Turn your PDFs and notes into a free mind map on iPhone

Why a free mind map app for iPhone helps with studying
Most people take notes in class or read a chapter on their phone, then struggle to see how the ideas connect. A free mind map app for iPhone can turn that material into a visual outline with one central topic and labeled branches, so the relationships are clear before you memorize anything.
- Start with a single chapter or lecture so the map stays readable on a small screen.
- Keep each branch to a few short sub-points, and split crowded branches into separate maps.
- Test yourself by recalling a branch from memory before opening it.
- Redraw the map blank after a day and check which links you missed.
