Snap any room. Empty, half-empty, or fully lived-in.
Open Furnish, point your camera at a room, and tap. Empty bedroom with bare walls? Half-finished living room with a couch and not much else? A kitchen that has been the same for a decade? All three work. Furnish does not need a clean slate; it works with whatever you have.
The capture flow shows a quick guide on first use: stand in one corner so two adjacent walls are visible, hold the camera at eye level, and let in as much daylight as you can. That is the entire ask. No measurements. No wide-angle lens tricks. The closer the photo is to how you actually see the room, the better the redesign.
If you upload from your camera roll instead of capturing fresh, that works too. Furnish accepts standard JPEG and HEIC photos at any modern phone resolution.
