How to Code an App From Scratch
The presence of smartphone users globally has skyrocketed, and so has the use of mobile applications. Whether you are an entrepreneur looking to launch a business or a software developer looking to enhance your portfolio, now is the perfect time to create an app.
Today, it is easier than ever to learn how to code an app from scratch. All you need is an innovative idea and a mobile application builder. This article is for everyone interested in app development and app design. Read on for the basics of developing an app for Android and iPhone, different app development tools, and a step-by-step guide to code an app.
Why Creating an App Is a Good Idea
Creating an app in 2021 is a great idea because it is one of the best paths to reaching hundreds of real users in a competitive market. Whether it is a dating app or a game, Android and Apple stores are popular platforms for business success. Several studies on the growing number of smartphone users reflect this sentiment.
According to Statista, it is estimated that there will be around 311.53 million smartphone users by 2025 in the United States alone. This means a mobile application will give you the chance to convert those millions of users into customers.
In addition to the exposure and the fresh stream of conversions, mobile applications are great for capturing user engagement. This is because many apps have an offline mode, are often faster and more convenient, and can use other mobile features such as GPS, camera, and Apple Pay.
Another great factor of mobile applications is the freedom to design. Applications allow functions such as tap, swipe, and hold, unlike a website where a user has to press buttons like back and refresh.
These effective features are significant for user experience and user interface design, also known as UX/UI design. Mobile applications also allow for easier marketing by sending pop-up notifications on the user’s screen rather than sending marketing emails or texts.
Mobile App Development: The Basics
Before jumping into a step-by-step guide for app software development, it is important to know the core concepts of mobile app development. The first thing every application creator needs is a solid app idea that is attractive, unique, and different from its competitors.
To turn your idea into reality, you’ll need to conduct user testing, research industry trends, do competitor and market share analysis, and make a list of functions that your app will offer. Once you have finalized your app idea, you will need to decide whether to build your app for the Android or Apple platform.
This will depend on your target market’s location and the professional developer’s coding skills. Additionally, know that iOS apps use the Swift and Objective-C programming languages, and most Android apps use Java and Kotlin. You must know how to code the correct languages for the platform you’re hoping to use.
How to Code an App for Android
Many app creators use the Java programming language to code for Android apps and Android studio. Java is object-oriented and one of the easiest programming languages for server-side use. Along with Android development, Java’s programming environment is great for enterprise applications, web-based applications, VPNs, and mail servers.
In addition to Java, there are tons of other languages the android app development process uses. You can learn Python, Kotlin, C, C++, and Lua as tools for building different types of apps for Android. Make sure to choose the language depending on your app’s technical specifications and graphic design.
How to Code an App for iPhone
The two most popular languages used to code an app for iPhone are Objective-C and Swift. However, just like Android apps, you can use plenty of other languages for iOS app development. They include Python, Java, HTML5, C#, and C++.
The app design styles and interactions on iPhone and Android differ and are determined by the official guidelines from Google Play and the Apple App Store. Therefore, the platforms use different languages for easier access to the platform’s file systems, hardware, and features.
How to Code an App: A Step-by-Step Guide
There are a multitude of ways to code an app, but the key to an app’s success lies in building a well-optimized and user-friendly mobile application. So, to help you become a mobile app developer, below is a simple step-by-step guide to programming and launching an app. Personalize the steps to meet your app development process.
Step 1: Decide on Your Idea
The first step to coding an app is to come up with an idea that will give your mobile application a great probability for success. To successfully execute this step, you must know the ins and outs of your industry and business. This requires extensive competitor analysis, monitoring industry patterns, and collecting user engagement data.
For those with zero business background, you can enroll in a variety of courses that will provide you with helpful business tips. Make sure your application idea caters to the masses by providing a unique solution and easy access.
Step 2: Brainstorm App Specifications
Once you have a solid idea for your app, it’s time to research and start your technical coding journey. Start by making a list of personalized app specifications. Research the operating platforms and their guidelines, different programming languages best suited for your app, and software tools that will help execute your app vision.
You’d better make an Android app if you want a larger global reach. You can also build an app for both Android and iOS to have a wider pool of users. This will depend on your budget, resources, and time frame. Many people begin with coding an app for one system and adding the second system as the app gains traction.
Step 3: Start Designing
After completing your research, look into your app’s user interface (UI) and user experience (UX) design features. Build a mock-up design of your app based on your soft design. Use this step to find out which tools and languages work best for your application’s advanced features.
Code a prototype of your app that showcases the general outlines of your app. You can use this to pitch your apps to more investors and clients. You should also make sure you design a functional and aesthetically pleasing graphic design interface.
Step 4: Program the App Features
Once you have a prototype and have a programming vision for your app, it’s time to do the backend development. In this step, you’ll polish your app’s features and specifications and get a feel for the overall functionality of the app. In addition, make sure to clearly outline the design, marketing, and business plan elements at this stage.
Step 5: Hire a Team
A capable and successful app doesn’t only rely on the mobile application developer but also on the efforts of several other teams. Start by setting up interviews for the UX designers, UI designers, a marketing team, and a business development expert. Choose the candidates that best suit your budget and required skill levels.
Step 6: Create a Final Version
Once you have established a professional team of experts, it’s time to build your app. After the coding is complete, remember to do ample app testing for software bugs and fix them accordingly. Most apps need many people to build them and make sure every element is running smoothly.
Step 7: Conduct User Testing
Now it’s time to get data on how your target users respond to the app. You can set up multiple user review sessions with a small set of target end users and get actual user feedback. Use the feedback to tweak your application for a better user experience.
Step 8: Sell Your Application
After you feel comfortable with your application’s status, it is now ready to be released. To gain business success, it’s important to market your app. One way to do this is to use different social media platforms to promote your app. With consistent social media publishing and quality content, you can surely promote your app to wider audiences. Market your app on marketplaces including Apple and Google. You can also hire social media influencers to advertise for you.
