Muster Army Builder

Tabletop wargame list builder

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Muster is a fast army-list builder for miniature tabletop wargames. Muster ships empty and imports the community-maintained datasets you already use, so your unit and rules data always comes from your own source — not from us. • Build legal lists — add units, set a points limit, and watch a live budget as you go. • Detachments & enhancements — pick detachments and enhancements with automatic points/slot enforcement. • Import your data — load community dataset files at runtime; nothing is bundled. • Dice roller — D3/D6/D12/D20 with history, for quick in-game rolls. • Collection tracker — record which miniatures you own and their paint status. • Campaign tracker — track your force across a narrative campaign with rank and experience progression. • AI list coaching (Pro) — a read on your list's strengths, weaknesses and swaps, or a plan for a specific opponent. • No account, no sign-up — your lists stay on your device. Muster needs a connection twice: once to download a dataset, and again if you use the AI features, which send only your list text for analysis. Everything else works offline. Muster Pro is a one-time purchase, not a subscription. It unlocks unlimited army lists (free covers one), Rate My List, matchup analysis, and all future Pro features. Not affiliated with, licensed by, or endorsed by any game publisher. For use with your own rulebooks and community data.

  • This app hasn’t received enough ratings or reviews to display an overview.

Muster now flags required choices your units still need, with one tap to fill in the defaults. Paste an army list as text to import it, and share your lists. Pro adds plain-text and tournament export formats. Also fixes Kill Team catalogues being skipped on import.
