If you’re looking for a custom golf simulator design app specifically for mobile devices, there aren’t as many options available compared to desktop software. However, here are a few mobile apps that can assist you in designing a custom golf simulator experience:

Golf Simulator Designer (iOS): Golf Simulator Designer is an iOS app that allows you to create and customize your own virtual golf courses. It provides tools for terrain shaping, adding objects and hazards, and adjusting hole parameters. You can also simulate ball flight and gameplay to test your course designs.

WGT Golf Course Builder (iOS, Android): WGT Golf Course Builder is a mobile app available for both iOS and Android devices. While it’s primarily designed for creating custom courses in the World Golf Tour game, you can also use it to design courses for personal use in your golf simulator. The app offers various customization options and an intuitive interface for designing holes and placing elements.

Perfect Parallel Golf Simulator (iOS): Perfect Parallel Golf Simulator is an iOS app that combines both course creation and gameplay features. It allows you to design and build your own golf courses, adjusting terrain, planting vegetation, and placing objects. You can then play your custom courses within the app using the golf simulation engine.

It’s important to note that these mobile apps may not have the same level of functionality and precision as desktop software or dedicated golf simulator systems. However, they can still provide a fun and interactive way to experiment with course design and layout using your mobile device.

Before using any of these apps, make sure to check their compatibility with your specific device and operating system. Additionally, keep in mind that these apps may have different features, ease of use, and limitations, so it’s advisable to explore each app further to determine which one best fits your needs and preferences.
