The short answer
It depends on what the app does. Published Irish cost guides typically put a simple business app in the region of several thousand euro, often €7,500 to €15,000, with complex apps costing much more. Some smaller Irish developers advertise starting prices from around €1,800 to €3,000.
What drives the cost of an app
- Number of platforms: building separate native apps for iPhone and Android roughly doubles the work. A cross-platform app uses one codebase for both.
- Features: user accounts, payments, bookings, chat and custom back-end systems all add time.
- Design: a custom design with lots of screens costs more than a clean, simple layout.
- Integrations: connecting to existing systems such as stock, booking or loyalty software adds work.
- Ongoing care: updates for new iOS and Android versions, hosting and support.
How ThinkX builds an app for €599
We build one cross-platform app for iPhone and Android from a single React-based codebase. Our in-house AI tools speed up the build, and an experienced developer supervises every project. For a focused, simple business app, that brings the price down to €599, fixed, for the scope we agree up front. See our €599 app offer.
When €599 isn't enough
If your app needs payments, user logins or a custom back end, it will cost more, and we'll tell you so honestly with a separate fixed quote before any work starts.
Other costs to budget for
- Apple and Google charge their own developer account fees, paid directly to them.
- If your app uses a server or database, there may be small monthly hosting costs.
- Updates and new features after launch are quoted separately.
