Short answer. If you plan on a computer and want free, open source software that works offline, Sweet Home 3D is the better choice: it runs on Windows, macOS and Linux and in a browser, draws precise plans and lets you walk through them as a virtual visitor. If you plan on an Android phone and want your real flat with real furniture, Flatwalk is the better choice: it reads a photo of your floor plan or scans the rooms by their corners, furnishes them with real shop pieces at true size, adds lights and the sun for your address, and lets you walk through at eye level, free for one flat.

What Flatwalk does that older planners skip
Lights
Add ceiling lights, lamps and LED strips and see the room lit as you walk through it, not only in a rendered picture.
Your flat in its city
Give the address and the street and buildings around you appear in 3D where the map has them, so you see what is outside each window.
Sun for your address
The light falls where it really falls, by date and hour, while you walk.
One piece, in your own room
Through the live camera or in a photo of the room, stand a sofa on your own floor at its true size before you buy it.
Detail
Dozens of door and window types, and kitchens, wardrobes and bathrooms built piece by piece, with real floors, tiles and paints.
Made for a thumb
Tap a wall, a door or a sofa and the choices for that thing appear. It is a phone app first, not a desktop program made smaller.
Swipe for more. Every picture is the app itself.
One flat, free
Most people plan one home. For that, Flatwalk costs nothing: no trial clock, no subscription and no card. Draw the plan or scan the rooms, measure, furnish with real pieces from real shops, set the lights and the sun, and walk through it as often as you like. Each AI tool gives one free try: a flat from a photo of your floor plan, an AI photo of a room, a piece of furniture made from a shop link. A membership is for people who want more flats or more AI, and it bundles all of it in one price.
