About this app

MarginNote is a PDF tool for in-depth reading and study. Keep PDF highlights linked to mind-map cards, then add those cards to review. MarginNote 5 introduces task-based templates for reading, question practice, and vocabulary. MarginNote has evolved since 2013. The upgrade from MarginNote 4 is free. Your study sets, notes, and purchases remain intact.

MARGINNOTE 5: ONE TASK, ONE SETUP

• Templates — a template sets the bottom tools, menus, pens, and excerpt colors. The "Standard" template has four modes: Excerpt, Handwrite, Organize, and Recall. Each mode groups tools for that task.

• Template Gallery — install official templates in one tap. Some templates include examples to help you get started:

– Card Practice: write answers by hand on question cards, check your answers, and focus your next review on questions you haven't mastered yet.…

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Purchases the store lists

 What this app sells

From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
