How to Make an App – The Ultimate Guide

The Ultimate Guide to Building Your Own App from Scratch, Step-by-Step

Welcome, Asensio, to the ultimate guide on how to make an app! In today’s digital age, app development has become more accessible, and many beginners and entrepreneurs have found success in creating their own apps. With this guide, we hope to walk you through the process of making your own app, starting from scratch. Whether you’re an experienced developer or just starting with coding languages, this guide will cater to your needs.


Before we dive into the intricacies of app development, let’s start with the basics. An app, short for “application,” is a software program designed to perform specific tasks on a mobile or desktop device. Apps can serve various functions, from entertainment to productivity to communication, and can be built for different platforms, including iOS, Android, and web-based apps.

In today’s digital age, apps have become an integral part of our lives. According to Statista, global mobile app revenues are expected to reach $935 billion by 2023, which shows the enormous potential of app development in today’s market. With the right idea and execution, your app can be the next big thing!

So, let’s get started on building your own app!

Step 1: Define Your App Idea

Before you start coding your app, you need to have a clear idea of what you want to build. Your app idea should cater to a specific target audience and solve a particular problem. To get started, ask yourself these questions:

1. What problem does my app solve?
2. Who is my target audience?
3. What features do I want to include in my app?
4. What is my budget for building the app?

Once you have identified your app’s purpose, audience, and features, you can move on to the next step.

Step 2: Choose the Platform

Now that you have a clear idea of what you want to build, it’s time to choose the platform for your app. There are three main platforms to consider: iOS, Android, and web-based apps.


iOS is a mobile operating system created by Apple and is used exclusively on Apple’s devices. This platform has a significant market share in the United States, Europe, and Japan. If your app caters to users in these regions or targets Apple users, then iOS should be your first choice.


Android is a mobile operating system owned by Google and is used on several mobile devices worldwide. This platform has a vast market share globally and is popular among users who prefer open-source technology. If your app caters to a broad audience or targets Android users, then Android should be your choice.

Web-Based Apps

Web-based apps are those that run on web browsers and do not require installation on the device. These apps are platform-independent and can run on any device with a web browser. If your app requires a web-based interface or targets users who prefer browser-based apps, then a web-based app should be your preference.

Step 3: Choose the Right Programming Language

Now that you have decided on the platform for your app, it’s time to choose the right programming language. Each platform has its programming languages, and you need to select the one that best fits your app idea and target audience.

iOS Programming Languages

The primary programming languages for developing iOS apps are Swift and Objective-C. Swift is a modern and user-friendly language suitable for beginners, while Objective-C is a more traditional language that has been used for iOS app development for several years.

Android Programming Languages

The primary programming language for Android app development is Java, and Kotlin is also gaining popularity among Android developers. Java is a versatile and widely-used language, and Kotlin is a modern and user-friendly language suitable for beginners.

Web-Based App Programming Languages

The primary programming languages for web-based app development are HTML, CSS, and JavaScript. HTML is used to structure the web page, CSS is used to style the web page, and JavaScript is used to create interactive elements on the page.

Step 4: Design Your App

Designing your app is a crucial step in the app development process. Your app’s design will determine the user experience and engagement, and a poorly designed app can lead to poor app ratings and user reviews. When designing your app, keep these tips in mind:

1. Keep the design simple and intuitive
2. Focus on the user experience
3. Use a consistent color scheme and font
4. Include only essential features to avoid clutter

Step 5: Develop Your App

Now that you have defined your app idea, chosen the platform and programming language, and designed your app, it’s time to start coding your app. This step is the most challenging and time-consuming, and you must be patient and focused during this process.

You can choose to develop your app using an Integrated Development Environment (IDE) like Xcode for iOS apps, Android Studio for Android apps, and Visual Studio Code for web-based apps. These IDEs provide a user-friendly interface and tools to help you develop your app efficiently.

Step 6: Test Your App

Testing your app is critical to ensure that it runs smoothly and without bugs. You can test your app on a simulator or emulator if you are developing for iOS or Android platforms or on various browsers if you are developing a web-based app.

You should test your app for compatibility with different devices, screen sizes, and operating system versions. This step will help you identify and fix any issues before launching your app.

Step 7: Launch Your App

Once you have finished developing and testing your app, it’s time to launch it. To launch your app, you need to create an account with the respective app store or platform, such as the Apple App Store, Google Play Store, or web-based app stores.

You should also create a marketing plan to promote your app and reach your target audience. You can use social media, email marketing, and paid advertising to promote your app and increase its visibility.


1. How long does it take to make an app?

The time it takes to make an app depends on various factors, such as the complexity of the app, platform, and programming language used. On average, it can take anywhere from a few weeks to several months to develop an app.

2. How much does it cost to make an app?

The cost of making an app varies depending on the platform, programming language, and complexity of the app. On average, it can cost anywhere from $10,000 to $100,000 to develop an app.

3. Do I need to know coding to make an app?

While coding knowledge is not necessary, it can be helpful in app development. However, you can use various app-building tools and platforms that do not require coding knowledge.

4. How do I monetize my app?

You can monetize your app by using various methods, such as in-app purchases, advertisements, or charging for the app download.

5. How do I protect my app idea?

You can protect your app idea by obtaining a patent or trademark or signing a nondisclosure agreement (NDA) with developers and stakeholders.

6. How can I improve my app’s visibility?

You can improve your app’s visibility by using various marketing strategies, such as social media, email marketing, and paid advertising. You can also optimize your app for app store search and use app store optimization (ASO) services.

7. How do I update my app?

You can update your app by releasing a new version with bug fixes, feature upgrades, and security patches. You should also notify your users of the app update.


In conclusion, making an app can seem daunting, but with the right idea, execution, and tools, anyone can do it. We hope this ultimate guide has given you the knowledge and confidence to start building your app today.
