If you want an app on both Android and iOS you have two routes: build each one separately in its own language, or build once with a cross-platform framework and ship to both. The honest short answer is that cross-platform is the right default for most businesses and native is the right answer for a specific, identifiable minority.
What cross-platform actually saves
React Native and Flutter let one codebase produce both apps. The saving is real but it is not 50% — shared logic and UI are shared, while store setup, platform permissions, push notifications and release processes still have to be done twice. In practice, expect to pay somewhere around 60–70% of two native builds, and to maintain one codebase instead of two forever after, which is where the larger long-term saving sits.
When native is worth the extra
- Heavy graphics or real-time processingGames, video editing, augmented reality, live camera effects. The framework layer costs you frames you cannot afford.
- Deep platform integrationComplex widgets, Apple Watch or Wear OS companions, background location over long periods, or anything using an API the day it ships rather than the month the framework supports it.
- The app is the entire productIf your business is the app and it will be developed continuously for years by a full-time team, native's ceiling is higher and you will eventually reach the framework's.
The option to consider first
Before either: does it need to be an app at all? A fast, installable progressive web app costs a fraction, has no store review, updates instantly, and is often what a business actually needs. Users install apps they open weekly; a service people use twice a year does not survive on a home screen.
If the honest answer is that you want an app for credibility rather than use, a strong mobile website will serve you better and cost far less.
How we choose
Our default is React Native, because most business apps are forms, lists, payments and notifications, and that is exactly what it is good at. We move to Flutter when the interface is heavily custom, and to native when one of the three cases above applies.

Frequently asked questions
Is a React Native app slower than a native app?
For typical business apps — lists, forms, payments, notifications — the difference is not perceptible to users. It becomes perceptible in graphics-heavy work, continuous animation and real-time media processing. If your app is a catalogue and a checkout, this is not the deciding factor.
Can we start with one platform and add the other later?
Yes, and with a cross-platform codebase the second platform is mostly store setup and testing rather than a second build. If you start native, adding the second platform later is close to a second full project.
Will Apple and Google approve a cross-platform app?
Yes. Both stores are full of them, including apps from very large companies. Rejections are almost always about content, permissions or privacy disclosures, not about the framework.
