iOS App Development: What to Know Before You Build (and What It Costs)
iOS users spend more and expect more polish — and Apple reviews every app strictly. Here is what that means for your build, your timeline, and your budget.
iOS is a smaller share of devices than Android globally, but its users tend to spend more and expect a higher level of polish — which makes it a priority for many businesses, especially premium and paid apps.
Here is what building for iOS actually involves: the audience, Apple's stricter review, the native-vs-cross-platform choice, and the cost.
Why build for iOS first?
- Users spend more — iOS audiences historically convert and pay at higher rates.
- Higher expectations — the bar for design and smoothness is high; a rough app stands out badly.
- Cleaner target — fewer device and OS versions to support than Android.
- Premium markets — in many Western markets, iOS share among buyers is significant.
Native (Swift) or cross-platform?
Native (Swift/SwiftUI) gives the best possible performance and platform feel, and day-one access to new Apple features — worth it for performance-critical or deeply iOS-integrated apps. Cross-platform (Flutter/React Native) builds iOS and Android together for meaningfully less, and is excellent for most business apps. See our native vs cross-platform guide to choose.
Cost and timeline
iOS app costs follow the same tiers as mobile apps generally — roughly €8,000–20,000 simple, €20,000–60,000 standard, €60,000+ complex — plus the €99/year Apple Developer account. A simple app takes 1–2 months; a standard one 3–5. For the full breakdown, see what a mobile app costs.
Key takeaways
- iOS audiences spend more and expect polish — good for premium and paid apps.
- Apple's App Store review is strict; design to the guidelines from the start.
- Native (Swift) for performance-critical apps; cross-platform covers most for less.
- Costs match the mobile-app tiers, plus €99/year for the Apple Developer account.
Frequently asked questions
Should I build for iOS or Android first?
It depends on your audience. If your buyers skew premium or Western, iOS often comes first. If reach or emerging markets matter more, Android does. Cross-platform lets you launch on both at once, which sidesteps the question for most businesses.
Why does Apple take a cut of in-app purchases?
For digital goods and subscriptions sold inside the app, Apple requires its in-app payment system and takes a commission. Physical goods and services are exempt. This shapes how you design monetisation, so plan for it early.
How long does App Store approval take?
Usually a day or two if you follow the guidelines, though it can be longer for complex apps or if changes are requested. The delay is rarely the review itself — it is fixing anything that breaks the rules.

A mobile app is not "a website you tap." It is two platforms, an app store gauntlet, and ongoing upkeep — which is why quotes run from €8,000 to €150,000+.

Cross-platform builds both apps from one codebase and usually costs less; native builds each separately for maximum polish. Here is when each is worth it.
