Some rooms are always too hot. Tiang tells you which ones, before you build. Draw your floor plan and Tiang works out how the house behaves: the sun on your roof, the heat coming through your walls, the air in every room, hour by hour, using real weather for where you live. Other home design apps show you how a room looks. This one shows you how it will feel. ▸ FIND THE HOT ROOM See every room's temperature through a whole day. Watch the afternoon sun move across the house and see which rooms heat up, which stay cool, and which never cool down at night. Then find out why: the way it faces, the windows, the roof colour or the insulation. ▸ PICK THE RIGHT AIR CONDITIONER Tiang works out how much cooling each room really needs, from its size, its walls, its windows and your local climate. So you don't end up with an air conditioner that's too big or too small. ▸ TRY A FIX, THEN RUN IT AGAIN Swap brick for a lighter wall. Add roof insulation. Move a window. Change the roof colour. Run it again and see what changed, or put the two versions side by side. ▸ WINTER TOO It works the other way round as well. See where heat escapes, how long a room stays warm after the heating goes off, and how much a better wall or roof would help. ▸ DAMP BEFORE IT BECOMES MOULD See which rooms are at risk of condensation, so you find the cold corner before the mould does. ▸ AND THE WIFI See the WiFi signal through your real walls: which room it drops out in, and which wall is to blame. ▸ WHAT IT COSTS TO RUN Estimate your electricity bill from the house you drew: appliances, lights, heating and cooling. Put solar panels on the roof and see how much they would produce and how soon they would pay for themselves. ▸ WHAT YOU CAN DRAW - Walls, doors, windows, arches and balconies, all at real measurements - Several floors, with stairs and your own roof shapes - Furniture, fans, air conditioners, heaters, lights and wiring - Walk through the finished house in 3D - Take a photo of a printed floor plan and Tiang traces it for you - Metric or imperial - Works offline. Drawing and saving are always free ▸ NO PLAN YET? Pick a house style and Tiang draws a starting floor plan you can change, then test like any other. (Beta) ▸ ON EVERY DEVICE, TOGETHER Tiang runs on iPhone, iPad and Mac. Sign in and your projects sync across all of them, and with any phone or tablet you use Tiang on (cloud sync is part of Tiang Pro). You can also invite someone to work on the same house with you. ▸ TAKE IT WITH YOU Export a PDF with the floor plans, a list of everything in the house and your results, for your builder, a client or your own records. ▸ FREE AND PRO Drawing, editing and saving are free and unlimited, always. Every month a free account also gets some simulations, a timelapse, a PDF export and a generated plan. Tiang Pro removes the limits, lets you compare two versions of your house side by side, and adds cloud sync and sharing. Tiang Pro is a subscription. It renews automatically unless you cancel at least 24 hours before the end of the current period, and you can manage or cancel it at any time in your Apple Account settings. ▸ A NOTE ON THE RESULTS Tiang's results are estimates to help you compare options. They are not a building-regulations check, and they don't replace an architect, engineer or electrician.

It now matches your drawing, and the north arrow points the right way. ### 1.3.1 — 2026-10-13 A fresh look - In the editor, the tools sit in a new bar. It shows icons, and the tab you open shows its name. On iPad held sideways, the tools and their drawer share one card down the side. - Tap outside the drawer to close it. - The floor buttons now open a floor card: every floor with its rooms and ceiling, rename or delete a floor, and add one above or a basement. - In Simulation, the project list shows each project with its picture and size, and a search box when you have more than 8. - On iPad held sideways, settings open as a panel on the side you tapped, instead of covering the screen. - On Home, the "By Name" row stays at the top while you scroll. Appearance - A new Appearance screen in Profile, just above App Settings: choose System, Light or Dark. - Tiang Pro adds Transparent: the tab bar and the editor's bars float over the page as glass. Opacity sets how see-through the glass is, from 5% to 100%. Transparent is on for Pro accounts, and you can switch it off in Appearance. - On iPad held sideways, the tab bar sits on the right. With Tiang Pro you can move it to the left or the bottom. Backup & Restore (Tiang Pro) - Tiang keeps snapshots of your projects in the cloud: one every 12 hours, plus any you save with Back Up Now. Restore any of them from Profile. - A new Sync switch in Profile pauses syncing on the iPhone or iPad you're using, until you turn it back on. Air conditioning and heating - AC sizes come in BTU/h, kW or PK. A new unit starts on Auto, the shop size that suits its room, and its electricity follows the size you pick. - Tiang Pro adds Custom, for the exact sizes and electricity on your unit's spec sheet. - One outdoor unit now serves up to 4 indoor units. Choose which one each indoor unit uses under Connected To, and see its refrigerant pipe go through the outside wall in 2D and 3D. - The Electricity simulation now works out what each AC and heater really uses, inverter or not, instead of counting it at full power. iPhone Duo - Tiang fits iPhone Duo folded and open: the tab bar sits in the side strip next to the clock, and nothing hides behind it. ## Apps similar to Tiang | App | Rating | Price | Category | | --- | --- | --- | --- | | [Build It Yourself: Room Design](https://appshunter.io/ios/app/build-it-yourself-room-design/id6818286088) | — | Free | Graphics & Design | | [PlanEditor](https://appshunter.io/ios/app/planeditor/id6809376563) | — | Free | Graphics & Design | | [UglyPDF: AI Invoice & CV Maker](https://appshunter.io/ios/app/uglypdf-ai-invoice-and-cv-maker/id6810750390) | — | Free | Graphics & Design | | [Arti — Plan 2D & 3D](https://appshunter.io/ios/app/arti-plan-2d-and-3d/id6796981673) | — | Free | Graphics & Design | | [Room Decorator・Interior Design](https://appshunter.io/ios/app/room-decoratorinterior-design/id6776314330) | — | Free | Graphics & Design | | [DOMEON — Order Your Home](https://appshunter.io/ios/app/domeon-order-your-home/id6761807679) | 5.0 (1) | Free | Graphics & Design | ## Related topics [planos de casa gratis](https://appshunter.io/ios/topics/planos-de-casa-gratis) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
