The Real Cost of Building an iOS App

Why Cost Estimates Vary So Widely

Ask five developers for a quote and you'll get five very different numbers. That's because "build an app" can mean anything from a two-screen utility to a full social platform. The key is understanding what drives the cost so you can make informed decisions about scope.

The Main Cost Drivers

• Number of screens: Each screen needs design, build, and testing. A 5-screen app is dramatically cheaper than a 25-screen app.
• Backend complexity: Does your app need a server? User accounts? Real-time sync? A database? Each adds scope.
• Third-party integrations: Payment processing, maps, AI APIs, and analytics SDKs all add development and testing time.
• Design level: Using a template is fast. A bespoke design system with custom animations takes significantly longer.
• Platform features: Widgets, Apple Watch support, Live Activities, and Siri shortcuts each add meaningful scope.

Realistic Price Ranges

Here's what you can expect to pay a UK developer for a quality iOS app in 2026:

• Simple utility (3-5 screens, no backend): £3,000 – £8,000
• Standard app (8-15 screens, basic backend): £8,000 – £25,000
• Complex app (20+ screens, real-time, integrations): £25,000 – £60,000+

These ranges assume a solo developer or small team building production-quality code. Agency rates will be higher. For context on web pricing, see our guide on how much a website costs in the UK.

Ongoing Costs After Launch

Building the app is only part of the investment. Budget for:

• Apple Developer Program: £79/year — required to publish on the App Store
• Backend hosting: £0 – £200/month depending on user base and infrastructure
• Maintenance & updates: iOS updates, bug fixes, and new features — typically 10-20% of the initial build cost per year
• App Store fees: Apple takes 15-30% of in-app purchases and subscriptions

How to Keep Costs Down

• Start with an MVP: Ship the core feature first. Validate demand before building the rest.
• Use proven patterns: Standard navigation, system components, and familiar UI patterns are faster to build and test.
• Avoid premature features: Social sharing, dark mode, and multi-language support can wait until you have users.
• Be decisive: Changing direction mid-build is the #1 reason projects go over budget.

Getting an Accurate Quote

The best way to get a realistic estimate is to write a one-page brief covering: what the app does, who it's for, the must-have features for launch, and any integrations you need. A good developer will turn that into a detailed scope and fixed-price quote within a few days.
