How much does it cost to have a good app developed?

Behind every ballpark figure is a different product

When we talk to teams that want to “have an app built”, it often starts with one sentence: “We need a ballpark figure first.” And then the confusion follows: The first quote is €12,000, the next is €80,000, and somewhere on the internet it says “from €5,000”.

The reason is rarely a rip-off – it’s the cost black box, which arises when different people have different products in mind.

An app is not a single thing

“App” can mean: a small, installable information app without a login. Or a customer platform with accounts, payment processing, push notifications, an admin panel and integration with your existing system. These are two completely different structures.

We like to use an image internally: You can build “a house” – as a tiny house or as an apartment building with an underground garage. Both are called a house. Both have doors. But the price has no common language.

Misconception number one: Features don’t simply add up

Many people believe functions are like Lego bricks: One more, a little more expensive. In practice, features connect with each other. A login suddenly involves permissions, data protection, error messages, email flows, password reset, analytics and support.

Our Method 1: The Three-Question Translation

To make quotes comparable, we first translate every idea into three questions:

1) How many user flows are truly critical? (e.g. “Search”, “Book”, “Pay”)

2) How much data logic is behind it? (Backend yes/no, synchronization, roles)

3) How high is your risk, if something goes wrong? (Security, availability, liability)

When these three answers are clear, “app” becomes a project. And then the price suddenly becomes explainable – as a range, not a mystery.

By the way: We often see teams optimize “cheaply” too early out of fear of the budget. This rarely leads to lower costs, but rather to more iterations. The good news: These very iterations can be avoided if you invest in clarity first – not code.

As a rough guide: International benchmarks cite $5,000–50,000 for simple apps, $50,000–120,000 for medium-sized ones, and $120,000–300,000+ for complex ones. Business of Apps (2025)↗

Good planning works with ranges and assumptions

“How much does a good app cost?” can be answered most honestly like this: In ranges, not exact figures – and always including context.

If you have a professional development team in the DACH region, in practice we see three typical categories. An experienced app developer from the German-speaking region gives rough guidelines of around €20,000–45,000 for simple apps, €45,000–110,000 for medium-sized ones, and €110,000–300,000+ for complex enterprise apps. app-entwicklerin.de (Schulte, 2025)↗

These figures seem high compared to “from €5,000”, but they often fit better with what most people really mean when they say “a good app”: well designed, stable, secure, maintainable.

A few tangible examples

A “simple app” for us is rarely a fantasy app, but rather something like: displaying content, a few interactions, perhaps a form – without a custom backend. Here, a small scope can certainly fall in the range of around 20–45k if design, clean implementation, and the release process are included.

A “medium-sized app” usually has login, roles, an admin interface, or its own backend. This is exactly where many purpose-driven projects land: community, booking, educational content, donation or appointment logic.

It becomes “complex” as soon as you need several apps at the same time (e.g. user app plus admin plus service provider app), offline synchronization, or high security requirements. With platform ideas (“like Uber, but for …”), it quickly becomes a six-figure reality. For Uber-like systems, $50,000–150,000 per platform alone is often cited – and that is only the beginning when considering the entire system. mobian.studio↗

Region and team change the number – not the physics

International hourly rates vary widely (less expensive regions are significantly lower, senior teams in Europe/USA significantly higher). But the physics remains: Time for design, development, and testing does not disappear just because the hourly rate is lower.

What we want you to take away: Set a goal for the first version first. Then look for the appropriate range. Not the other way around.

And one more reality check from the startup magazine: A study cites average app costs of around €30,000 and amortization after about 12 months. StartingUp.de↗

Quality shows in stability and further development

You rarely recognize a good app by the fact that it “can do a lot”. You recognize it by the fact that it is calm : It feels clear, it doesn’t crash, it responds quickly, it protects data – and you can continue developing it a year from now without having to rebuild everything.

Quality costs – and almost always saves later

We see “good” as a mix of four things: UX, stability, security and future-proofing.

UX doesn’t just mean “beautiful”, but: You understand what to do without thinking. That’s exactly why many teams invest more in design than they initially expect. In budget breakdowns, we often see around 20–25 % for design – not as a luxury, but as part of risk reduction. Business of Apps (2025)↗

Stability means: The app runs on real devices, with shaky networks, with empty batteries, with people who tap “weirdly”. This is the moment when testing suddenly stops being a side issue. Here too, industry analyses often cite a 10–15 % budget share for testing and deployment. Business of Apps (2025)↗

Security is not just an issue for banks. Even a simple user account brings responsibility with it. We find that “cheap” offers often cut costs precisely here – not out of bad intentions, but because security work is difficult to make visible.

Future-proofing is our quiet favorite. It comes from good architecture, clean documentation and decisions that enable maintenance. That sounds unromantic, but it is exactly what turns a one-off project into a long-lasting product.

Fresh perspective 1: Good apps aren’t “built”, they’re “managed”

The biggest misconception is launch fixation. An app isn’t finished when it’s in the store. A good app has a plan for the next releases, a measurement logic (analytics) and a clear picture of which user problems it will solve next.

This perspective also changes the budget question: You don’t just ask “How much does version 1 cost?”, but “What does it cost to stay good for 12 months?” That’s exactly where quality begins for us – and exactly where “works somehow” and “really works” part ways.

If you think in this direction, the budget doesn’t get smaller, but more meaningful. And suddenly it’s much easier to explain internally or to investors why you’re not just buying code, but reliability.

The nature of a feature determines its effort

When we explain budgets, we never try to justify costs. We make them visible. And they become visible where you make decisions.

Feature Reality Instead of Feature List

The strongest driver is almost always the scope of functionality – but not as a number, rather as the type of functions. A calendar is not automatically expensive. It becomes expensive when the calendar can make bookings, manage capacities, handle cancellations, trigger invoices, and communicate with an existing system.

The backend is the classic surprise cost item. Many people only see the app on the phone. But as soon as user accounts, data synchronization, push notifications, or admin functions come into play, you are building a second product in the background: APIs, database, permissions, monitoring.

Integrations drive costs particularly reliably: payment providers, CRM, membership systems, maps, email, identity providers. Every integration is not just “connecting”, but testing, securing, and defining error cases.

Offline, Security, Device Functions: The Hidden Multipliers

Offline capability sounds small, but is often a multiplier: local storage, conflict resolution during sync, data migration. The same applies to sensitive data: health or financial relevance means more security effort.

And then there are the device functions: camera, Bluetooth, sensors, real-time location. Everything that is “close” to the device requires more testing on real devices.

Our Method 2: The “Three-Layer Scope”

To make planning calmer, we divide features into three layers:

1) Must: Without this, there is no benefit.

2) Proof: This proves the added value (often 1–2 functions).

3) Polish: This makes it feel complete (animations, convenience, extras).

We develop Must and Proof first and deliberately keep Polish flexible. This is not a cost-saving measure for its own sake, but a decision against budget surprises.

Fresh Perspective 2: Not “What is possible?”, but “What is provable?”

When you build an app to create impact – more access to learning, less waste, better care – then what counts is what you can actually demonstrate in the first version. This way of thinking shifts your budget from “everything once” to “get the most important thing right”.

That is how the good app does not become the most expensive one. Instead, it becomes the one that shows faster why it exists.

Budget Follows a Process, Not Just Features

An app looks like a product from the outside. Inside, it is a process with clear phases. If you understand, where money typically flows, you can read proposals much better – and quickly recognize whether someone is planning realistically.

We often see the following logic: First comes discovery (goal, users, scope, technical direction). Then comes UX/UI design (flows, prototype, visual language). Then development (frontend and backend), testing and launch.

Industry analyses show that companies often spend 10–20 % on discovery and around 20–25 % on design. Business of Apps (2025)↗ Development is usually the largest block, while testing and deployment often account for 10–15 %. Business of Apps (2025)↗

What does that mean for you in practice?

If an offer almost leaves out discovery and design, it seems cheaper at first glance. In reality, you often pay later – through rework, changes in direction, or a product that is technically „finished“ but fails to convince users.

Purpose projects in particular often face a special challenge: The app should not only work, but also earn trust. That comes from clarity and accessibility. This requires time in design and testing.

A small, honest mini-calculation

Let’s take a medium-sized app. If you think in terms of a total budget of €60,000, then €6,000–12,000 for discovery is not „overhead“, but insurance against false assumptions. And €12,000–15,000 for design is often the difference between „I’ll use it once“ and „I’ll stick with it“.

Fresh perspective 3: Discovery is the cheapest form of courage.

Many teams want to „get started quickly“ because the idea is pressing. We understand that. But from experience, the fastest route to launch is often the one that pauses briefly and describes the project in a way that makes it buildable.

If you want to read more about the approach to digital projects: In our „Momentum“ plan, we describe how we work from idea to operation.

Technology distributes costs over the entire lifecycle

The platform question often feels like a matter of faith: iOS first? Android? Both? Or go straight for a PWA?

We don’t solve this with dogmas, but with a simple observation: Technology is a form of cost over time. Not only when building, but when maintaining.

Native, Cross-Platform, PWA: what you’re really buying

Native development (two codebases) can make sense if you have extremely platform-specific requirements or if performance is truly critical.

Cross-platform (e.g. Flutter), on the other hand, can bring a great deal of efficiency because large parts of the logic are built once. A DACH source cites as a practical figure that Flutter can be up to 40 % cheaper than two native apps. app-entwicklerin.de (Schulte, 2025)↗

PWAs can be an honest alternative for certain use cases, especially if your product is more service- or content-heavy and you want to iterate quickly. They are not “better” or “worse”, but they change the cost structure: often cheaper to get started, sometimes limited when it comes to device features.

Hourly rate is not the same as price

International benchmarks show extreme differences in hourly and salary levels. Business of Apps (2025)↗ This explains why offshore offers can be significantly lower. At the same time, coordination, quality control, and the risk of misunderstandings often increase. We say this without drama: It can work well – but it is a project in its own right that should be factored into the calculation.

Our decision framework

If you need a fast time to market and the app does not have exotic hardware features, we often tend to recommend cross-platform.

If you need maximum integration and very specific platform UX, native can make sense.

If you first want to prove impact and your product is more of a “digital service”, we take a serious look at a PWA – especially because it allows you to learn faster.

For an introduction to PWA strategies, we recommend this overview as a good starting point: Google Web.dev on PWAs.

In the end, the technology question is rarely technical. It is strategic: Do you want to learn faster, grow faster or start as perfectly as possible ? Your budget follows this decision.

The second year belongs in the initial calculation

We see it again and again: A team budgets €60,000 for development – and €0 for the year after. That is human. But it is also the moment when good apps suddenly seem “too expensive”, even though only the wrong part was planned.

The real work begins after launch

New iOS and Android versions are released regularly, devices change, and libraries receive security updates. Then there are things you only learn after real users: Where do they drop off? What do they not understand? Which feature is used surprisingly often?

For maintenance and further development, experienced practitioners often cite a guideline of around 15–20 % of the original development costs per year. app-entwicklerin.de (Schulte, 2025)↗

This does not mean that you pay “that much again” every year. It means: You consciously plan time for stability, small improvements, adjustments, and security.

Operating costs are rarely the problem – surprises are

In addition, there is infrastructure: servers, database, email, push services, and possibly external APIs. Sometimes that’s a few dozen euros a month, sometimes significantly more – depending on how data-intensive your product is.

And yes: app stores cost money too. Apple charges an annual fee for the Developer Program, Google a one-time registration fee. These aren’t huge expenses, but they are part of “keeping it alive”.

Our perspective as a sustainable digital agency

Here’s a perspective we miss in many cost articles: Performance isn’t just UX, it’s also operating costs. If you develop efficiently, transfer less data, and use clean media, infrastructure and maintenance pressure decrease. For us, that’s “Green Design” in everyday life: not moralistic, but practical.

That’s why we plan early how the app can be updated later, what logging and monitoring will look like, and how you can avoid ending up locked into a tool. This may not be the most exciting chapter – but it’s the chapter that saves money in the long run and protects trust.

If you want to read up on analytics and crash reporting: Firebase Crashlytics is a good starting point for spotting errors early and making maintenance more predictable.

Value comes from a clear business task

Costs are only half the truth. The other half is: What are you actually paying for? And how do you know whether it’s worth it?

We’ve had good experiences with not treating ROI as a grand business theory, but as a simple, human question: “What change should this app bring about in everyday life?” When that’s clear, economic viability suddenly becomes concrete.

Three types of return we see in projects

First: Direct revenue (subscription, in-app purchases, transactions). Second: indirect revenue (more repeat purchases, better retention, the app as a reliable touchpoint). Third: Cost savings (less manual work, less support, fewer errors).

A study in the startup magazine reports that apps generate profits on average after about 12 months. StartingUp.de↗ We’re happy to take that as encouragement – while saying at the same time: That’s an average, not a promise.

Our practical ROI method: the 3-number story

To keep it from remaining nebulous, we work with three numbers that you can usually name even before the first line of code:

1) How often does the “core moment” happen per month? (order, booking, donation, usage)

2) What is it worth – in money or time? (contribution margin, minutes saved)

3) How many months do you give the app to learn?

A typical example from SME realities: If an app replaces 30 phone calls with self-service every week, it can quickly save a noticeable amount of working time. With internal apps, ROI is often clearest because you can see the time directly.

For Purpose Brands, there is a fourth return

In organizations with a mission, something else comes into play: Impact. If your app means that more people gain access, fewer resources are consumed, or donations flow more regularly, then “return” is not just euros.

This changes how we look at costs: We don’t just assess “cheap vs. expensive”, but “impact per euro invested”. And often, a solid, well-tested app is the cheaper decision here – because it earns trust and therefore gets used in the first place.

Sensible architecture prevents digital wear and tear

When we at Pola talk about costs, we never talk only about “how cheap can it be”. We talk about how useful does it remain.

Sustainability is a cost profile, not a sticker

An app can consume resources: data transmission, computing power, unnecessarily heavy media, constantly new device requirements. For us, developing more sustainably above all means: taking performance seriously, avoiding unnecessary complexity, and choosing technology so that it remains maintainable for a long time.

That sounds like “more effort” – and yes, sometimes good planning costs a little more at the beginning. But in operation, we often see the opposite effect: Fewer failures, fewer frantic fixes, fewer infrastructure surprises. That’s exactly why sustainability fits so well with the budget question: It makes costs more stable.

Inclusion is not an extra feature

Accessibility is surprisingly often only discovered at the end when it comes to apps. Then it gets expensive because you have to fix UI decisions backwards. If, on the other hand, you plan early with screen reader use, sufficient contrasts, understandable language, and clear focus orders, the additional effort remains manageable.

For Purpose Brands, this is not just “nice” – it is part of the attitude: access for everyone. And from a purely economic perspective, you reach more people this way and reduce support effort because fewer users get stuck on barriers.

Fresh perspective 4: Quality as social responsibility

We believe that software is not neutral. An unstable app doesn’t just cost money, it costs trust – and sometimes real opportunities, for example when people depend on help or need information.

That’s why we build quality not as “premium”, but as a standard. And we talk openly about what that means for the budget.

If you want to roughly follow best practices: The OWASP Mobile Security Testing Guide helps make security requirements more tangible – also for non-technical people who want to evaluate proposals.

A good MVP first proves the central thesis

Reducing costs often sounds like “less quality”. In our projects, it is more like: less ambiguity.

MVP is not small, but focused

An MVP is not a half-finished app. It is the first version that proves a thesis. If you have a budget limit, then the MVP is not a compromise, but the professional way to reduce risk.

For this, we like to start with a very concrete goal: “In 8 weeks, a real user should successfully go through the core moment once.” Not “everything finished”, but “the most important path without stumbling”.

Use standard services wisely

A common misconception: Either “build everything yourself” or “use a builder”. In between lies the good middle ground: use services where they save time, but design the architecture so that you are not trapped later.

For auth, push or crash reporting, platforms like Firebase are often a pragmatic starting point – as long as it is clear what ongoing costs arise and which data flows where.

Scope management without frustration

We try not to fight changes, but to sort them. Because in almost every project, you learn something new along the way.

For this, we use a simple rule: If something new comes in, something else has to go out or be pushed back. This keeps budget and time honest.

And we test early. Not “at the end”. Because errors that are discovered late are expensive – not only financially, but mentally.

Finally, a sentence we often say when things get tight: Don’t save on thinking. Save on what’s unnecessary.

Risks and assumptions belong next to the price

If you put two proposals side by side, the most expensive question is not “why so much”, but: What exactly is it for?

Fixed price or Time Material

A fixed price feels safe. But it only works if scope and assumptions are truly stable. Otherwise, the price contains a risk buffer – or the project ends in discussions about change requests.

Time and Materials (billing based on effort) can be fairer if you are still learning and priorities are shifting. However, you then need good transparency: What was done, what comes next, how much budget is still available.

Three things we always look for in proposals

First: Is there a clear description of the first version – ideally as user flows, not buzzwords.

Second: Are design, testing and release explicitly planned. If testing is missing, it is not “free”, it is just invisible.

Third: How are operations and maintenance considered. An app without a plan for updates is like a shop without a key.

A tip from experience: “Cheap” can mean that you have no freedom later

Pay attention to who owns the code, whether you receive documentation and whether the technology was chosen in a comprehensible way. We prefer sustainable, maintainable technologies and open standards because they reduce the likelihood that you will be back at square one after a year.

If you do not have a technical person on your team, a small counter-question can help in the conversation: “What are the two biggest risks in this project – and how are you planning for them?” The answer often says more than any price table.

And if you want to see references: Do not just look at “pretty screens”, but ask about what matters in everyday use: stability, further development, collaboration.

In Pola projects, we use transparency in tools and processes for this – including a central workspace for tickets, status and decisions. This is not an extra. It is a form of fairness: You should be able to understand at any time what you are paying for.
