## What is Structree?

Structree is a simple app for organizing your thoughts into clear structures.

Instead of keeping ideas as scattered notes, Structree helps you break them down into Worlds, Pyramids, Trees, and Nodes. Use it to organize projects, study topics, product ideas, personal plans, or any subject you want to understand more clearly.

Create a World for a broad theme.
Build Pyramids to shape your thinking.
Use Trees to connect related ideas.
Open Nodes to add detailed text and images.

Structree is designed to stay simple. It focuses on structure, not complexity, so you can think clearly without being overwhelmed by too many features.

Key features:
- Organize ideas with Worlds, Pyramids, Trees, and Nodes
- Add text blocks and images to Nodes
- Search and reorder your structures
- Keep your data on your device
- Remove ads with an optional upgrade
- Unlock larger limits with Pro Lifetime

Structree is useful for:
- Structured thinking
- Idea organization
- Study notes
- Project planning
- Product planning
- Brainstorming
- Personal knowledge organization

If normal notes feel too flat, Structree gives your ideas a shape.
