How Much Does a Mobile App Cost in 2026?

Building a mobile app in the Hungarian market in 2026 typically starts between €10,000 and €20,000 for a first, narrower version, a mid complexity app lands between €20,000 and €38,000, and complex systems with many integrations run above €38,000. On top of that comes yearly maintenance, which is 15 to 25 percent of the one time build cost. These are nearshore rates, which is exactly why many Western European and US companies build with Hungarian teams. Below we break the numbers down item by item.

Price bands by project type

Project	Typical scope	Price band
MVP, first version	1 core flow, simple backend, 1 admin screen	€10,000 to €20,000
Mid complexity app	sign up, payments, notifications, multi screen flows	€20,000 to €38,000
Complex app	real time features, several system integrations, extensive admin	above €38,000
Yearly maintenance	bug fixes, OS update tracking, small improvements	15 to 25% of the build cost

The bands cover both platforms (iOS and Android) built with cross platform technology. More on that shortly, because it is one of the biggest price drivers.

Where does the price come from?

Mobile app development cost is essentially hours multiplied by an hourly rate. Hungarian agency rates run between €30 and €65 per hour, and one developer’s monthly capacity is roughly 160 hours. A four month project that partly ties up two developers, a designer, and a project lead simply cannot come out of €5,000 by the math. Anyone quoting that number is either selling a template as custom work, or will price in what the quote left out once the project is underway.

The hours break down roughly like this on an average project:

Specification and planning: 10 to 15 percent. This is where we decide what to build. Skipping it is the most expensive saving of all.
UI/UX design: 10 to 20 percent, depending on how bespoke it needs to be.
Development (app plus backend): 50 to 60 percent. The backend is often a bigger job than the app itself, because that is where data handling, permissions, and integrations live.
Testing and release: 10 to 15 percent. Two stores, two review processes, checks across dozens of devices.

The six factors that move the price most

Number of platforms and the technology. Separate native iOS and Android development means writing and maintaining almost twice the code. With a cross platform framework (we use Flutter) both apps come from one codebase, which cuts the total cost by 30 to 40 percent. More on the technology choice in our separate article: native, hybrid, or web app.
Backend and data handling. An offline calculator app barely needs a server. A booking system needs user management, a database, and an admin interface.
Integrations. Card payment, invoicing software, an existing company system: each one is measured in weeks of work.
Design ambition. A custom, brand designed interface versus a correct but simple UI built from system components.
Login and permissions. As soon as there are multiple roles (guest, customer, admin), the number of cases to test jumps.
Notifications, real time features. Push messages, chat, live status tracking: all useful, all separate development line items.

Hidden and recurring costs

Many quotes do not flag these, yet they come back year after year:

Developer accounts: the Apple Developer Program is $99 a year, the Google Play Console is a one time $25.
Server cost: depending on load, €25 to €250 a month for an average Hungarian app.
OS update tracking: Apple and Google release a new system version every year, and occasionally mandatory technical requirements too (new API levels, privacy declarations). This is the biggest item in the maintenance fee.
Store administration: privacy labels, tester access, version management.

Where to save wisely, and where not to

Wise saving: start with a narrower first version. The MVP approach is built exactly for this, and in our experience a third to a half of the first feature list can safely be dropped from round one. Cross platform technology and using proven third party services (for payments, notifications, analytics) instead of building your own also save a lot.

Bad saving: cutting the specification and the testing. Both come back to bite you in the same place, near the end of the project, when the misunderstandings and bugs surface and fixing them is most expensive.

At ZNiTech every quote comes with a feature by feature breakdown. As a client you see exactly what each screen and each integration costs, so when the budget needs trimming it is not haggling, it is us crossing items off the list together.

Frequently asked questions

How much does a simple mobile app cost? A narrow feature set built properly runs between €10,000 and €20,000 for both platforms. Below that, ask what was left out: backend, admin interface, testing, or the release.

What monthly cost should I plan for after launch? Server, developer accounts, and maintenance together come to €100 to €400 a month for an average app, depending on usage.

Is a no code app builder not cheaper? For a simple internal tool it can work. For a customer facing app with a bespoke experience or real integrations, the limits of no code show up fast, and the platform fee can cost more over a few years than a custom build. Ownership is also a question: your no code app lives on the provider’s platform.

Why do I get such different quotes for the same app? Because they are not quoting the same thing. One quote includes the specification, the backend, the admin, and testing, the other only the app screens. Ask for a feature by feature breakdown and the differences become explainable immediately.
