# Order of Battle > Order of Battle is a free unofficial Age of Sigmar 4th edition army builder. You put a list together by regiment, add a Regiment of Renown when the army allows it, then keep wounds, spells, and phase abilities in front of you during the game. You don't sign up; the lists live on the device. ## About Order of Battle is a browser hobby helper for Warhammer Age of Sigmar (4th edition). Free fan project: no ads, no subscriptions, no Games Workshop affiliation. Catalogue data comes from the community BSData Age of Sigmar 4th edition project. Points and rules in the app are helpers only. Confirm them with official Games Workshop publications before you play. ## Contact - Website: / - Email: contact@zheat.xyz - Maker site: https://zheat.xyz (this AoS app is free and not for sale; commission or buy list-builder work so the community keeps a helper rather than seeing it closed down) - GitHub: https://github.com/radjivF/orderofbattle ## Product - [Order of Battle](/): Free Age of Sigmar army builder - [Open the builder](/dashboard): Create and play lists in the browser (lists stay on the device; this route is a client app) ## Key information - [FAQ](/faq): Account, privacy, official status, factions, and Play - [How to build an Age of Sigmar army list](/guides/how-to-build-an-age-of-sigmar-army-list): 4th edition list construction - [Free Age of Sigmar army builder](/guides/free-age-of-sigmar-army-builder): What the app does next to other tools - [Tutorials](/tutorials): Step-by-step tutorials for the list builder, Play mode, Math Hammer, and Battle record - [How to use Play mode during an Age of Sigmar game](/guides/play-mode): Open Play from a saved list, track wounds, lasting spells and prayers, and phase abilities - [How to use Math Hammer for Age of Sigmar](/guides/math-hammer): Pick attackers and a defender, add modifiers, and read the results - [How to use Battle record with your Age of Sigmar army list](/guides/battle-record): Add a saved list to Battle record and score turns, primaries, and battle tactics - [Compare Age of Sigmar army builders](/compare): Order of Battle, New Recruit, Listbot, and the official app - [Order of Battle vs Tabletop Tactics and Tabletop Battles](/compare/tabletop-tactics-and-tabletop-battles): Game trackers compared; list, score, and warscrolls in one app - [Age of Sigmar Math Hammer](/guides/age-of-sigmar-math-hammer): Free damage calculator with average kills, damage, chance to wipe, and max damage - [Play](/play): Wounds, weapons, phase abilities, datasheet - [Factions](/factions): Age of Sigmar 4th edition armies you can build - [About](/about): Fan project, data source, and legal status - [What's new](/updates): Bug fixes in this Age of Sigmar army builder release - [Privacy policy](/privacy): Lists stay on the device - [Terms of use](/terms): Unofficial helper; not a Games Workshop product ## Optional - [llms-full.txt](/llms-full.txt): Longer machine-readable summary
