The 8 Best Interior Design Apps in 2026 (Free & Paid)

There are hundreds of interior design apps now, and honestly most of them blur together. Some redesign a photo with AI, some let you build a room in 3D, some are really just furniture shops with a camera bolted on. The trick isn't finding an app — it's finding the one that matches what you're actually trying to do. I've spent real time in these, and below are the eight I'd genuinely recommend, sorted by what each one does best, so you can skip straight to yours.

Small honesty note: you're reading this on House AI's blog, so House AI is my top pick — but every app here earns its place, and I'll tell you plainly when another one is the better fit for your project.

How to Pick an Interior Design App

Before the list, ask yourself one question: do you want to restyle a room, or plan one? If you want to see your existing space reimagined in a new style — fast, from a photo — an AI redesign app is what you want. If you want to move walls, set exact dimensions and lay out furniture to scale, you want a 3D planner. Some apps do a bit of both, but most are great at one and average at the other. Match the tool to the job and you'll be far happier.

The 8 Best Interior Design Apps in 2026

1. House AI — Best Overall (AI Redesign)

House AI is the easiest way to see your real room transformed. You upload a photo, pick from 35+ styles, and get a photorealistic redesign of that same space in about 15–25 seconds at up to 2K HD. It's not interiors-only either — it handles exteriors, gardens, wall paint and flooring from the same simple workflow. The standout feature is Shop from Image (beta): it detects the furniture in your render and finds real, in-stock products with prices and links, so the design becomes a shopping list, not just a pretty picture. There's a free daily generation with no credit card. Best for: anyone who wants a fast, realistic redesign of a real room — and the option to buy the look.

2. Houzz — Best for Inspiration & Shopping

Houzz is the giant of the category — millions of high-quality room photos, a huge product marketplace, and a directory of real professionals. It's less about AI-generating a design and more about browsing endless inspiration, saving ideas to boards, and buying the exact pieces you spot. If you love scrolling beautiful rooms and shopping the look, it's hard to beat. Best for: idea-gathering and buying real furniture and decor.

3. Planner 5D — Best for 3D Floor Plans

Planner 5D is a full design suite for building rooms and homes in detailed 2D and 3D, with a large catalog of items and surprisingly beginner-friendly controls. If you want to lay out a space to scale — walls, windows, furniture positions — rather than restyle a photo, this is a great pick. Best for: planning a room or whole home layout from scratch.

4. Homestyler — Best Free 3D Design

Homestyler offers a lot of 3D floor-planning power with a genuinely usable free tier and a big furniture library. There's a slight learning curve, but for DIY layouts, moodboards and photorealistic 3D renders without paying up front, it's one of the best free options going. Best for: free 3D room planning and rendering.

5. Morpholio Board — Best for Mood Boards

Morpholio Board is a favorite of professional and aspiring designers for building polished mood boards — drop in products, pull colors, arrange furniture and materials into a shareable board. It's less about generating a room and more about curating one. Best for: designers and detail lovers who think in mood boards.

6. Havenly — Best for Hiring a Real Designer

Havenly pairs you with a real human interior designer for a flat fee — you share your space and style, they send you a plan and a shoppable product list. If you'd rather hand the project to a professional than DIY it, Havenly is the most app-native way to do that. Best for: people who want expert help without a full in-person designer's price tag.

7. DecorMatters — Best for Mobile & Community

DecorMatters is a fun, mobile-first app that blends design tools with a social community and shoppable products. You can restyle a space, join challenges, and get feedback from other users. It's casual and playful rather than precise. Best for: mobile users who enjoy a gamified, community-driven experience.

8. IKEA Kreativ — Best for Furniture Placement (AR)

IKEA Kreativ lets you scan your room and drop true-to-scale IKEA furniture into it with AR, so you can see how a specific sofa or shelf actually fits before you buy. It's tied to IKEA's catalog, but for visualizing real products in your real space, it's excellent and free. Best for: checking how furniture fits before you commit.
