If you're planning an app, someone will ask you early on whether you want it native or cross-platform. It sounds technical, but it's really a business decision about money, time and what your app needs to do.
The two approaches in plain English
Native means building two separate apps: one for iPhone (usually in Swift) and one for Android (usually in Kotlin). Each is written specifically for its platform.
Cross-platform means writing one app that runs on both. The two most popular frameworks are Flutter, made by Google, and React Native, made by Meta. Most of the code is shared, with small platform-specific tweaks where needed.
How they compare
| Factor | Native | Cross-platform |
|---|---|---|
| Cost and build time | Higher. You're effectively building and testing two apps | Lower. One codebase covers both platforms |
| Performance | The best possible, especially for heavy graphics | More than good enough for most business apps |
| Look and feel | Matches each platform perfectly | Can match closely, or use one consistent design on both |
| Device features | Full, immediate access to everything | Most features covered; some need extra native code |
| Maintenance | Two codebases to update and keep in sync | One codebase, so fixes and features ship to both at once |
When cross-platform is the right call
- You need both Android and iOS but have one budget.
- You're building a first version and want to launch, learn and improve quickly.
- Your app is mostly screens, forms, lists, payments and notifications. Think booking, e-commerce, delivery, education, fitness or internal business tools.
- You want new features to reach all your users at the same time.
When native is worth the extra cost
- Your app is graphics-heavy, like a game or a complex video or photo editor.
- You depend on advanced device features, such as augmented reality, specialised camera processing or long-running background tasks.
- You only need one platform anyway. If your customers are all on Android, a native Android app makes sense.
- You're at a scale where separate, dedicated iOS and Android teams are realistic.
About the myth that cross-platform apps are slow: that was a fair complaint years ago. Modern frameworks have closed most of the gap, and Flutter compiles to native machine code. For a typical business app, your users won't notice a difference.
There's also a middle path
Cross-platform apps can include small pieces of native code where a specific feature needs it. So you get the savings of one codebase for 90% of the app, and native power for the bits that need it. It's a common and sensible setup.
A simple way to decide
Ask yourself one question: does my app need something the phone does that most apps don't? If the answer is no, go cross-platform and put the money you save into design and marketing. If the answer is yes, talk it through with a developer before you commit.
