App development costs
Costs vary with project scope, features, complexity, technology and platform. Here are the ranges you can plan with, and the factors that drive the price.
Cost overview
Simple apps
€15,000 to €50,000
Clearly defined scope, one platform, manageable integrations.
Mid-complexity apps
€50,000 to €100,000
Several features, a backend, possibly both platforms and external interfaces.
Complex apps
from €100,000
Extensive logic, high security and scalability requirements, deep integrations.
These price ranges are a rough guide. We clarify the exact scope in the first conversation.
Any honest number before the first conversation is a range. Anyone who names a fixed price without knowing your project is building in buffers — at your expense. What we can firmly promise is the path there: in a Discovery for €1,900 we capture your project, sharpen the scope, and you get a binding fixed-price quote. The amount is credited when you place the order. For large, complex apps this becomes a deeper concept sprint.

Examples
A capture app for a team
€15,000 – €50,000
One clear purpose (e.g. receipts, delivery notes, documentation), one platform, few interfaces.
Keeps the price low: tight scope, one platform.
A field-service app with offline mode
€50,000 – €100,000
Working without a connection, syncing once online, a backend with user management.
Drives the price up: offline data storage and conflict resolution on sync.
A customer app with accounts and system integration
from €100,000
Login and personal data, integration with existing systems, usually iOS and Android.
Drives the price up: security, interfaces, two platforms.
Ballparks from typical projects of this kind — yours may land below or above it. The cost estimator narrows it down further.
Cost factors
Wireframes, prototypes and UI design with audience analysis and test phases. Good UX drives usage and ratings.
Native (iOS/Android) or cross-platform. Native is usually more expensive but more performant; modern frameworks are closing the gap.
Servers, data storage and interfaces are needed for most apps and add to the effort, with scaling in mind.
After launch: upkeep, security and OS updates, new features. Ongoing costs that keep things stable.
After launch
Apple Developer Program US$99 a year, Google Play a one-off US$25. Without the accounts there is no publication — and with Apple, no yearly renewal without the fee.
Hosting, monitoring, bug fixing and the yearly OS updates from Apple and Google. A common industry rule of thumb is 15–20 % of the development cost per year.
New features based on user feedback — plannable in stages and not a must from day one. Budget it after the first quarter of operation, when real usage data is in.

FAQ
Simple apps start at around €15,000 to €50,000, mid-complexity ones at €50,000 to €100,000, and complex ones from €100,000. The ranges are a rough guide; we clarify the exact price in conversation.
Scope of features, platform choice, backend needs and maintenance all have a strong effect on the price. A simple app involves far less effort than a complex enterprise application.
Cross-platform is often more cost-effective, native usually more performant. Modern frameworks like Kotlin Multiplatform increasingly combine both.
Store accounts (Apple US$99 a year, Google Play a one-off US$25), hosting, and maintenance including the yearly OS updates. As a rule of thumb, 15–20 % of the development cost per year is budgeted for upkeep and operation.
