Best Apps for Interior Design in 2026: 9 Apps Compared

Planner 5D is the most balanced option for someone who wants to draw a floor plan, furnish it and see it in 3D without learning professional software. Its site describes 2D and 3D design on web and mobile, a furniture library of more than 8,000 items on the homepage and 10,000+ on the pricing page, mood boards and a shopping list with cost estimates.

The free plan gives you unlimited projects with access to about half of the furniture catalog. The catch is what it leaves out: uploading an existing floor plan, standard renders, the Budget Widget and AI Studio credits all need a paid plan. Premium is listed at $19.99 monthly or $59.99 yearly, and the page also shows a lower per-month figure in its header, so check the checkout screen before you commit. Professional is $49.99 monthly or $399.99 yearly and adds 4K renders without watermarks and CAD export.

For a single room or a move-in plan, Premium for one month is usually enough. The iOS app carries a 4.4 rating from more than 42,000 App Store ratings.

RoomSketcher leans toward accurate layouts rather than decorating inspiration. That makes it a good fit when you are planning a renovation, checking whether a sofa fits, or handing a plan to a contractor.

The free plan keeps up to 10 projects with basic 2D and 3D tools, limited furniture and symbols, and watermarked 3D snapshots. It also includes two one-time credits and one free AI floor plan conversion. Pro costs $12 per month billed annually ($144 per year) or $24 month to month, and adds the full furniture library, Live 3D, measurements and printing to scale. Team starts at $35 per month billed annually for five users.

Pay-per-use options exist too: the pricing page lists 2D or 3D renders at $4 each and professional floor plan orders at $38 per floor. If you only need one polished picture, that can be cheaper than a subscription.

Homestyler markets itself as free 3D interior design software. Its homepage lists a cloud-based floor planner, more than 10 million branded 3D furniture models, over 500 design templates, and AI features such as turning a 2D plan into an editable 3D model and generating moodboards.

The Basic plan is free and includes unlimited 1K renders. Anything sharper, such as 4K renders, video rendering or extra AI credits, requires coins, one-off purchases or a subscription. Paid plans start low: Pro+ from $6.8 per month with 75 renders each for 2K and 4K, and Master+ from $11.8 per month with unlimited 4K image rendering. Those are the starting prices on the pricing page, so confirm the billing period at checkout.

It is a good choice if you want rich visuals on a small budget and do not mind a busy interface with many features. The iOS app has a 4.4 rating from about 5,500 App Store ratings.

IKEA Kreativ solves a specific problem: will this sofa, shelf or kitchen island look right in my actual room. According to IKEA's launch announcement, the Scene Scanner inside the IKEA app turns a series of room photos into an interactive 3D replica with accurate dimensions. You can erase furniture that is already there, drop in IKEA products and swap alternatives.

IKEA says the full room design experience is free for US customers and that designs are stored in the cloud, can be saved to an IKEA account and added to your cart. You can also start from more than 50 3D showrooms on the IKEA Kreativ page if you would rather borrow a layout than scan your own.

The limit is obvious: it is a shopping tool for one retailer. Treat it as the last step, after you have settled on a layout somewhere else. Because the announcement dates from 2022, we would check the current IKEA app for which devices and countries are supported.

Sweet Home 3D is the answer for people who dislike subscriptions. Its site describes a free application for drawing your floor plan, arranging furniture and viewing the result in 3D. The full version includes more than 10,000 models and 400 textures, and you can produce photo and video renderings.

It runs on Windows, macOS and Linux, and the site says it can also be used online in any WebGL-capable browser. The project is open source and hosted on SourceForge under the GNU General Public License. The page lists version 7.5, last updated May 5, 2025.

The trade-off is effort. There is no mention of AI floor plan conversion or automatic styling, so you place walls, doors and furniture by hand. If you are patient and want a no-cost, no-account tool, it is hard to beat.

Houzz is where many design projects start, not where they get drawn. The app listing describes more than 20 million photos of finished interiors and exteriors, which you can sort by style, location or room and save into collections to share with family or a professional.

It also lists more than 3 million home improvement professionals, with reviews and photos of past work, plus editorial articles and a Q&A style advice section. The homepage lets you find pros by category and shows cost guides. The App Store listing shows a 4.8 rating from over 320,000 ratings.

Do not expect to build a floor plan here. The pricing page on the site is for Houzz Pro, which is software for contractors and designers with a free 30-day trial, not for homeowners. Pair Houzz with a planning tool from this list.

Havenly is a design service rather than an app. You take a style quiz, get matched with a designer, and receive a design plan with a rendering of your space and a shopping list. The site lists online design starting at $159 (shown as $199 before the discount) and in-person design starting at $499.

There is also a free AI interior design option to get started on your own, though the page gives no pricing detail for it. Havenly says "Love your design or it's free," and members get discounts on hundreds of brands. In-person designers serve cities including Denver, Houston, Austin, Dallas, Chicago and New York.

Havenly suits someone who knows the room is not working but cannot picture the fix. The iOS app has a 4.4 rating, though the rating count is small compared with the other apps here.

Decorilla is the premium end of online design. You pick a package, designers submit concepts, and you work one-on-one with the one you prefer. You receive a 3D model, a color palette and a floor plan.

The site lists Bronze at $599 ($479 with the current promotion), Silver at $859, Gold at $1,099 and Platinum from $1,980, plus hourly help at $119 to $500 per hour. It also advertises up to 45% off at more than 350 furniture stores and a satisfaction guarantee.

This is not for a quick weekend refresh. It makes sense for a whole-room or whole-home project where a wrong furniture purchase costs far more than the design fee.

SketchUp is a general-purpose 3D modeler that designers use for interiors, built-ins and renovations. It is not a drag-and-drop decorator. You model walls, cabinets and furniture yourself, which gives you control that simpler apps cannot match.

The pricing page lists Go at $10.75 per user per month billed annually, covering essential 3D design for iPad and web. Pro is $33.25 and adds the full desktop modeler, LayOut and more than 1,000 extensions. Studio is $71.58. The only free offering listed is SketchUp for Schools, which needs a Google Workspace for Education or Microsoft Education account.

Choose SketchUp when you need to design a custom kitchen or a piece of furniture that does not exist in any catalog. For plain room layouts, it is more tool than you need.
