  • Immersive Experiences

Unreal Engine VR

  • VR Gaming
  • AR Marketing
  • Virtual Training
  • 3D Visualization
  • Immersive Experiences

Both are used for vr gaming, ar marketing, virtual training, 3d visualization, immersive experiences, on those jobs the choice comes down to price and fit rather than capability.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ARKit

  • iOS-only platform, not available for Android or other operating systems
  • Location-based AR accuracy limited to 3-5 meters, insufficient for precise applications
  • Cannot handle very fast motion capture
  • Accuracy varies with lighting conditions and surface characteristics
  • Requires iOS 11 or later and specific device hardware

Unreal Engine VR

  • Steep system requirements with demanding GPU and CPU for rendering high-quality VR experiences
  • Only free with 5% royalty after $1 million in revenue, which may impact indie developers at scale

Answered from the vendors’ own pages

ARKit: Is ARKit free to use?

Yes, ARKit is free to use. It is included in Apple's iOS SDK and requires only Xcode and a Mac to start building AR apps. There are no licensing fees or subscription costs.

Unreal Engine VR: Does Unreal Engine support VR and AR development?

Yes. Unreal Engine provides the highest-quality solution for creating augmented reality (AR), virtual reality (VR), and mixed reality (MR) experiences, supporting development for VR, AR, gaming consoles, PCs, and mobile devices.

Source
ARKit: What iOS devices support ARKit?

ARKit is supported on iPhone 6s and later, iPad Pro models, and the latest iPad models. It requires iOS 11 or later. Apple Vision Pro also supports ARKit with enhanced capabilities through visionOS.

Source
Unreal Engine VR: Is Unreal Engine 5 free to use?

Unreal Engine 5 is free for most uses with no upfront cost. If a project earns over $1 million, a 5% royalty applies to future sales.

Source
ARKit: Can ARKit work offline?

ARKit can function offline for tracking and scene understanding since these operations run locally on the device. However, multiplayer AR features and cloud-based object detection require internet connectivity.

Source
Unreal Engine VR: What platforms does Unreal Engine support for VR development?

Unreal Engine supports macOS and Linux development with some limitations, though Windows 10 (64-bit) is the primary development platform. It supports VR development targeting various VR headsets.

Source
ARKit: Does ARKit integrate with game engines?

Yes, ARKit integrates with Unity through the Unity ARKit Plugin and with Unreal Engine. Developers can also use it with Metal, SceneKit, and Apple's RealityKit framework.

Source
ARKit: What are ARKit's limitations with location-based AR?

ARKit's location-based positioning has accuracy limitations. Image-based positioning is primarily useful in urban areas, and beacon-based navigation provides accuracy of 3-5 meters, which is insufficient for precise AR applications requiring 1-meter accuracy or better.
