Fortress workshop

Castle Architect

Sketch fortress blueprints on a tactical grid, run sieges against your own walls, and archive every assault rating.

Inside the keep

Three rooms of the app — canvas, theater, and memory — written as one continuous field journal.

Blueprint canvas

Place walls, towers, gates, and traps cell by cell on a readable grid. Quick presets give you a defensible spine in seconds, and the structure palette spells out placement hints so every piece earns its coordinate. Defense totals and piece counts update as you refine the plan.

Attach reference photos to a blueprint kit or record a short voice note after a memorable assault — both stay on your device alongside the layout you were studying.

Siege theater

When a blueprint feels ready, march an assault against it. The siege theater replays pressure on your design so you can see where the curtain wall thins or where a tower gap invites trouble. Adjust siege speed in keep settings when you want time to read each phase.

Vault and archive

Save finished plans in the blueprint vault, duplicate favorites, and reload them when inspiration returns. The siege archive stores past outcomes with ratings, duration, and notes — a ledger of lessons from every run.

Field captures

Screens from the keep — thumbnails inline, like margin sketches in a commander’s log.

Onboarding introduces the sectors of the keep before you place your first stone.

The blueprint canvas is where defense totals climb as you commit each structure.
