OSTools is a suite of independent iPhone and iPad tools designed for Old-School Essentials and B/X-style tabletop play. Create characters, organize campaign regions, run encounters, and keep table reference close without losing the feel of pencil-and-paper play.
OSCharacter handles player-side sheets and export. OSReferee imports character data, organizes campaign regions, and gives referees fast access to rolls, encounters, notes, and reference.
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.
