Augmented reality (AR) is a technology that overlays digital content, such as images, videos, sounds, or texts, onto the real world through a device’s camera, screen, or headset. AR apps can enhance the user’s perception of reality by adding information, entertainment, or interaction to their surroundings. Some of the most popular AR apps include Pokemon Go, Snapchat, and IKEA Place, which allow users to catch virtual creatures, apply funny filters, and visualize furniture in their homes, respectively.Â
AR has many benefits for both users and businesses. For users, AR can provide a more immersive and engaging user experience, as well as offer new ways of learning, exploring, and communicating. For businesses, AR can increase customer loyalty, retention, and revenue, as well as improve brand awareness, marketing, and customer service. According to a report by Statista, the global revenue of the AR market is expected to reach $198 billion by 2025, up from $10.7 billion in 2019.
However, developing AR apps for mobile devices is not an easy task. It requires overcoming various challenges and seizing various opportunities in order to create high-quality and successful AR apps. In this blog, we will discuss some of the main aspects of developing AR apps for mobile devices, such as choosing the right platform and tools, designing for user interaction and immersion, and testing and optimizing for performance and compatibility
Choosing the right platform and tools
One of the first steps in developing an AR app for mobile devices is choosing the right platform and tools that suit your app’s goals, target audience, and budget. There are many AR platforms and tools available in the market, each with its own features and limitations. Some of the most popular ones are:
ARKit:
This is Apple’s framework for developing AR apps for iOS devices. It supports features such as face tracking, object detection and recognition, plane estimation and alignment, image tracking and registration, environment mapping and lighting estimation, etc. It also integrates with other frameworks such as SceneKit, SpriteKit, Metal, etc.
ARCore:
This is Google’s platform for developing AR apps for Android devices. It supports features such as motion tracking, environmental understanding, light estimation, cloud anchors, depth API, etc. It also integrates with other platforms such as Unity, Unreal Engine 4, etc.
Unity:
This is a cross-platform game engine that can be used to develop AR apps for both iOS and Android devices. It supports features such as 3D graphics rendering, physics simulation, animation system, scripting language (C#), asset management system, etc. It also integrates with other platforms such as ARKit, ARCore, Vuforia, etc.
Vuforia:
This is a platform that specializes in image recognition and tracking for AR apps. It supports features such as image targets, model targets, multi-targets, cylinder targets, user-defined targets, object recognition, etc. It also integrates with other platforms such as Unity, Unreal Engine 4, etc.
To choose the best option for your app, you need to consider several factors, such as:
- The type of AR experience you want to create: Do you want to create a marker-based or markerless AR app? Do you want to use 2D or 3D content? Do you want to use realistic or stylized graphics? Do you want to use location-based or indoor-based AR?
- The target devices you want to support: Do you want to support only iOS or Android devices? Or do you want to support both? Do you want to support specific models or versions of devices? Do you want to support different screen sizes and resolutions?
- The development time and cost you have: Do you have enough time and budget to develop your app? Do you have enough skills and resources to use the platform or tool? Do you need any additional licenses or fees to use the platform or tool?
Some tips and best practices for choosing the right platform and tools are:
- Research the features and limitations of each platform or tool before deciding which one to use.
- Compare the pros and cons of each platform or tool based on your app’s requirements.
- Choose a platform or tool that has good documentation, support, and community.
- Choose a platform or tool that is compatible with your existing development environment and workflow.
- Choose a platform or tool that allows you to test and debug your app easily and effectively.
Designing for user interaction and immersion
Another important aspect of developing an AR app for mobile devices is designing for user interaction and immersion. User interaction refers to how users interact with your app and its content, such as tapping, swiping, pinching, rotating, etc. User immersion refers to how users feel immersed and engaged in your app and its content, such as feeling presence, emotion, curiosity, etc.
To create engaging and immersive AR experiences that intelligently interact with the real world, you need to consider several factors, such as:
User interface design: This refers to how you design the visual elements of your app, such as buttons, menus, icons, text, etc. You need to make sure that your user interface is clear, simple, and intuitive, and that it does not obstruct or distract from the AR content. You also need to make sure that your user interface is consistent and coherent with your app’s theme and style.
User feedback: This refers to how you provide feedback to users about their actions and the app’s status, such as sounds, vibrations, animations, etc. You need to make sure that your user feedback is timely, relevant, and informative, and that it enhances the user’s sense of control and satisfaction. You also need to make sure that your user feedback is appropriate and respectful to the user’s context and preferences.
Sound effects: This refers to how you use sound effects to complement your AR content, such as ambient sounds, voice-overs, music, etc. You need to make sure that your sound effects are realistic, synchronized, and spatialized, and that they create a sense of immersion and atmosphere. You also need to make sure that your sound effects are not too loud or annoying to the user or others around them.
Lighting, shadows, occlusion, etc.: These refer to how you use visual effects to make your AR content look more realistic and integrated with the real world, such as adjusting the brightness, contrast, and color of your AR content according to the real-world lighting, adding shadows and reflections to your AR content according to the real-world objects, hiding or showing your AR content according to the real-world occlusion, etc. You need to make sure that these visual effects are accurate, consistent, and smooth, and that they create a sense of depth and realism. You also need to make sure that these visual effects are not too computationally intensive or battery draining for your device.
Some examples of well-designed AR apps that use these elements successfully are:
This is an AR game that allows users to catch and collect virtual creatures called Pokemon in the real world. It uses user interface design, user feedback, sound effects, and visual effects to create an engaging and immersive AR experience. For example, it uses a simple and intuitive user interface that shows the user’s location, nearby Pokemon, items, etc. It uses sounds, vibrations, and animations to provide feedback on the user’s actions and the game’s status. It uses ambient sounds, voice-overs, and music to create a sense of atmosphere and emotion. It uses lighting, shadows, occlusion, etc. to make the Pokemon look more realistic and integrated with the real world.

You also need to make sure that your app adapts to different screen sizes, resolutions, and orientations, and that it does not distort or cut off any content.
- Environment conditions: This refers to the physical conditions of different environments that you want to support, such as lighting, noise, clutter, motion, etc. You need to make sure that your app works well in different lighting conditions, such as bright, dim, or changing light. You also need to make sure that your app works well in different noise levels, such as quiet, loud, or varying noise. You also need to make sure that your app works well in different clutter levels, such as clean, messy, or dynamic clutter. You also need to make sure that your app works well in different motion levels, such as still, moving, or shaking motion.
- User scenarios: This refers to the use cases and situations of different users that you want to support, such as age, gender, location, preference, etc. You need to make sure that your app is suitable and accessible for different age groups, such as children, adults, or seniors. You also need to make sure that your app is appropriate and respectful for different genders, cultures, and languages. You also need to make sure that your app is relevant and useful for different locations, such as urban, rural, or remote areas. You also need to make sure that your app is customizable and adaptable for different preferences and needs.
