All three routes can work offline, with different effort.
- How often will the app change? Frequent changes benefit from web apps or a shared codebase.
- Who maintains the app later? A team with web experience gets up to speed faster with React Native or a PWA than with two native codebases.
Our rule of thumb
- Internal tools and quick market tests: web app or PWA.
- Customer apps with accounts, bookings and notifications: cross-platform.
- Apps whose core is a device feature (hardware integration, camera processing, demanding animation): native.
Importantly, the decision is rarely final. Many successful products start as a web app, learn from real users and later move to a native build where it matters.
Conclusion
There is no route that is always right. There is only one that fits your project, your budget and your team. If you are unsure, we start with a short call and a clickable prototype. After that, the choice is usually obvious.
