Why we made this
We didn't want to move the sofa just to find out.
We wanted a longer TV console for a new 77 inch TV. The way our living room is laid out, the only sure way to know was to start shifting a heavy sofa. So we measured the walls on a phone and hoped. It fit, but we had no way of knowing until it did.
Then we wanted the baby's cot beside our bed. Same problem, and this time we gave up: too many things to move just to find out.
So we built the app we wanted both times. Measure the room once and try it on screen. You'll see every piece that has to move, so you can decide if it's worth the hassle before you lift anything.
