A mind map “Weltreise 2027” (world trip) in mind3D with nodes for route, Japan, budget, packing list and a photo mind3D project list on a phone
Why mind3D

More than boxes and lines

Classic mind maps quickly grow too big for one screen. mind3D solves this with levels: every node can hold a whole mind map of its own.

🪐Endless levels

Double-tap and you are inside the node. ▲ takes you back up. Even a huge project stays easy to follow.

🌐Everything in 3D

See your whole mind map as a space of spheres and threads. Rotate, search and jump back to the 2D view with one tap.

🖼More than text

Text, images, sounds and documents such as PDF or Word directly as nodes. Connections can be labelled and coloured.

🔐Yours alone

Everything stays on your device. No account, no cloud, no trackers. Optionally encrypted with AES-256.

Levels

Step into the idea

The node “Japan” from the trip plan holds its own mind map with Tokyo, Kyoto and the cherry blossom. Connections may also cross levels; mind3D shows you where they lead.

  • Double-tap opens a node, ▲ goes up one level
  • A preview shows what is inside a node
  • Labelled connections, e.g. “Shinkansen, 2:15 h”

3D view

Rotate the big picture

One tap on “3D” shows all levels at once as a space. Large spheres are areas with child nodes, the colours come from your mind map. Search flies you straight to the node you are looking for.

Security

Your thoughts stay yours

mind3D works entirely without the internet. If you want more protection, switch on encryption in the Security Center: for all mind maps or just for a vault with its own password.

  • No trackers, no ads, no account
  • AES-256 encryption, key in the phone’s security chip
  • App lock with fingerprint, protection against screenshots
