How to Develop an App: A Complete Step-by-Step Guide (2026)

To develop an app, start by validating the idea, defining functional requirements, choosing the right platform (iOS, Android, or web), designing UX, building the application using code or low-code, testing features, deploying to production, and continuously improving based on user feedback. This guide explains the entire app development process step-by-step, plus how low-code platforms like Kissflow help enterprises build applications 10x faster.

What Is App Development?

App development is the process of designing, creating, testing, and deploying a software application. Whether you want to develop an app for mobile, web, or enterprise workflows, the goal is to solve a clear user problem with a functional digital product.

Users often search using variations like “how to build an app,” “how to create an application,” or “how to make an app,” but the intent is the same—learn how to build an application from start to finish.

1. Come up with an idea

Before you begin, clarify how to build software applications that align with your business goals. Define what the app should do, who it serves, and how it adds long-term value.

2. Know your audience

Define who your target audience will be. Create personas so you can better understand who your app’s target users are and what platforms they’re using. Consider what type of app your audience will want to use time and again.

3. Do your research

Conducting market research is essential because with the millions of apps available today, how will your app stand out from the crowd? Knowing what your competitors are already doing can give you an edge and can help you know what you’re potentially going up against.

Start by doing research in your industry or market to find out what apps are already available within your niche. This can also help you determine what features or functionalities can help set your app apart. You can also consider doing interviews or getting feedback from potential users to have an idea of what they need or what their pain points are.

4. Create a concept proof

Concept proofing helps you find out if your app can potentially be a solution to an existing problem. Outline your priorities for the app and sit the team down, making sure that everyone is on the same page concerning your goals.

5. Determine the features you want your app to have

Create a list of possible features you want in your app. Note that these features may change depending on the actual development process and the feedback you get from your testing phase.

6. Create mockups and consider the graphic design aspect

Once you have your list of features, you can start creating mockups of what your app could potentially look like. You can start with a rough sketch before creating an actual mockup. When building a mockup, you must consider how your users will see and interact with your app.

Don’t forget to come up with an eye-catching graphic design for your app. When designing, you may want to work with a graphic designer who has experience with UI/UX.

7. Build a marketing plan

Your marketing plan is an important part of app development. How else will you put your app out there and get users to not only notice it but also download and use it? Ideally, you want to create a marketing plan even before you launch your app. Generate buzz for it by creating a website, sharing your app development journey on your social media channels, or using a pre-launch email list for your visitors or patrons.

8. Develop your app

Once you’ve nailed the basics down, you can start coding. But before you start writing code, you may want to consider several critical components such as the front and back-end development. You will also need to create a test environment for execution.

9. Do repeated testing and get feedback

Repeated testing is crucial if you want your app to be successful. During the testing phase, you’ll have to check for its front-end and back-end functionality, its compatibility with different devices, potential issues with integration, as well as installation and storage matters, such as the size of your app or if will it download correctly to the intended device.

After testing, you’ll need to have test users use your app so you can get user feedback and find out what else your potential customers may need. And getting feedback doesn’t have to stop at the testing phase. You can continue gathering feedback from users even if the app goes live.

10. Launch your app

The final step is the actual launching of your app on your preferred app store. You’ll need to follow your preferred app store’s regulations and requirements before you can successfully launch your app. While you can publish your app on both the Play Store and the Apple App Store, you may also want to focus on publishing on a single platform.

Types of applications you can develop

There are plenty of apps available today, such as music apps, database software, team collaboration apps, and multimedia software. While you can explore how to build software applications across these categories, there are three types of application development that you need to prioritize: team apps, departmental apps, and enterprise apps.

Web apps

Web application development uses browsers to perform a function. It facilitates enhanced communication between you and your customers, and they can be customized according to your business’s needs. For example, a web app can help you collect information or complete transactions with your customers. Unlike other app types, creating a web app doesn’t require much maintenance and is accessible anytime, anywhere using a web browser.

Furthermore, custom web applications can be accessed using different platforms, whether your customers are using a desktop or a mobile device. Some common web apps include Google Docs, cloud storage, file conversion programs, and email programs.

Business apps

Creating business apps such as communication apps, time-tracking software, or customer relationship management apps, helps streamline a company’s operations, whether it’s a large enterprise or an SMB. This type of app allows businesses to better manage their teams, finances, schedules, and business data.

Desktop apps

Desktop apps are applications that require a desktop computer to run. These are typically developed to run on specific operating systems, such as Windows or Mac, and any updates should be manually installed by the user. Unlike the other two apps, desktop apps function in an isolated environment, which can give users better security.

3 steps to consider before developing an application

Choosing the right tools can make a big difference when building an app. Best application development tools help streamline the process, improve collaboration, and bring ideas to life faster. Before you set out to build your app, there are three key things you should consider before developing an app:

Your business goals

This might seem surprising, but before building an app, you may want to ask yourself if you need one in the first place. Reassess your business goals. How will developing an app help you reach your goals? What role will it play in your long-term vision for your enterprise?

Your users

Who are you building an app for? Knowing who your target audience is will play a major role in app development, including what features you’ll need to put into it. There’s no point in building an app that has a limited scope.

The app development process

Application development can use up a lot of resources. Even if you have the right team or the skills needed to build the perfect app, you must also consider the testing and debugging aspects as part of the process. Therefore, you will still need to allot time for these steps prior to launch.

Two approaches to app development

When you develop an app, there are two approaches you can follow:

• Traditional
• Modern

Traditional app development

In the traditional approach, such as the waterfall model, only professional developers are involved in the application development process, given that this requires manual programming and writing lines of code from scratch.

Every successful app begins with careful planning. App development planning focuses on setting clear objectives, identifying key features, and outlining the steps needed to turn an idea into a working application.

It also tends to follow a downward flow, from initial planning to the release, which can be expensive and time-consuming. However, it does give developers more control over how they write their code.

Modern app development

With the modern approach, such as the agile methodology, you’re using cloud-native architectures along with other microservices that facilitate faster time to market. It also provides a more flexible way to develop an app, allowing you to recalibrate your application according to your customers’ different needs. The modern approach also allows companies and developers to optimize app development costs and develop an app remotely.

The low-code approach is part of the modern way of developing an app. Here, developers or even business users leverage a low-code platforms like Kissflow with pre-built templates and a visual drag-and-drop editor for application development.

For most business applications, the fastest path from idea to deployment is a no-code app builder like Kissflow — it handles the infrastructure while you focus on the logic and user experience.

How application development can be a game changer

Low-code platforms make building apps for businesses more democratic. With apps quickly becoming a central part of people’s lives, understanding how to make an application using alternatives to traditional methods can jumpstart your journey to developing the best app for your needs.

Furthermore, with application development, you don’t need to be a professional developer. You can use app development platform like Kissflow to speed up the process, all while having the flexibility of designing an app that will cater to your audience’s changing needs. Best no code tools for app development make it possible to create apps without writing code, using drag-and-drop features and pre-built templates that speed up the development process.

FAQ's - How To Develop an Application

What is the step-by-step process for developing a business application?

Start with discovery—understand the problem, the users, and the business goal before selecting any tools. Write clear requirements covering what the app must do, who uses it, and what integrations it needs. Design the user interface and data architecture. Move into development using your chosen approach—traditional coding, low-code, or a hybrid. Test thoroughly at every stage, not just at the end. Deploy to production through a controlled rollout, then monitor continuously and iterate based on real usage data.

How do you choose the right development approach for a business application?

It depends on complexity, timeline, team skills, and budget. If the app involves standard business logic—forms, workflows, approvals, reporting—a low-code platform is almost always faster and more cost-effective. If the app requires highly specialized algorithms, unique hardware integrations, or performance at extreme scale, traditional development gives more control. Many enterprises use a hybrid approach: low-code for the majority of applications, custom code only where it's genuinely necessary.

What role do end users play in the application development process?

End users are critical—not optional. They understand the actual workflows better than any developer or project manager. Involving them in requirements gathering prevents building something that looks good on paper but fails in practice. Regular user testing sessions during development surface usability issues before they become expensive to fix post-launch. After launch, user feedback should directly drive the product roadmap. Applications built without meaningful user input almost always require costly rework.

What are the most common reasons application development projects fail?

Unclear requirements are the number one culprit—teams build what they think is needed rather than what's actually needed. Scope creep without corresponding timeline and budget adjustments is a close second. Poor communication between IT and business stakeholders, insufficient testing before launch, and underestimating the technical debt being accumulated all contribute significantly. Projects without a dedicated product owner who makes decisions and keeps work moving tend to drag, lose momentum, and miss deadlines.

How do you manage changes during the application development process?

Change is inevitable, so plan for it explicitly. Use a formal change request process that evaluates the impact of every proposed change on scope, timeline, and cost before accepting it. If you're using Agile, changes can be added to the backlog and prioritized for future sprints rather than disrupting the current one. The goal is not to block change entirely—it's to ensure that changes are conscious decisions made with full awareness of their trade-offs and downstream consequences.
