Every Rule. Right There.
The Complete Pathfinder & Starfinder Reference
Lodestone puts the full Pathfinder and Starfinder rulesets at your fingertips — instantly searchable, deeply cross-linked, and fully offline. No more flipping through books mid-combat. No WiFi required.
Built for the Table
The Pathfinder ruleset spans dozens of books and thousands of entries. Finding a feat's prerequisite chain or a monster's full stat block mid-session shouldn't take thirty seconds of frantic page-flipping. Lodestone makes it three.
Instant search. Deep cross-links. Everything offline.
Built to Keep Up With Your Session
Instant Full-Text Search
Search across every spell, feat, class, monster, and item in the ruleset simultaneously. Results appear in under 200ms, grouped by type so you find what you need without hunting. The whole rulebook, searchable in a tap.
Deep Cross-Linking
Every rule reference is a live link. A feat that requires a specific spell links directly to it. A monster's special ability links to the feat it mirrors. Follow the rules wherever they lead — no backtracking, no context lost. The rules as they were meant to be read.
Columnar Hierarchy Navigation
Browse from book to chapter to entry in a fluid columnar layout — especially powerful on iPad. Your navigation context stays visible as you drill down, so you always know where you are and how you got there. Structure that mirrors the rules themselves.
Offline-First
All content lives on your device. No server dependency, no WiFi required, no loading spinners at the table. The Core Rulebook ships with the app — premium content downloads once and stays put. Works wherever you play.
Favorites & Bookmarks
Bookmark any entry and organize it into folders. Build a quick-reference list of your character's spells, your GM prep monsters, or any combination of rules you reach for constantly. Your most-used rules, always one tap away.
iPad & iPhone, Both First-Class
On iPad, the columnar layout keeps your place while you read. On iPhone, a clean navigation stack gives you the same depth in your pocket. Dark mode, Dynamic Type, and VoiceOver supported throughout. Native. Fast. No compromises.

Coming Soon
Pathfinder 2E rebuilt the game from the ground up — a streamlined action economy, sweeping character customization through ancestry and class feats, and a massive bestiary. Lodestone: PF2 brings the same instant-search, cross-linked reference experience to the current edition.
Coming Soon
Starfinder takes the Pathfinder foundation into a science-fantasy future — starships, alien worlds, mechs, and blasters alongside swords and spells. Lodestone: SF1 covers the full ruleset: classes, races, equipment (including tech and hybrid items), spells, and the alien archive.
Stop Searching. Start Playing.
Lodestone: PF1 is free to download with the full Core Rulebook included. Premium unlocks the complete expanded ruleset for $2.99/month — and covers PF2 and SF1 when they launch.

Questions?
What's free vs. premium?
The Core Rulebook — core classes, races, feats, spells, and base rules — is free forever. Premium ($2.99/month) unlocks the full expanded ruleset: all supplements, prestige classes, the complete bestiary, magic items, and advanced systems.
Does the premium subscription cover all three apps?
Yes. One subscription unlocks premium content across Lodestone: PF1, PF2, and SF1 simultaneously.
Does it work offline?
Yes. All content is stored on your device after the initial download. No WiFi, no servers, no loading at the table.
When are PF2 and SF1 coming?
Both are in development. PF2 is next, followed by SF1. The same UI, search, and navigation you know from PF1 carries over to both.
Is my data private?
