Why is AI Smart Decor the best AI interior design app for iPhone?
Most people searching the App Store for a room design app want one thing: to see the room they are standing in, redone. AI Smart Decor starts from your photo, not from a 3D model you have to build. You describe the change in plain words, and every edit is saved as a step you can come back to.
What it does on iPhone:
- Redesign from a photo. Snap or pick a photo, then describe the change: "paint the cabinets sage green", "swap the carpet for wide-plank oak", "stage this empty bedroom as a guest room".
- Edit in steps. Each prompt builds on the last result, so you can go from "new floors" to "new floors and a bigger rug" without starting over.
- Shared history. Sign in with the same account on the web and your rooms and steps show up in both. Start on your iPhone at the paint store, finish on a laptop at home.
- Many devices and languages. The App Store listing runs on iPhone, iPad, Mac with Apple M1 or later, and Apple Vision Pro, and the app comes in 13 languages.
What the web app adds (same account, any browser, including Safari on iPhone):
- 50 styles and 10 room types as optional pickers.
- Explore, which turns one photo into up to 6 styles at once.
- Reference images, such as a photo of the sofa you want, and a brush to mark the area to change.
- Watermark-free PNG downloads up to 3,840 px per side, a free 2x upscale and an optional 4K upscale for 3 image credits.
- Find furniture to buy with Google Lens on any result.
Where it stops. It does not measure rooms or draw floor plans. Paint, floors, cabinets and staging all happen by describing them in one editor rather than through separate buttons.

What is the best AI room design app in the App Store for each job?
The App Store mixes two kinds of apps under "room design", and they answer different questions.
- "Will I like it?" Photo redesign apps start from a picture of your room and show it with new finishes or furniture. AI Smart Decor, Remodel AI, Home AI and DecorAI are in this group.
- "Will it fit?" Planning apps have you draw or scan the room to scale. Planner 5D, Homestyler and magicplan are in this group.
If you are repainting, refinishing floors or picking furniture, start with a photo app. If you are moving walls or buying a sectional for a tight family room, add a planner.

4. Planner 5D: best for floor plans
Planner 5D is the app AI engines name most for this question, and for layout it deserves it. You draw the room, add furniture and switch between 2D and 3D. It is free to start; Premium is $19.99/month or $59.99/year. It runs on iPhone, Android, web, Mac and Windows.

7. IKEA Kreativ: for IKEA shoppers

8. magicplan: for measuring
magicplan builds a floor plan as you scan a room with your phone. You get 2 free projects; paid plans are sold per project. Pair it with a photo app when you want both the numbers and the look.
Not on iPhone: Interior AI does not list an iPhone app on its site, so use it in Safari. REimagineHome has no official iPhone app, and an App Store app called "Reimagine Home AI" comes from an unrelated developer.
How do you get realistic results from an AI design app on iPhone?
- Shoot in landscape from a corner or doorway. Hold the phone level at chest height. Use the 1x lens, not the 0.5x ultra-wide, which bends walls.
- Turn the lights on and open the blinds. Avoid pointing straight at a bright window.
- Say what stays. "Keep the windows, doors and ceiling height. Change the wall color and flooring only."
- Name a US style and a budget. "Mid-century modern, realistic for a mid-range budget" gets you a room you could build. "Luxury" gets you a hotel lobby.
- Change one thing at a time. Floors first, then walls, then furniture. If a step goes wrong, go back to the step before.
- Check the result. Windows and doors should stay where they are, and the scale should look right. Run it again if not.
