Mobile App Development: Native, Cross-Platform or PWA?

The mobile decision is usually made on instinct and regretted on budget. Two fully native apps cost roughly twice one cross-platform app to build and considerably more than twice to maintain, because every change happens twice. That premium is sometimes worth paying. Often it is not.

Start with what the app touches

Work through the hardware and platform features the app genuinely needs: camera, GPS, offline storage, push notifications, biometrics, Bluetooth, background location. Cross-platform frameworks handle all of these competently today. The cases that still argue for native are narrow: heavy real-time graphics, intensive on-device processing, or deep integration with a platform capability that ships new each year.

Flutter and React Native in practice

Flutter draws its own interface, which gives you pixel-identical results on both platforms and excellent animation performance. React Native uses the platform components, so apps feel more native to each system and existing React developers can move across. If your team already writes React, that continuity is worth real money. If not, Flutter tends to produce fewer platform-specific surprises.

"An app nobody installs is worse than a website nobody bookmarks. Decide why someone would put your icon on their home screen before deciding how to build it."

When a progressive web app is enough

If the app is essentially a logged-in interface over your data, a progressive web app avoids both app stores entirely. It installs to the home screen, works offline with a service worker, and updates the moment you deploy without waiting for review. For internal tools and B2B portals this is frequently the correct answer, and it is the cheapest of the four to maintain.

The limits are real, though: push notification support and hardware access are weaker on iOS, and you lose app store discovery. If your growth depends on store search, that settles it.

Budget for the part after launch

Both stores change their requirements every year, and an app that is not updated will eventually stop being accepted. Plan for at least one maintenance release a year purely for platform compliance, separate from any new features. Teams that skip this discover it when the app is pulled.
