What is Penink Pro?

Penink (free) includes handwriting, Explorer-style folders, notebooks, PDFs, tabs, split view, and search on iPad and Android tablets.

Penink Pro is an in-app upgrade for optional smart tools and extra study workflows: summarize, explain, flashcards, study questions, and related-note help.

You can organize and write without Pro. Purchase and restore are handled by the App Store or Google Play on your tablet. See Pricing for a plain-language comparison.
