A Floor Plan App Built for the iPhone Duo

RoomSketch3D knows how your iPhone Duo is folded. Open flat, the whole plan fills the big screen. Half-open on a table, the plan sits on top and Furnish, Materials and Symbols sit underneath. Closed, the tools move to the side column.

RoomSketch3D is built for the iPhone Duo. The floor plan editor knows whether the phone is open flat, half-open or closed, and lays itself out for each. A floor plan is a wide drawing full of small numbers, so the Duo's 7.6-inch inner display is the best phone screen there is for it: a whole apartment fits with its wall lengths readable, and the catalog doesn't have to cover half the plan.

Stand the Duo half-open on a table and it works like a little laptop: the plan sits on the upper half, and the lower half under your hands holds Structural & Interior, Furnish, Materials and Symbols as tabs. Tap a sofa below and it lands on the plan above, with nothing popping up over your drawing. Closed, the editor's tools move into the column beside the clock, the way Apple lays out toolbars on the Duo's outer screen, so the plan gets the full height.

It's the same RoomSketch3D you'd use on a computer or any other phone: draw to scale, furnish from a large catalog, check walkways with Smart Flow Check, and walk through the room in 3D. Your designs follow your account to every device, and one purchase covers them all.

What you can do

Whole plan, open flat

The editor fills the inner display edge to edge, upright or sideways, with every measurement readable.

Tabletop layout

Half-open on a table: plan on top, Structural & Interior, Furnish, Materials and Symbols as tabs below.

Tools down the side

Closed, the toolbar moves to the side column so the plan uses the full height of the outer screen.

Re-fits as you fold

Fold, unfold or turn the phone and the whole plan fits the new screen.

Nothing on the crease

Half-open, the plan stops above the fold and the tabs start below it.

Same designs everywhere

Start on the Duo, finish on a computer: one account, one purchase.

How it works

  1. 1

    Get the app

    Install RoomSketch3D from the App Store (version 1.1.0 or later has iPhone Duo support) and sign in with Apple or Google.

  2. 2

    Open it flat to draw

    Draw the walls or start from a template with the phone open; the plan fills the big screen.

  3. 3

    Stand it half-open to furnish

    Set the phone on a table half-open. Pick furniture, materials and symbols on the lower half and watch them land on the plan above.

  4. 4

    Close it for quick checks

    On the outer screen the tools sit in the side column, so the plan still gets the full height.

Good to know

  • Open flat and held sideways is the widest view for drawing, measuring and the 3D walkthrough.
  • Half-open, the floor picker is tucked away; tap Exit fullscreen on the toolbar to switch floors.
  • The editor also runs in Safari at app.roomsketch3d.com, but only the app knows how the phone is folded.

Frequently asked questions

Is RoomSketch3D optimized for the iPhone Duo?

Yes. The iPhone app (1.1.0 or later) lays the editor out for each pose: the whole plan on the open screen, a tabletop layout with the plan on top and the catalog below when the phone stands half-open, and the toolbar in the side column when it's closed. Every fold, unfold or turn re-fits the plan.

Does RoomSketch3D have a tabletop mode on the iPhone Duo?

Yes. Stand the phone half-open with the fold running across: the floor plan moves to the upper half, and Structural & Interior, Furnish, Materials and Symbols open as tabs on the lower half, with Furnish first.

Does it work on the iPhone Duo's outer screen?

Yes. Closed, it works like any iPhone, with the editor's tools in the column beside the clock so the plan uses the full height.

Can I use it in Safari on the iPhone Duo?

Yes, at app.roomsketch3d.com, with the same layout on the open screen. Safari doesn't tell web pages how the phone is folded, so the tabletop layout and the side tool column are only in the app.

How much does it cost on the iPhone Duo?

It's a one-time purchase of $19.99 on the web (the App Store shows its price in your local currency), not a subscription. One purchase covers your account on the iPhone Duo, other iPhones, iPad, Android and the web.

Has it been tested on a real iPhone Duo?

It was built and tested in Apple's iPhone Duo simulator, which reproduces both displays and the fold. If a pose looks wrong on your phone, report it from Support in the app so it can be fixed.
