App Development Tools Game Developers Should Use When Building An App

As mobile app usage continues to increase and expand, those within the industry continue to create tools and applications that enhance, optimize, and streamline the app development process. As a mobile game developer, you must create fully-functional, beautifully-designed apps that not only serve a purpose but also entertain and engage your users so much that they keep reopening your app again and again.

Whether you’re an experienced mobile gaming developer with full coding knowledge or a beginner Indie developer with little to no development experience, there are plenty of development suites, platforms, design, and marketing tools that support and simplify the mobile game development process. Below are a few of our favorite tools you should have in your arsenal when developing a mobile game app.

App Development Suites & Platforms


unity for app development

Unity3D is arguably the most renowned and popular game engine available to you as a mobile game developer.

Unity allows you to interact with and manipulate your projects’ and apps’ code as well as their visual components, making it the ideal game engine if you’re new to coding or prefer visuals to code. Additionally, Unity allows you to export your projects to every major mobile platform and tons of other programs and tools at no cost.

Unity is free for individual or personal use and costs $75 a month for the Pro license. It is truly an all-in-one software suite for mobile, web, desktop, and console game developers. Known for its ability to create stunning visual 3D gaming experiences across multiple platforms and devices, Unity software was originally meant for OS X in 2005 and has since expanded to target over 20 different platforms. Unity makes it extremely easy to switch from one platform to another directly in the GUI; you simply select the platform of your choice from the menu to switch. Unity as a tool allows you to create beautiful 3D experiences and is extremely compatible with most of the tools and libraries you’ve already got in your toolbox.

Unity provides you with a very user-friendly development environment, making it an excellent game development software for beginners and experienced developers alike. Popular mobile games developed using Unity3D include Assassin’s Creed: Identity (Ubisoft, pictured below) and Temple Run (Imangi Studios).

Unity Asset Store

Unity provides its game and app developers with access to the Unity Asset Store, which is considered one of the best asset marketplaces in the development industry and is a value asset to app developers specifically. Premade artwork, the Multi-Platform toolkit, advanced drawing tools, texture effects, 3D rendering, base models, and extensive libraries of animations, audio, and plugins can all be found in the Unity Asset Store. In addition to the Asset Store, it’s interface is completely customizable with scripts, allowing you to add popular plugins and extensions directly to the User Interface for easy importing and exporting. Lastly, the Asset Store helps developers support each other by allowing you to publish your own packages and tools for other app developers to download.

Unity Community

One of the most valuable features of Unity 3D is the Unity community. Unity offers a community forum and chat channel where you can start or add to discussions with other developers, share your current projects, and view others’ projects. Unity’s issue tracker gives you insight about the status of known bugs and issues. They also provide an ‘Answers’ site with an upvoting system that’s specifically dedicated to helping you get answers from the development community. Lastly, Unity provides a full library of thorough resources that guide you on how to use every single tool available within Unity. Overall, Unity’s extremely supportive community coupled with the Engine’s amazing capabilities make it an integral asset in your developer toolbox.

Unreal Engine

unreal engine

Another popular and powerful mobile gaming tool is Unreal Engine. The Unreal Development Kit, released to the public for free use in 2009, allows mobile game developers to publish and sell games developed using the engine. Unreal code is written in C++ (Unity is C# or Javascript) and was originally intended for first-person shooting games. Unreal Engine 4, the latest Unreal release, still requires developers to pay a 5% royalty fee on profits, but the engine’s lack of membership costs, coupled with its portability and live debugging capabilities, often makes it the top choice for both indie and enterprise developers.

Live Updating and Light Source Programming

Unreal Engine 4 can save you major iteration time due to its live updating capabilities. You can make changes directly to the game’s code while the game is running, and the engine will run in the background to make your changes live. This can reduce the editing process significantly, and can reduce or eliminate designer-to-developer back and forth time.

Another major advantage for Unreal Engine 4 (UE4) is its advanced lighting capabilities. UE4 offers a Cascade Visual Effects editor, which enables you to add advanced detail to fire, smoke, dust, rocky terrains, snow, and more. UE4 allows you to manipulate millions of dynamic particles that can each emit their own light and gives you full control of each particle’s size, color, bounce, density, and other properties. This lets you create incredibly detailed and realistic visuals and scenes.

Unreal Engine Community

The Unreal Engine community rivals the Unity community, with full libraries of assets, documentation, and resources to support you during each stage of game development. Additionally, UE4 has an AnswerHub community that provides answers from other developers and a forum for sharing projects and starting discussions. For mobile developers specifically, Unreal Engine provides “Quick Start” guides to help beginners download the system prerequisites and use templates to begin the development process.

Popular mobile games developed using UE4 include Real Boxing, a realistic and extremely detailed single or multi-player game for Android & iOS, and Joe Montana Football 16, an American football game developed by Superstar Games for iOS & Android devices. Unreal Engine 4 released its teaser trailer for Rivalry to show off its incredible visual and realistic detail capabilities.

App Game Kit

App game kit

While Unity and Unreal create stunningly beautiful 3D and 2D games for consoles, desktop, web, and mobile devices, there are specific mobile-only tools that are solely meant to help you create mobile gaming experiences. In the past, when you wanted to deploy your mobile games on multiple devices, you were forced to repeat the development process for each device’s/platform’s requirements. This costly and repetitive process is (thankfully) eliminated by tools like App Game Kit  that allow for multi-platform deployment. App Game Kit’ allows mobile game developers to code games only once, then deploy it to a variety of platforms and devices. This tool allows you to spend less time reworking existing mobile games and more time developing new games and growing your portfolio.

If you’re just starting out, App Game Kit (AGK) makes it easy for beginners to create and compile everything you need for game development in one place. If you’ve got a bit more expertise under your coding belt, AGK also allows more experienced developers to use C++ libraries for more extensive mobile games.
