What Drives Mobile App Development Cost? A Guide for Businesses

"How much does a mobile app cost?" is a lot like asking "how much does a house cost?" Until you know how many rooms it has, what it is built from and where the plot is, any number you hear is either too optimistic or more cautious than it needs to be. Mobile app pricing works the same way: it can't be discussed sensibly until it is clear what is being built.

This article is written for business owners and institutions thinking about commissioning an app. Instead of quoting figures, we explain what mobile app development cost actually depends on: which decisions grow the budget and which shrink it, which expenses continue after launch, and what to watch for when collecting quotes from mobile app development companies.

The main factors that drive cost#

The cost of an app is mostly the development effort that goes into it. The decisions that increase or reduce that effort fall under the headings below.

Platform: iOS, Android or both#

The first question is which devices the app will run on. Android-only or iOS-only app development is less work than targeting both platforms. But choosing a single platform without knowing which phones your audience uses can mean leaving part of them out from day one. For business apps, this decision is usually made by looking at the devices employees or customers actually carry.

Native or cross-platform?#

With native development, separate code is written for each platform: Swift for iOS, Kotlin for Android, for example. This gives direct access to everything the platform offers, but it means two codebases, and every feature is built twice and tested twice.

With cross-platform tools such as Flutter and React Native, a single codebase produces the app for both platforms. For most business apps, internal tools and content-driven apps, this approach noticeably reduces both development and maintenance cost. For apps that are graphics-heavy, push device hardware to its limits or need brand-new platform-specific features from day one, native development may be the better choice.

Number of screens and features#

The most direct indicator of cost is how many screens the app has and what those screens do. A screen that only displays information and one where the user enters, filters and edits data do not take the same effort. That is why the screen count should never be judged alone, but together with the business logic behind each screen.

Login, payments, notifications, maps, offline mode#

Some features sound simple but carry a serious workload behind them:

• User login: Email login, phone verification, sign in with Google or Apple, password reset and role-based permissions are each separate work items.
• Payments: In-app purchases, subscriptions or card payments require payment provider integration, refund scenarios and compliance with store rules.
• Notifications: Sending a notification is easy; sending the right content to the right person at the right time needs logic on the backend.
• Maps and location: Showing a location, drawing a route, listing nearby points or tracking location in the background are very different in complexity.
• Offline mode: An app that works without internet and syncs data once the connection returns needs a design for resolving conflicting changes. This is one of the most underestimated features.

Backend and admin panel#

The app the user sees is the tip of the iceberg. The server where data is stored, the API the app talks to and the panel that manages content often take at least as much effort as the mobile side. If nobody discusses up front who will manage products, users, orders or announcements, and from where, that need surfaces mid-project and changes the plan.

Integrations#

Will the app work on its own, or does it need to talk to your existing software, such as your ERP, accounting system, CRM or school management system? Each integration is a separate work item. If the other system has a well-documented API, things move quickly; if not, the data exchange has to be worked out first.

Design#

There is a real difference in effort between a clean interface built from ready-made components and a branded, animated interface shaped through user testing. Settling the design early reduces "let's redo this screen" rounds during development and lowers the total cost.

AI features#

AI features such as text summarisation, chat assistants, recognising products from images or personalised recommendations are requested more and more often. Their cost depends on whether an existing model service is used or a system is built on the organisation's own data. Hosted services create an operating expense that grows with usage, and that needs to be planned for from the start. If you are new to the topic, our article What Is Artificial Intelligence? is a good place to begin.

Security and data protection#

Any app that processes personal data should account for data protection obligations (in Turkey, the KVKK) from the design stage: which data is collected and why, where it is stored, who can access it and how it will be deleted. Encrypted data transfer, role-based authorisation and regular backups are not details to bolt on later; they are part of the architecture. In sensitive fields such as health, education or finance, this heading carries even more weight.

What do small, medium and large scopes look like?#

Scope can be described without quoting numbers. The three examples below represent projects that give different answers to the same question.

Small scope: An app that does one job and has a handful of screens. For example, an app that shows a business's product catalogue, includes a simple request form and has its content managed from a ready-made panel. There is no login or only a simple one, and no payments or integrations.

Medium scope: An app with user accounts, role-based permissions, notifications, a custom admin panel and one or two integrations. Booking, order tracking and field team apps usually fall into this group.

Large scope: Platforms where several user types (for example customers, couriers and businesses) work through separate interfaces, with payments, maps, offline mode, multiple integrations and AI features, and which need to scale to a large number of users.

As scope grows, it is not only development time that increases; testing, security and maintenance grow along with it.

Project stages: from discovery to maintenance#

A well-run mobile app project usually goes through five stages:

1. Discovery: It becomes clear who the app is for, which problem it solves, which features are essential in the first version and what can wait. Accurate pricing is only possible after this stage.
2. Prototype: Screens and user flows are prepared as a clickable mock-up. This is the cheapest way to catch misunderstandings before any code is written.
3. MVP: The first version that does the app's core job is built. An MVP is not a half-finished product; it is a product with fewer features that does its job properly.
4. Launch: Store accounts are opened and the app goes through App Store and Google Play review. Apps that don't follow store rules can be rejected, so this step belongs in the plan too.
5. Maintenance and development: New versions ship based on user feedback, bugs are fixed and the app is kept compatible with new operating system releases.

Costs that come after launch#

The items most often overlooked when comparing quotes are the expenses that continue once the app is live:

• Store accounts: Apple Developer Program membership is 99 US dollars per year (it may be shown in local currency depending on the region; nonprofits, accredited educational institutions and government entities can request a fee waiver under certain conditions). A Google Play developer account is opened with a one-time registration fee of 25 US dollars.
• Servers and services: Databases, file storage, notification services, maps and AI services are usually billed by usage. As the number of users grows, so does this expense.
• Maintenance: A regular maintenance budget should be set aside for bug fixes, security updates and small improvements.
• Operating system updates: Apple and Google release new operating system versions every year, and the stores gradually require apps to support them. An app that is never touched can, after a while, become impossible to update or disappear from the store.

Ways to reduce cost#

Keeping the budget under control isn't about cutting quality; it's about working in the right order:

• Start with an MVP: Build only the features that are the reason the app exists in the first version. Features added after you see what users actually want are both better targeted and cheaper.
• Choose cross-platform: For suitable projects, a single codebase is more economical than separate development and maintenance for two platforms.
• Use ready-made services: Mature services exist for authentication, notifications, payments and maps. Writing them from scratch rarely makes sense.
• Question whether you really need a mobile app: Some needs can be met with a web app that works smoothly on a phone. For example, the question-solving app we built for İspat College is web-based and mobile-friendly; students simply log in from a browser, with nothing to install. For institutions considering a similar custom study app, this approach removes both the store process and the maintenance load of two separate apps.

Questions to ask when getting a quote#

To compare quotes from mobile app development companies, get clear answers to these questions:

• Which screens and features are included in the quote, and which are not?
• Are the backend and admin panel part of the quote?
• Will the app be built native or cross-platform? Why was that choice made?
• Whose name will the source code and store accounts be in?
• How will testing work, and for how long after delivery are bug fixes covered?
• How is maintenance after launch priced?
• What will the monthly costs of servers and third-party services be, and who pays them?
• Where will personal data be stored, and how will data protection obligations be met?
• How will things proceed if the scope changes mid-project?

Red flags#

The following signs mean a quote, or a company, deserves a closer look:

• A price given before your needs are heard: Any number quoted before scope is discussed is an estimate that will be corrected later with an extra invoice.
• A single-line quote with no breakdown: If what is included isn't written down, what is excluded becomes a matter of dispute.
• Source code and accounts staying with the vendor: You should own the app and the store accounts; otherwise changing vendors becomes very difficult.
• No mention of maintenance and updates: Launch is not the end of the project; it is the beginning.
• Unrealistic time and price promises: A figure far below the other quotes usually points to a scope that has been misunderstood.
• Vague answers about security and data protection: A team that can't say clearly where the data lives may not have planned how to protect it either.

Conclusion#

What drives mobile app cost is not the technology but the scope: how many platforms, how many features, which integrations and how much maintenance after launch. That is why an accurate quote starts with a well-run discovery.

Frequently Asked Questions#

Why do mobile app prices vary so much between companies?#

Because each company may be pricing the same idea with a different scope. One may include the admin panel, testing and launch support in the quote, while another has priced only the mobile screens. Before comparing quotes, make sure the scope is the same.

Do I need separate apps for iOS and Android?#

Not always. With cross-platform tools such as Flutter or React Native, an app for both platforms can be built from a single codebase. For most business apps that don't need heavy graphics processing or platform-specific hardware features, this approach is enough.

Which costs continue after the app is launched?#

The main ongoing items are the annual Apple developer account fee, server and third-party service costs, bug fixes, security updates and work to stay compatible with new operating system versions. A Google Play account, by contrast, is opened with a one-time registration fee.

What is an MVP, and why is it recommended?#

An MVP is the first version of an app that does its core job. Starting with the most critical features instead of building everything up front keeps the budget under control and lets the next steps be decided by real user feedback.

When can we get an exact price?#

An exact price can be given after the discovery stage, once the scope is clear. When it is known who will use the app, which features are essential in the first version and which systems it needs to integrate with, it becomes possible to prepare an itemised quote.
