The Android app: getting started
Everything you need to get going with RoomSketch3D on Android.
The Android app is the full RoomSketch3D editor on a phone or tablet: the same designs, catalog, Smart Flow Check, 3D view and image exports as the web, with a layout arranged for a touch screen. It's included in the one-time purchase — sign in with the account you already use and everything is there.
This page covers installing and signing in, how the phone layout is organised, the touch gestures, and what you do on the web instead.
Step by step
- 1
Install and sign in
Search RoomSketch3D on Google Play and install. Open it and tap Continue with Google (the only sign-in in the Android app). If your account uses Apple sign-in or an email code, the Android app can't open it: use it on the web at app.roomsketch3d.com, or email roomsketch3d@immex.tech to move it to your Google account (see Sign in or create your account). If you've already purchased, the app is unlocked as soon as you sign in; if not, you can buy in the app through Google Play. Your designs list appears on the first screen.

The plan and the pill row
The plan fills the screen. Along the bottom is the pill row: Structural & Interior (walls, doors, windows, stairs, fireplaces), Furnish (the catalog), Materials (flooring, wall and ceiling paints, Picture Gallery and the Tile Planner) and Symbols. One tap opens each as a sheet that slides up from the bottom. Walls are edited by tapping them on the plan (see Edit walls on the plan).

The Furnish sheet
Tap Furnish: the catalog opens as a bottom sheet with the search box, room chips and size filters. Tap a tile, then +Add, and the piece lands in the room; the sheet drops so you can place it.

Build and Materials
Structural & Interior holds the build tools and doors/windows in one sheet; Materials opens one popup with Surfaces, Picture Gallery and Tile Planner tabs (details below). Show or hide labels and measurements with Layers, the first icon in the toolbar row above the plan; Plan Settings (top row) holds the plan's Layout, Rotation, exterior Walls placement and Ceiling height.

Touch gestures
Drag a piece to move it; the drag magnifier shows exactly where it lands. Pinch to zoom, two-finger drag to pan, two-finger twist to rotate the selected piece. Tap a piece for its inspector. In 3D: one finger rotates, two fingers pan, pinch zooms; walk mode uses the on-screen joystick.

Floors, paint and tiles: the Materials popup
Tap Materials in the pill row. The popup opens on Surfaces, with Flooring Material, Wall Paints and Ceiling Paints underneath: the live 3D view sits on top, the small plan below it. Tap a room (or a wall) on the small plan and choose a finish; the 3D view shows it straight away. Picture Gallery holds your photos for picture frames, and Tile Planner counts tiles and cuts for a room. Close the popup with the ×. See per-room flooring, paint your walls, paint your ceilings and the Tile Planner.

What's different from the web
Exports: the app's Share / Export menu has Share with a link, the image (PNG/PDF) export and print, and Photorealistic AI Renders. The GLB 3D model, DXF CAD file and Backup (JSON) are exported on the web at app.roomsketch3d.com, and From Backup on Home is web-only too. Open the same design there; it's already synced. Sign-in: Continue with Google only (Apple and email code are on the web). Codes: Gumroad licence keys and gift codes are redeemed on the web. AR room scanning is iPhone and iPad only.
Tips
Tablets
On a tablet in landscape the app switches to the desktop layout with side panels — the same as the web.
Photo to floor plan
Use the phone's camera for Use Room Photo and Floor Plan Image: snap the plan on the wall of a rental office and trace it on the spot.
Common mistakes
Signing in differently on the phone
Google here, Apple there: separate accounts, empty list. On Android only Google sign-in is available, so if you plan to use Android, use Continue with Google on your other devices too.
Looking for AR scan on Android
It's an iPhone/iPad feature. Measure with the tape measure or type room dimensions instead.
