LegionCompanion

• •Weapons, unit links and special-rule summaries are available as the reference page loads, before JavaScript starts. Search, filters, calculators and rule popups keep their existing behaviour. Returning from a datasheet keeps the catalogue's own saved scroll position.

• •Cloud sync protects pending edits, retries failed deletions and shows Synced only when the current content is confirmed. Moving device data into an account requires an explicit choice, and sign-out keeps changes that have not reached the account.
• •Army imports validate their contents and recalculate points, including older weapon formats. Shrinking a unit removes unavailable equipment, Undo stays with the correct army and restores Commander and transport links, and clearing an empty collection keeps its recovery backup.
• •Damage estimates apply Blast, Tracking, Accurate, Burrowing, Psi and Engine Killer consistently. Calculations finish reliably when opened or reopened, and the target popup fits narrow screens.
• •All linked detachment reference pages are included in the published site, including transports and Legends. Rules tables explain their markers and page descriptions match their content. Search recognises preds, tacs, termies, termie and dreads while keeping exact names and selected filters authoritative. Invalid addresses show a readable error page with links back to Home and Reference.
• •Menus fit tablet and short-screen layouts, close with Escape and release scrolling when the layout changes. Phone settings and weapon controls stay readable, and an unnamed army cannot be saved accidentally.
• •Footer links and quote credits are readable in both themes. Home respects Reduce Motion, visible form labels name their fields, and reference tabs support arrow keys, Home and End. The damage calculator keeps keyboard focus inside while open and returns it to its button when closed.
• •Selected phone-menu labels are easier to read in Light mode, and Become a Supporter now takes you straight to the membership page

• •Rule cross-links open the right rule. Following a link from a weapon trait to a special rule used to leave you on the Weapon Traits tab, showing traits that merely mention the rule you asked for — with no sign anything had gone wrong. It now switches to the tab that holds the rule
• •Printed reference pages keep their content. Printing the rules quick reference silently dropped every section heading, and Army Lists and Special Rules lost their expanded bodies — all of it prints again
• •The reference section reads as one section. Every page now shares the same content width instead of jumping between two, searches that find nothing say so once in one voice, and the formation, unit and detachment pages share one header and one stat block
• •Starting a battle no longer breaks the Game Companion. A unit your list references but the data can't resolve is now skipped with a warning instead of taking the whole page down
• •"Play this list" is back. Open any saved army's Share, Print & Export hub and you can start a game with that army already selected
• •On iPhone, the Print button works on the first tap. It used to do nothing until you tapped it a second time
• •Live games start reliably. Creating one can no longer hang on "Creating…" forever — it now tells you if the connection failed and lets you try again — and your cloud army lists load on a fresh browser instead of coming up empty
• •Printed reference pages are readable. The dark panels — army rules, the core list-building bars, unit and weapon cards — now print as dark text on paper instead of a solid block of ink
• •If your device switches between light and dark while the app is still loading, the app now follows it instead of staying on the old theme
• •Builder tidy-up: the round "?" help button is the same shape in every compliance panel, and on a phone a long legion name no longer prints over the badges next to it
• •Import fixes: an upgrade whose name contains another upgrade's name (like "Additional Auxiliaries with Flamers") now imports as the model you actually picked, casual words like "done" no longer get read as a paint stage, and a project goal whose army list or box has been deleted says so instead of quietly showing 0%

Legion Companion is completely free to use with no ads. It is a fan-made project built for the Legions Imperialis community. However, hosting and running the app is not free — if you find it useful, please consider supporting the project to help keep it going.

Your army lists, collection, and game data are saved on the device you're using, and the app keeps working if your connection drops mid-session. Sign in and cloud sync keeps everything in step across all your devices. You can also install it to your home screen like an app. (A full offline cold-start isn't supported yet.)

Legion Companion supports Legiones Astartes, Solar Auxilia, Mechanicum Taghmata, Dark Mechanicum, Questoris Familia, Collegia Titanica, and Strategic Assets — covering all current Legions Imperialis factions and updates.

Yes. You can generate a shareable link for any list, print game-ready tracker sheets, or export lists as text. Cloud sync is also available so your lists follow you across devices.

Any modern device — phone, tablet, laptop, or desktop. The layout adapts to each screen, and touch, mouse, and trackpad are all fully supported, so it works just as well at the table as it does at your desk.
