About OSTools

OSTools is a suite of independent iPhone and iPad tools designed for old-school tabletop play.

Tools for both sides of the table

OSCharacter supports guided character creation, live character records, and export. OSReferee organizes campaign regions and helps referees prepare and run encounters. Both are designed for Old-School Essentials and B/X-style play.

Local-first by design

The apps keep character and campaign data on the device first. Export, import, backup, and optional iCloud features are available where each app supports them, so players and referees can choose how their table data moves.

Independent compatibility

OSTools apps are independent third-party tools. They are not affiliated with, endorsed by, sponsored by, or approved by Necrotic Gnome. Old-School Essentials is a trademark of Necrotic Gnome.
