Squid Notes (formerly Papyrus) is a tool for taking handwritten notes on Android devices with an active pen, a passive stylus, or a finger. Notes are stored using a vector graphics engine so that they will not pixelate when zoomed and look great "at any zoom level." New notes pages may be blank, ruled, or graphed and can be either infinite in size or constrained to a number of standard paper sizes. Squid Notes can import PDFs or images that can then be annotated (e.g., to grade papers, sign documents, or mark up images). The resulting files can be re-exported as PDFs or images, emailed, shared via Evernote, and more. When a user's device is connected to a projector, Squid Notes can also provide a virtual whiteboard. Squid Notes is available via the Google Play store.
