When you decide to build a mobile app, one of the first questions is whether to build two separate native apps or one cross-platform app. Neither is always better. The right choice depends on what your app does.
What the terms mean
- Native apps are built separately for iPhone (Swift) and Android (Kotlin), using each platform's own tools.
- Cross-platform apps share most of one codebase across both platforms, using frameworks such as Flutter or React Native.
When cross-platform is a good fit
- Ordering, booking, loyalty, content and account-based apps
- A limited budget or a need to launch on both platforms quickly
- A small team that must maintain one codebase
When native is worth it
- Graphics-heavy games or advanced animation
- Deep use of device features such as specialised sensors or background processing
- A product where the last bit of performance defines the experience
Comparing the two
- Cost: cross-platform is usually lower because you build the interface once.
- Speed to market: cross-platform is usually faster.
- Performance: native has an edge in demanding cases; for most business apps the difference is not noticeable.
- Maintenance: one shared codebase means fewer places for bugs to hide.
Do not forget the backend
Whichever you choose, most apps also need a backend for accounts, data and payments, plus an admin area to manage content and orders. Plan and budget for it from the start.
Our advice
For most business apps, we recommend starting with cross-platform and a focused first release, then learning from real users. See our mobile app development service or get in touch to talk through your idea.
