One of the first decisions in any mobile project is how to build it. The options are often argued about like sports teams. They're better treated as tools with different strengths — and the right choice depends far more on your product and your plans than on which technology is fashionable.

Native

Separate apps written for iOS and Android using each platform's own languages and tools. You get the deepest access to device features, the best performance for demanding work, and the most platform-true feel. New operating system features are available on day one.

The cost is two codebases, usually two sets of specialists, and every feature built twice. For products where the mobile experience is the whole business — or where hardware access is central — that cost is often worth paying.

Cross-platform

One shared codebase that produces real apps for both stores, using frameworks such as React Native or Flutter, with native modules written where a feature needs them. For most business apps — bookings, ordering, accounts, content, dashboards — it delivers a high-quality experience with one team moving faster.

The trade-offs are a small dependency on the framework keeping up with platform changes, and occasional extra work for features the framework doesn't cover. Well-built cross-platform apps are hard to tell apart from native ones in everyday use.

Web app (PWA)

A progressive web app is a website that can be installed on the home screen, work offline and send notifications on supported platforms. There's no store review, updates are instant, and it can share a codebase with your existing website.

The limits: more restricted access to device features, less consistent behaviour across platforms, and no presence in the app stores — which matters if your customers expect to find you there. For internal tools, simple ordering or content products, it can be the fastest and cheapest route.

Questions that decide it

  • Do you need demanding device features — advanced camera work, Bluetooth hardware, heavy background processing?
  • Must you launch on both platforms at once, with one budget?
  • Does being in the app stores matter to your customers, or to how you'll be found?
  • How often will the product change in the first year?
  • Who will maintain it afterwards, and what skills does your team already have?

A simple rule of thumb

  • Hardware-heavy or performance-critical product → native.
  • Business app on both platforms, evolving quickly → cross-platform.
  • Content or internal tool, speed and budget first → web app.

The rule bends for specific cases, but it's a good place to start the conversation.

You're not locked in forever

Many successful products started as a web app to prove demand, moved to cross-platform when the audience grew, and rewrote a single demanding feature natively later. What matters most is that your backend and data are designed cleanly, because they outlive whichever front end you choose first.

Pick the option that gets real users to real value soonest. You can change the engine later; you can't get back the months.
