Your PDFs, arranged for the moment you need them.

Put the PDFs you use together into a project, keep the pages you return to one tap away, and move between them without losing your place.

A free beta for iPad, iPhone and Mac is coming soon on TestFlight.

The pages you keep going back to, one tap away.

Save a page to the hotbar and it stays along the edge of the reader, whichever PDF is open. A destination can be a whole page or just the part of it you need, like one table or one stat block.

Give it a short name, and an icon and a color if you want them.

A project, not a pile of files.

A project holds the PDFs you use together: a rulebook and an adventure, a textbook and the week’s readings, a report and the standards it cites.

Switch between them from the drawer. Each one remembers where you were in it.

The PDFs drawer open beside the page, listing the project’s two PDFs, SRD Rules and SRD Monsters.

Groups for the things that come in sets.

Gather related destinations behind one button, such as random tables, conditions or a chapter’s sources. Open the group, tap the page and you’re there.

The Conditions group open above the hotbar, listing eight conditions, each with its PDF and page.

Follow a link, then come back.

Jump to a destination, a search result or a link in the PDF, and Return takes you back to the exact spot you left, at the zoom you left it at. Back and Forward work across every PDF in the project.

Close the app and open it tomorrow, and you’re on the same page.
