OSTools is a suite of independent iPhone, iPad, and Mac tools designed for Old-School Essentials and B/X-style tabletop play. Create characters, organize campaign regions, run encounters, and keep connected table play close without losing the feel of pencil-and-paper play.
OSCharacter handles player-side sheets. OSReferee runs the table on iPhone and iPad. OSTools brings the same referee library and connected session controls to Mac, synchronized privately through Apple CloudKit.
Generate and manage OSE-compatible characters with rules-aware ability scores, combat stats, inventory, encumbrance, retainers, spells, notes, and printable exports.
Prepare and run OSE-compatible campaigns with settlement, hex, faction, religion, NPC, treasure, encounter, combat, dice, and reference tools built for active sessions.
Both apps are designed to work with data on your device first, with user-controlled export, backup, and optional iCloud features where the apps support them.
