The app is intuitive for beginners. You can quickly drag and drop elements from its extensive library, which includes real products from brands like Unilock and Belgard. For those new to the core principles, brushing up on some foundational concepts can help you get the most out of the tool; this guide on landscape design for beginners offers excellent starting points.
Key Features & Limitations

- Pros: The AR feature is a game-changer for visualizing designs. Its massive, brand-name product library makes finding specific items easy. The interface is user-friendly.

2. Home Outside (Home Outside 3D/Yard Planner)
Home Outside delivers a consumer-friendly mobile app that simplifies 3D and augmented reality landscape planning. As a backyard design app free to start, it provides curated garden collections and realistic 3D plant models tailored to U.S. climate zones. This makes it an excellent choice for American homeowners who want to ensure their plant choices are viable for their location.

The app's strength lies in its beginner-friendly approach to 3D visualization.

This process removes much of the guesswork. For those seeking a deeper understanding of fundamental principles, learning how to design a backyard can help you leverage the app's tools more effectively.
Key Features & Limitations
- Best For: U.S. homeowners (in supported zones) seeking beginner-friendly 3D/AR tools and curated plant collections.
- Pros: The AR walk-through feature provides a powerful sense of space. Its focus on U.S. hardiness zones (5-9) ensures plant selections are practical. The app is free to download for basic planning.
- Cons: The plant library is limited to specific U.S. zones, making it less useful for international users. Accessing the full library requires in-app purchases or a membership.
While the free version is great for initial concepts, users undertaking larger projects may find the paid upgrades necessary.
