Skata Upans

Does every sleeping room in your home have two genuinely independent ways out? Most households have never checked — and paper fire-escape grids do not compute that answer. Skata Upans does. Draw your floor plan room by room, add every door and window with real measurements, and Skata Upans instantly proves whether each sleeping room has two escape routes that share no hallway and no opening. The built-in escape-opening solver checks every window against US (IRC) or UK (Approved Document B) residential codes, reporting the exact shortfall in millimetres when a window falls short. Smoke-alarm coverage is verified against nine placement rules, with a plain-English explanation of every gap and a precise shopping list of exactly what to buy and where. Run a timed evacuation drill with your household: pick a blocked-exit scenario, assign each person a start room, and record arrivals at your meeting point. The debrief computes per-person splits, identifies the slowest route, and links directly to the fixes that matter. The Case Library adds 48 hand-crafted floor-plan puzzles across five difficulty tiers — each hiding exactly one room that cannot get out — so you learn to spot escape problems in any home. Skata Upans runs entirely offline. No account, no subscription, no data leaves your device. Everything is computed live as you edit — fix a window measurement and every route, alarm rule, and fix-list item updates instantly. Because knowing two ways out is not something you should have to guess.
