Developing a custom app is a complex process that involves much more than just writing code. It requires an integrated approach in which many expertises come together, such as technology, creativity and an in-depth understanding of the user experience (UX). In this blog post we will dive into all the steps involved in developing a successful custom app.
Step 1: Idea
Every app starts with an idea. A brainwave, a problem that affects you personally, a daily frustration, market gap? Often your entire idea still fits on a beer mat in this phase (well, that's where the best ideas often arise ;-) and it has not yet been critically reviewed. During this phase it is important to refine your idea and clarify the concept. Some important questions to ask yourself are:
What is the purpose of the app?
Who is the app for?
What problem does the app solve?
Is an app the right thing to solve this problem?
What should the app be able to do at a minimum?
How much will the app cost approximately?
Step 2: Market and competition research
Before you start development, it is very important to do market research. This helps you understand if there is a demand for your app and who your competitors are. You often discover that someone in the world was ahead of you. Bummer! :-( Or... is it? The success of an app depends on many more factors and it is certainly not always the first that is successful. So don't be discouraged if your search in the App stores yields a few hits. Your app can always be better or at least better promoted. Always analyze existing apps that are similar to your idea and identify their strengths and weaknesses.
Step 3: Business model
Developing a high-quality app costs quite a lot of money. Let's be honest about that. So the main question is: “who is going to pay for this?”. For most organizations, an app is an investment that will A. earn money or B. save costs. Therefore, think carefully in advance about the business model for the new app. For example, will you charge subscription fees, charge a fixed purchase amount, will there be advertisements in the app or can users purchase premium components in the app? In this phase it's really about the numbers. Think about things like:
How many users do you expect?
How intensively (and for how long) do they use the app?
What are people willing to pay?
How high are the variable costs?
Finally, there are also organizations with social goals that they want to achieve with the app. Subsidies are often available to cover the costs of these app. Always do a careful calculation in advance to see whether the investment is in proportion to the impact you want to make.
Step 4: functional specifications and wireframing
In this phase you translate your idea into how this should work exactly. This includes describing all the app's functionalities, often in the form of user story maps. You'll also create wireframes, simple sketches of the user interface, to get a visual idea of what the app will look like and how users will navigate.
Step 5: Screen Design
The app's screen design plays an important role in the user experience. UI design (User Interface) and UX design (User Experience) are essential to ensure that the app not only works, but is also user-friendly and attractive. The corporate identity of the app is also designed, including colors, fonts, illustrations, icons and graphic elements.
Step 6: Technology and tools
Choosing the right technology and tools is an important step in the development of a custom app. Questions involved:
What type of app will it be? Apple App store, Google Play store or a web app.
Which languages, frameworks and tools will you use?
The backend infrastructure: where and how will you store data? What data are you going to store? Are there API's with third-party systems?
Step 7: Development
Then it's finally time to actually build the app. In addition to traditional programming, this can also be done with the help of low-code tools such as Flutterflow. These are visual editors that require little custom code to build a full-fledged app. This often makes development faster and the result more reliable. A disadvantage is that you are sometimes dependent on the tooling and that the code is not always 100% optimized. The latter may mean that performance is slightly lower.
Step 8: Testing
Testing is an essential part of the development process. It ensures that the app is free from bugs (errors) and that all functionalities work properly. There are different types of tests, including:
Unit testing: testing individual components or modules.
Integration testing: testing the cooperation between different modules.
User acceptance testing (UAT): testing by end users to ensure that the app meets their expectations.
Performance testing: measuring the speed, responsiveness and stability of the app.
Step 9: Launch
After thorough testing, it's time to launch the app. This includes submitting the app to the relevant app stores (Apple App Store, Google Play Store) or deploying it to a production server. It's also important to have a plan for initial user support and any post-launch bug fixes.
Step 10: Maintenance and Updates
The launch is not the end of the journey. Regular maintenance and updates are required to keep the app running smoothly and to add new functionalities. User feedback is very important here, because it helps to continuously improve the app and keep it relevant.
Step 11: Marketing and User Engagement
A successful app needs a strong marketing strategy to attract and retain users. This includes:
Social media marketing
Content marketing (blogs, videos)
Paid advertisements (such as Google Ads)
Email marketing
Collaborations and partnerships
Conclusion
There is a lot to consider when developing a custom app. It is an extensive and challenging undertaking that requires planning, cooperation, and perseverance. By carefully executing each stage of the process and focusing on the needs of the users, you can create an app that is not only technically superb, but also adds a lot of value for your target group.
