Naku Trail

Moving furniture into a new home — or buying a piece you love — should not end with it stuck in the stairwell. Naku Trail calculates whether your sofa, wardrobe, bed frame, or piano will physically pass through every door, corner, and staircase on its way to the room, before it ever leaves the shop or the moving van. Build a route by adding the passages your furniture must travel: front doors, hallway corners, doors off narrow halls, staircases with landings, and lifts. Enter the real measurements — door width, hall depth, ceiling height — and choose your piece from twelve common presets (sofa, wardrobe, mattress, fridge, upright piano, and more) or enter custom dimensions. Naku Trail's geometry engine instantly tells you whether each passage is a pass or a jam, and gives you the exact clearance at the tightest point. When something jams, the app shows you why. Open the interactive diagram, slide and rotate the furniture with your fingers, and see precisely where it catches the wall. Then try the Fix It suggestions — removing the door from its hinges, taking off furniture legs, or clearing a door stop — and watch the verdict update in real time. When everything fits, the app generates a step-by-step maneuver card you can share with your removal team, covering carry angle, adjustment order, and when to begin each swing. No account required. No internet connection needed. No data collected. Everything runs on your device, privately, in centimetres or inches. A built-in sample route lets you explore all features without entering a single measurement. Puzzle mode adds 30 geometry challenges across hallways, landings, and obstacle rooms — a practical way to sharpen your moving instincts before the big day.
