If you're building your first business app, one question comes up before any other: iOS or Android first? Building both at once costs more, so most UK businesses sensibly start with one. This guide walks through the market share, cost, timeline and audience factors that should drive that decision — and gives you our straight recommendation.
Market Share: iOS vs Android UK
The UK is unusual. Globally, Android dominates with the large majority of devices — but in the UK specifically, iOS holds roughly half the market, and among higher-income and younger urban users its share is higher still.
This matters enormously. If you read global stats and conclude "Android first, obviously," you may be aiming at the wrong audience for a UK-focused business. The platform split among your customers is what counts — not the worldwide average.
Which Audience Uses Which
A few reliable patterns help you predict where your users are:
- Premium and consumer-facing brands in the UK often skew iOS, and iOS users tend to spend more per head in apps.
- Mass-market, budget-conscious or international audiences skew Android, which covers a far wider range of device prices.
- B2B and enterprise depends on the company — but bring-your-own-device workforces are genuinely mixed.
If you have any analytics already (your website's device breakdown is a great proxy), use them. Real data about your audience beats any general rule.
Cost Differences
Per platform, build costs are broadly comparable — but a few things tilt the balance:
- iOS has fewer device and OS combinations to support, which can make testing slightly cheaper and more predictable.
- Android must work across thousands of devices and screen sizes, so thorough testing takes more effort.
- Two native apps means roughly two builds — the main reason businesses start with one platform rather than both.
The headline: doing one platform well is far cheaper than doing two badly.
Development Timelines
A focused, well-scoped native app typically reaches the store within a couple of months of kick-off. Two factors affect the timeline most:
- App Store vs Google Play UK review: Google Play approval is usually faster and more automated; Apple's App Store review is stricter and occasionally sends builds back, so it pays to follow the guidelines closely from the start.
- Scope creep: the single biggest cause of delay. Ship a tight first version, then iterate.
Building for Both
If you genuinely need both platforms from day one, you have two routes:
React Native vs Native
Native (Swift/SwiftUI for iOS, Kotlin/Java for Android) gives the best performance, the smoothest feel, and first access to new platform features. The cost is two codebases.
Cross-Platform Alternatives
Cross-platform frameworks like React Native or Flutter let you share most of one codebase across both platforms, which can cut the cost of "both" significantly. The trade-off is some loss of native polish and occasional friction with platform-specific features.
A good rule of thumb: choose native when performance, animation and platform integration are central to the experience; choose cross-platform when you need both platforms quickly and the app is more content- and form-driven.
Our Recommendation
For most UK businesses launching their first app, we recommend:
- Check your own audience data first. Your website's iOS/Android split is the single best signal.
- If you're a UK consumer brand with no data, lean iOS first — UK iOS share is high and iOS users monetise well.
- If you're targeting the widest possible reach or a budget-conscious/international audience, lean Android first.
- Pick one, ship it, learn from real users, then expand to the second platform — using cross-platform only if speed-to-both outweighs native polish.
The worst outcome is splitting a limited budget across two half-finished apps. Do one properly.

FAQ
Which is cheaper to build, iOS or Android? They're broadly similar per platform; Android can take a little more testing effort due to device variety. The real cost difference is one platform versus two.
Can I launch on both at the same time? Yes — either with two native apps or a single cross-platform build. Just be clear-eyed that "both" roughly doubles native effort, which is why phasing is popular.
Does iOS really lead in the UK? In the UK, iOS holds around half the market — far higher than its global share — which is why UK-focused consumer apps often start on iOS.
How long until my app is live? A focused native app typically reaches the store within two to three months of kick-off, depending on complexity.
