Branch Map: Offline Mind Maps

Branch Map is a lightweight offline mind-mapping app with no sign-up, no cloud, and no login. When an idea hits, open the app, start a new map, and tap out branches — that's it.

Key features
- Custom canvas: a hand-drawn-style mind map with a central node and curved branches radiating outward
- Tap a node to add a child node; double-tap to edit text inline
- Drag a node and its whole sub-branch moves with it; long-press for delete, color, and collapse options
- Two-finger pinch-zoom (0.3x-2.5x) and one-finger pan to explore freely; double-tap empty space to fit the whole map on screen
- Collapse and expand branches to keep large maps manageable
- One-tap "Tidy Up" for automatic radial re-layout
- 8 branch colors to visually separate topics
- Undo/redo up to the last 30 steps
- Export finished maps as PNG images to save to your gallery or share
- Everything is saved automatically on-device (Room database) — fully offline, no account, nothing sent to any server
- Korean/English support, dark mode support

Great for
- Students and planners brainstorming ideas
- Anyone outlining a presentation or piece of writing visually
- Organizing everyday plans like trips or moves

No heavy account sign-up, no subscription cloud sync — just branch out your thoughts exactly as they come.
