Best & Simple App Ideas to Make Money

Part 1. Skill Required For Native App Development

Let’s start with what you need to know to create native apps. In case you’re unfamiliar with the term, these applications are marked by the best performance and UX possible. They’re written in native programming languages and have no limits on the kinds of features or integrations you can implement.

Learn Kotlin, Android SDK & Android Studio

If you aim to create Android apps, Kotlin is the programming language you need to master. (It replaced Java in 2019 because it’s more concise than its predecessor.) It’s designed to be interoperable with Java, so learning Kotlin will be a piece of cake if you already know Java.

Android SDK (software development kit) will be your main toolbox when you write code. So, you need to know your way around its debugger, libraries, documentation, and emulator.

Android Studio is the integrated development environment (IDE) you’ll use most. While you’re mastering it, pay special attention to the layout editor, template-based wizard, and quick fixes.

Learn Swift, iOS SDK & Xcode

Swift is Kotlin’s counterpart for native iOS app development, and their histories are quite similar. Like Kotlin, Swift also replaced Objective-C as the main programming language for iOS devices. The reasoning was the same: Objective-C remained unchanged since the 1980s.

As for the SDK and IDE, you might be in for an unpleasant surprise: you can’t use them on Microsoft Windows computers; they’re available only on macOS. So, if you want to create iOS apps, you must have a Macintosh.

Part 2. Skills Required for Cross Platform App Development

Native apps have their drawbacks: you can’t reuse any of the code of your iOS product to create the same application for Android. That’s why cross-platform technologies are in such high demand. With special tools, you can write the codebase for both apps in one language, cutting the development time and costs in half.

Xamarin (C#)

Backed by Microsoft, Xamarin is a free open-source platform that allows developers to write the codebase with C# and the .NET framework for three target platforms: Windows, Android, and iOS. That codebase gets connected to native components via so-called bridges.

As you probably have already guessed, if you want to use Xamarin in your development, you’ll need to master C# and the .NET framework first. Those are the only two prerequisites, however.

React Native (JavaScript)

Developed by Meta (formerly known as Facebook), this JavaScript framework is made to bring together the best of two worlds. In a nutshell, if you want to create a cross-platform app with React Native, you’ll have to write the code in JavaScript – and it’ll get compiled into either Kotlin or Swift.

To master React Native, you should start with learning the ropes of JavaScript first. Once you have a firm grasp of the JavaScript basics, make sure to get to know React, a JavaScript library that is the basis of React Native.

Part 3. Some More Essential Skills for Any Mobile Developer

Being a mobile app developer isn’t just about writing the code, much like being a blogger isn’t just about writing posts. Apart from coding, you’ll also need to collaborate with other developers, improve the codebase, write documentation, and more. Here are seven skills you’ll need for that.

Using Git Software

This is the standard tool that development teams use to collaborate on any project. So, knowing how to work with repositories, code reviews, pull requests, and merging is a must for you. You can start with GitHub, it’s the most commonly used Git tool out there.

UI & UX Design Basics

The apps you create have to be user-friendly, period. So, even if you spend your days writing code in the IDE, you still have to understand the key principles of usability and user experience to succeed at your job. You should also look into user personas, user interviews, and key metrics.

Cybersecurity Basics

Whenever you write code, you have to assume someone is going to try to find exploits in it and use them. So, you have to be aware of the basics of cybersecurity – and how to apply them when it comes to a particular language, library, or framework.

Writing Clean Code

If you don’t do this, maintaining and updating it is going to be hell for anyone who isn’t you. In a nutshell, writing clean code means naming variables properly, avoiding disinformation, being consistent, keeping your functions small and single-purpose, among other things.

Testing & Debugging

No one can write a perfect piece of software on the first try. What matters is how you pin down the errors in the code and fix them. And to do that, you need to be aware of different types of testing, how to use the right tools, and what to do with bugs.

Writing Documentation

When you’re a beginner in the world of coding, you might not think about commenting at all. But every line of your code has to be documented well for anyone who will work on it in the future. That means leaving comments that explain what purpose every function, variable, or class serves.

Agile Methodology Principles

The majority of development companies build their day-to-day operations on this methodology, so you have to know what it means in practice. In other words, get educated on its core values, iterations and increments, feedback loops, etc.

Apart from all of the technical skills above, recruiters always prioritize candidates that possess the following five soft skills:

  • Communication and interpersonal skills;
  • Collaboration and teamwork;
  • Problem-solving;
