iOS agencies in Dortmund
A native iOS app uses Swift and Apple's own tools directly, drawing full performance, camera and sensor access, and new OS features out of the platform. That's especially worthwhile when your users are mostly on iPhone or the app depends on being close to the hardware. This list shows specialized iOS agencies, ranked by App Store experience, budget, and verified credentials.

Guide
When native iOS is the right choice
If your audience is almost exclusively on iPhone, for example with certain B2B or premium offerings, or if the app works closely with the camera, motion sensors, or new Apple features, native iOS delivers noticeable advantages over cross-platform approaches. If you need Android from the start as well, React Native with a single codebase can be more economical. An honest agency, the kind you'll also find among the app development agencies, discusses that trade-off before the proposal, not after. For business apps on company-owned devices managed through mobile device management, native iOS is often already the given choice too.
SwiftUI or UIKit
SwiftUI is Apple's declarative framework for interfaces, available since iOS 13, and today the right choice for most new projects. Older, long-running apps, though, often still run on the earlier UIKit or mix both. An agency experienced in both worlds can extend existing code cleanly instead of rewriting it from scratch with every change.
How to spot an experienced iOS agency
A look at apps already published in the App Store often reveals more than any portfolio PDF: reviews, update history, user numbers. Also ask who holds the Apple developer account. It should be registered to your company, not the agency, so you can switch providers if needed. And clarify the testing phase through TestFlight, which lets real users try new versions before release. It's also worth checking how the design follows Apple's Human Interface Guidelines, since deviations from them stand out negatively to iOS users faster than on other platforms.
What an iOS app costs
€110 to €190 per hour is standard for specialized iOS development in Germany. A simple app runs €18,000 to €35,000, an app with user accounts, offline features, and system integration €35,000 to €100,000. Complex apps with hardware integration or elaborate graphics start at €100,000. Beyond that, plan for another 15% to 20% of the development budget per year for maintenance and annual adjustments to new iOS versions. Ranking in the list follows the methodology score; use search to narrow further by budget, or submit a project request.
Frequently asked questions
iOS agencies: questions and answers
What does a native iOS app cost?
A simple app costs €18,000 to €35,000, an app with user accounts and system integration €35,000 to €100,000, and complex apps with hardware integration start at €100,000. Agencies typically charge €110 to €190 per hour for specialized iOS development.
Do I need SwiftUI, or is UIKit enough?
For new projects, SwiftUI is the standard today and usually the right choice. Existing, older apps, though, often still run on UIKit or combine both frameworks. An experienced agency decides based on your existing code, not personal preference.
How long does App Store review take?
Usually a few days, longer if issues come up. Apple checks every new version before release for policy compliance, including privacy, feature scope, and stability. Experienced agencies know the most common rejection reasons and plan buffer time accordingly.
Is native iOS worth it if I also need Android?
Usually not from the start: for two platforms at once, cross-platform approaches like React Native often save significant effort compared with two separate native apps. Native development pays off more once one platform clearly leads or you plan to build specialized teams per platform later anyway.
