Thinking about developing an app for your business? Then you need to understand more than just “how much does an app cost?”. A successful app requires the right strategy, the right technology choices, clear prioritization of features, and a realistic plan for launch, operations, and continued development.

In this guide, we explain how app development works from idea to finished product, what affects the price, how long different types of apps take to build, and when you should choose native, React Native, or another technical solution. The guide is written for decision-makers, founders, project managers, and business owners who want to make a more confident decision before investing in an app.

What is app development?

App development is the process of planning, designing, building, testing, launching, and continuously improving a mobile application for iOS, Android, or both platforms. For businesses, app development is rarely just about the app itself. It often needs to connect with business systems, payment solutions, BankID, APIs, customer data, inventory, booking systems, or other internal processes.

A modern app can be built in several ways. Some apps are developed natively in Swift for iOS and Kotlin for Android. Others are built using cross-platform technologies such as React Native or Flutter, where much of the code can be reused across iOS and Android. The best option depends on the app’s goals, budget, integration needs, performance requirements, and how quickly you need to get to market.

When is an app the right solution?

An app is often the right solution when users need to do something frequently, quickly, or in a mobile context. This might include customers booking services, field staff working on site, drivers reporting deliveries, or warehouse employees scanning products. In cases like these, an app can create a much better experience than a standard website.

However, an app is not always the first step. If users only need to read information, fill in a simple form, or visit the service once or twice, a responsive website or web app may be a better and more cost-effective option. A serious app developer should therefore not start by trying to sell an app, but by understanding the problem that needs to be solved.

What does app development cost?

The cost of app development varies greatly depending on scope, design level, technology choices, integrations, and how much needs to be built from scratch. A simpler app can sometimes be developed for a few hundred thousand kronor, while a more advanced business-critical app with a backend, admin interface, integrations, and ongoing development often requires a larger investment.

The most important thing is not to start with a long list of requirements, but to define which first version actually needs to be launched. In many projects, an MVP — Minimum Viable Product — is the smartest first step. This means building the smallest version that can create real value, be tested by real users, and provide a basis for the next decision.

Frequently asked questions about app development

How much does it cost to develop an app?

A simpler app can often start from around SEK 100,000–250,000, while a more advanced business app with a backend, admin panel, and integrations often starts from around SEK 500,000 and upwards. The price is mainly affected by features, design, technology choices, integrations, security requirements, and how much needs to be built from scratch.

How long does app development take?

A simpler first version can sometimes be developed in 6–10 weeks. A more advanced app often takes 3–6 months or longer. In addition to the development itself, time is needed for strategy, UX, design, testing, launch, and approval in the App Store and Google Play.

Should you build an app for iOS, Android, or both?

It depends on the target audience. If most users are on one platform, it may be wise to start there. For many companies, however, it is best to launch on both iOS and Android, especially if the app will be used by customers or employees with different types of phones.

What is the difference between a native app and React Native?

A native app is built separately for iOS and Android, usually in Swift and Kotlin respectively. React Native makes it possible to build apps for both platforms with a largely shared codebase. Native is best suited when maximum performance or deep platform integration is required, while React Native is often effective for business apps, MVPs, and apps with many common business functions.

Does the app need a backend?

Most business apps need some form of backend. The backend handles things such as user accounts, data storage, permissions, integrations, payments, an admin panel, and communication between the app and other systems. An app without a backend is mainly suitable for simpler informational apps.

What is an MVP in app development?

An MVP, Minimum Viable Product, is the first version of the app that contains enough features to create value and be tested by real users. The purpose is to launch faster, reduce risk, and make better decisions based on real feedback.

Can you continue developing the app after launch?

Yes. An app should almost always be seen as a long-term product, not a one-off project. After launch, you can improve the user experience, add features, optimize performance, track user data, and adapt the app to new business needs.

How do you publish an app in the App Store and Google Play?

To publish an app, you need developer accounts with Apple and Google, app metadata, screenshots, descriptions, a privacy policy, and often test versions. The app is reviewed before it is published. The review may require adjustments, especially if the app handles login, payments, or personal data.

Can an app be connected to our business system?

Yes, if the business system has an API or another integration option. Many business apps are connected to CRM, ERP, accounting systems, inventory systems, booking systems, or internal databases. Integrations are often one of the most important parts of an app project.

Is app development the right choice, or is a web app enough?

If users need push notifications, camera access, GPS, offline mode, scanning, or a fast mobile experience, an app may be the right choice. If the need is mainly information, simpler forms, or occasional use, a responsive website or web app may be more cost-effective.

Who owns the code after the project?

This should be regulated in the agreement with the app developer. As a customer, you should ensure that you have clear rights to the code, documentation, and the accounts required to continue operating the app.

How do you get started with app development?

Start by defining the problem, the target audience, and the value the app should create. After that, the next step is often a workshop or feasibility study where features, technology choices, budget, and timeline are clarified before design and development begin.
