Native or cross-platform — how to choose for a business app
Choose a shared codebase when Android and iOS share the product. Choose native when platform behavior is the product.
The useful question is not which framework is popular. It is whether Android and iOS are the same product, and how much of that product depends on the platform itself.
What native means here
A native Android app is written for Android, commonly in Kotlin. A native iOS app is written for iOS, commonly in Swift. Each one can follow the platform's interface, notifications, and system behavior without a layer in between.
Two native apps mean two implementations of the same flows. That costs more when the screens are duplicated, and it costs less confusion when the platforms need to behave differently.
What a shared codebase changes
Flutter or React Native lets most of the interface live in one project and still ship to both stores. That is a good fit for catalogs, booking tools, and internal apps whose screens are largely the same.
It does not remove the second store listing, the second test pass, or the occasional piece of platform-specific code. A shared framework also does not guarantee that a later feature, such as a complex camera flow or a deep system integration, will stay comfortable.
A reasonable way to decide
Prefer a shared codebase when:
- The first release must reach both platforms together
- The main screens and tasks are the same
- Device-specific behavior is a small part of the scope
Prefer native when:
- The product depends on platform behavior, performance, or a long life on one operating system
- You already have a healthy native codebase
- The Android and iOS products are intentionally different
If you are unsure, decide after the feature list exists. Choosing the framework first tends to bend the product around the tool.
Testing does not disappear
Whichever route you take, the critical journeys still need to be tried on the Android versions and iOS versions you agreed to support. A single simulator run is not a release check.
Teramob covers both routes: native Android, native iOS, and cross-platform development. The recommendation should follow the product, and it should be written down before the build starts.
