FoldRead

A study and reading app that uses a foldable's two screens to show a textbook page on one side and active-recall questions on the other.

Target user

Medical, law, and language students who own a foldable phone or small tablet

Features
  • PDF or EPUB page on the left, AI-generated comprehension questions on the right that block scrolling until you answer
  • Highlight on one screen creates a flashcard on the other automatically
  • Split annotation: write notes by hand with the S Pen on the inner screen while the source text stays put
  • Study session review that pulls your weakest questions back the next day
Why now

The Z Fold 8 launch with a 4:3 wider screen and 'crease-free' inner display is being marketed directly at readers and multitaskers, and there is no student-facing app that treats the form factor as two simultaneous workspaces.

Feasibility
6/10

Android foldable APIs (Jetpack WindowManager) are mature and a reader+spaced-repetition app is well-understood, but textbook content licensing and a separate tablet/iPad code path are real cost drivers.Galaxy Z Fold 8 release date, price, specs, and must-know features
