Platforms

App development cost by platform

Where your app runs changes what it costs — and not in the way most estimates suggest. The device and OS test matrix, the store release process and the platform-specific engineering are usually the difference between a cheap estimate and an honest one.

Like-for-like

The same app, priced on each platform alone

One controlled configuration — a standard app, six features, 24 screens, custom backend, baseline security — built for each platform as its only surface. That is the only way these figures are comparable.

Cost by platform for an identical app
Platform	Same app, priced here	Device configs	Test matrix	Typical stack
iOS	$230K – $320K	9	30 hrs	Swift, SwiftUI, UIKit
Android	$240K – $330K	24	64 hrs	Kotlin, Jetpack Compose
Cross-platform	$260K – $360K	26	74 hrs	React Native, Flutter, TypeScript, Dart
Web app	$230K – $320K	12	34 hrs	TypeScript, React, Next.js
Tablet	$240K – $330K	14	46 hrs	Swift, Kotlin, React Native
Desktop	$250K – $340K	10	54 hrs	Electron, Tauri, Swift, C#
Wearable	$220K – $300K	8	34 hrs	SwiftUI, WatchKit, Wear Compose
TV / OTT	$250K – $340K	16	88 hrs	tvOS, Android TV, Roku BrightScript

Those are single-surface figures. Combining platforms costs far less than adding them up: shared backend, data model, APIs and design system are built once, and each additional surface pays only for its own client build, store release and device matrix. React Native / Flutter collapses iOS and Android into one codebase entirely.
