iOS app development: cost and process at a glance

You want an iOS app built and you're wondering what it costs and how it works? Short answer: a lean MVP app for the iPhone starts at around €7,900 with us, a full-blown business app at €14,900 (usually for iOS and Android at the same time at that point). On top of that there's about €99 per year for the Apple Developer Program and maintenance from €149/month. From the first idea to App Store approval, expect six to sixteen weeks depending on scope. Let's look at the details — so you know what you're getting into.

When an iOS-only app makes sense

Not every app has to run on iPhone and Android from day one. An iOS-only app is the right call if one of these situations applies to you:

• Your audience skews Apple. In Germany the iOS share sits somewhere between 35 and 45 percent depending on the industry — but in the premium segment, with younger, higher-spending audiences or certain B2B users, iPhones are clearly in the majority. If nearly all your customers carry an iPhone, Android is dead weight for now.
• You want to start lean. One platform means less testing, fewer device variants, lower cost. Especially for a first attempt, that's often smarter than serving both worlds half-heartedly.
• You use Apple tech deeply. Face ID, Apple Pay, Apple Wallet, HealthKit, Live Activities on the lock screen, widgets — if you're really making the most of these, iOS is home.
• Your budget is limited. One platform costs noticeably less than two. You can start with iOS and add Android later, once the app has proven itself.

The flip side: if you want to reach a broad audience from the start — say a consumer app that everyone should have — there's barely a way around Android. In that case it's worth looking at a cross-platform approach, which we'll get to in a moment.

Native development with SwiftUI — our strength on iOS

When we build an iOS-only app, we go with SwiftUI. That's Apple's modern framework for app interfaces — the official, native way to build iPhone apps. "Native" means the app talks directly to the operating system, with no layer in between. That brings three tangible advantages:

1. Best performance and the real iPhone feel. Animations, scrolling, gestures — everything feels the way iOS users expect. No "this isn't quite iPhone somehow" moments.
2. Immediate access to new Apple features. When Apple announces a new iOS feature in the fall, it's usable with SwiftUI on day one. Cross-platform frameworks often lag weeks behind here.
3. Full depth on device features. Camera, sensors, Face ID, push, background processing — natively you get direct, complete access everywhere.

Native (SwiftUI) or cross-platform?

The alternative to native is cross-platform — a framework like React Native or Flutter where you write the code once and run it on iOS and Android. The appeal: one codebase for both stores, noticeably cheaper if you need both platforms anyway.

The honest rule of thumb:

• Only iOS matters, high demands on performance and polish? Native with SwiftUI. The cross-platform cost advantage doesn't kick in at all if you're only building one platform — you're better off skipping the abstraction layer.
• iOS and Android on one budget, a classic business app? Cross-platform is usually the more economical choice.

We have no dogma here — we build both and tell you up front what fits your project. If you want to understand this fundamental decision more deeply, we've worked through it in detail in Native app or cross-platform.

What does an iPhone app cost? The concrete numbers

That's probably the question that brought you here. "What does an app cost?" can't be answered in one sentence — an app can be a lean companion or a full platform with its own server. Here are our honest ballpark figures:

A few things that move the price up or down:

• The feature set. An app that displays content and submits a form is cheaper than one with login, payments, map integration and live sync.
• The backend. Many people underestimate that the visible app is often only half the job. As soon as users sign in, data needs to sync across devices or push notifications go out, you need a server behind the scenes. We plan that backbone — usually on a Laravel foundation with us — from the start, so app and backend work together cleanly.
• The design. A standard look is built faster than a custom-designed, fully thought-through experience.

The running costs are manageable but real: the €99 a year for Apple, plus your maintenance. Why maintenance isn't optional luxury comes up in the Apple chapter in a moment. If you want to see the cost factors broken down in general — beyond iOS — you'll find that in detail in App development cost. And if you'd rather turn the dials yourself, the package configurator puts together a first ballpark, no strings attached.

The process: from idea to the App Store

Here's how an iOS project typically runs with us — transparent, in clear steps, so you always know where we stand.

1. Free initial call & concept. We listen to your idea, clarify the core feature and the target audience. By the end you know what's realistic — and you get an honest assessment of effort and cost.
2. Design & clickable prototype. Before a single line of code exists, we make the app visible: the most important screens and flows to click through. That way we catch thinking errors while they're still free to fix.
3. Development in stages. We build the app with SwiftUI and set up the backend in parallel. You regularly get test builds via TestFlight (Apple's official tool for beta testing) on your own iPhone — no guesswork, just actually trying it out.
4. Testing & polish. On different devices, with real data. We iron out bugs before Apple finds them.
5. Submission & Apple review. We set up your App Store listing — name, description, screenshots, privacy details — and submit the app for review.
6. Approval & launch. Once review passes, the app goes live. From here on, support begins: updates, new features, adjustments for new iOS versions.

The Apple review process — no reason to panic

Every app headed for the App Store is reviewed manually by Apple. That scares a lot of people beforehand, but in practice it's quite predictable. Review usually takes 24 to 48 hours. Among other things, Apple looks at:

• Stability — the app must not crash and has to work completely.
• Privacy — you have to correctly declare what data the app collects (the "app privacy" label). If required, you also need a "Sign in with Apple" option when you offer other social logins.
• Guideline compliance — no misleading claims, a clear purpose, and use of Apple's in-app purchases for digital sales.

What we see in our projects: if you think about Apple's guidelines from the start, you usually get through in the first or second round. That's exactly our job — we know the usual rejection reasons and build the app so it doesn't run into them in the first place.

What else you need to keep in mind with Apple

A few iOS-specific points that tend to get overlooked day to day:

• The Apple Developer Program is mandatory. Without the membership (€99 per year) you can neither test via TestFlight nor publish. Ideally the account is in your name or your company's — then the App Store listing belongs to you, not to the agency. We set that up together with you.
• Updates aren't optional extras. Apple ships a new iOS version every fall. New devices, new screen sizes, changed rules — all of that needs upkeep, otherwise the app ages and in the worst case eventually gets pulled from the store. That's why maintenance from €149 a month isn't an optional surcharge; it belongs to an app the way an inspection belongs to a car.
• Design expectations are high. iOS users have a fine sense for whether an app feels "right". Apple's Human Interface Guidelines are more than bureaucracy here — they're the reason native apps feel so natural to use.
• In-app purchases go through Apple. If you sell digital content or subscriptions in the app, that has to run through Apple's payment system — including the well-known commission. Physical goods and services are exempt. Knowing this early saves nasty surprises in your math later.

Bottom line: an iOS app with a clear plan instead of flying blind

Having an iPhone app built isn't a black box. Costs start at around €7,900 for an MVP, the path to the App Store is plannable, and the Apple review process is very manageable with the right preparation. What matters is that you know from the start what you're getting into — technically, budget-wise, and in terms of what comes after launch.

That's exactly what we're here for. We build native iOS apps with SwiftUI, plan the matching backend right along with them and stay with you into the store and beyond. What that looks like as a whole is laid out in our app development service.
