The App Store and Play Store are full of home design apps that claim to be free. In practice, most of them let you browse inspiration or set up an account for free, then wall off the actual AI redesign features the moment you try to use them.
This guide focuses on what happens after you download. We test the free tier of each app to determine: how many renders can you actually get for free? Do mobile-specific features like camera integration and AR work without paying? And which apps are worth the storage space?
The Mobile-Specific Advantage
Mobile home design apps can do things desktop tools can't:
- Instant photo capture: photograph your room and upload in one step, no file transfer
- AR overlays: some apps use your camera to place virtual furniture in your actual space
- Spatial measurement: newer apps use LiDAR (iPhone Pro) or ARCore (Android) to measure rooms automatically
- Portrait and landscape flexibility: shoot rooms in the orientation that captures the full space
These features matter. An app that doesn't use them is essentially just a browser tool with a worse interface.
App-by-App Breakdown
AI Smart Decor (Web App — iOS & Android)
Rating: Browser-based PWA | No app store download required
AI Smart Decor is a progressive web app, meaning you access it through your phone's browser rather than downloading from an app store. This is actually an advantage: no storage space used, always the latest version, and no app store approval delays.
Free tier test results:
- Upload a room photo: works immediately, no account needed to preview
- Style options on free tier: 20+ styles available
- Renders before hitting paywall: several — more than most native apps
- Output quality: photorealistic, comparable to paid tools
- Card required for free tier: No
Mobile-specific features:
- Camera integration: tap to capture directly from phone camera
- AR mode: not available (renders from still photo instead)
- Offline use: no — requires internet connection
Verdict: The most accessible free mobile option. No download barrier, no card required, and multiple free renders of genuine quality.
Planner 5D (Native App — iOS & Android)
App Store rating: 4.5 stars (200,000+ ratings) Play Store rating: 4.3 stars (1M+ downloads)
Planner 5D's mobile app is polished and well-reviewed. The free tier lets you create floor plans, drag in furniture, and view in 3D. Where the paywall hits: the HD render mode and AI-powered design suggestions require a subscription ($9.99/month or $2.99/month annually).
Free tier test results:
- Floor plan creation: unlimited, fully free
- 3D visualization: available on free tier (lower quality)
- AI photo redesign: not available on any tier — Planner 5D doesn't do photo-based transformation
- Renders before paywall: unlimited for manual 3D views; AI features locked entirely
- Card required: No for free tier
Mobile-specific features:
- Camera integration: measure and scan room layouts with phone camera (premium)
- AR mode: "View in AR" available (limited on free tier)
- Touch interface: excellent — designed mobile-first
Verdict: Strong free app for layout planning. If you need AI photo redesign, look elsewhere.
Houzz (Native App — iOS & Android)
App Store rating: 4.7 stars (500,000+ ratings) Play Store rating: 4.3 stars (5M+ downloads)
Houzz is primarily an inspiration platform and professional marketplace. The app is free to download and browse. Its standout free feature is "View in My Room" — AR-based furniture placement using your phone camera. You can see how a sofa or lamp would actually look in your space before buying.
Free tier test results:
- AI photo redesign: not available
- Browse photos: unlimited, free
- AR furniture placement: free for products in the Houzz catalog
- Renders before paywall: N/A — no AI rendering feature
- Card required: No
Mobile-specific features:
- Camera integration: excellent AR mode
- Real-time AR furniture overlay: one of the best implementations available free
- Product purchase integration: tap to buy what you see in AR
Verdict: Best free AR furniture visualization. Not an AI room redesign tool, but unmatched for placing specific furniture pieces in your actual room.
IKEA Place (Native App — iOS & Android)
App Store rating: 4.2 stars Play Store rating: 3.9 stars
IKEA Place is entirely free and requires no account. You point your camera at a room and place true-to-scale IKEA furniture in your actual space using AR. The limitation is obvious: you can only place IKEA products. But if you're furnishing on a budget, IKEA's catalog is broad enough to make this genuinely useful.
Free tier test results:
- Cost: completely free, no paid tier exists
- Products available: full IKEA catalog
- AI redesign: not available — this is AR placement only
- Account required: no
- Card required: no
Mobile-specific features:
- AR furniture placement: excellent, true-to-scale
- Room measurement: basic spatial awareness
- Works offline: partially (downloads catalog data)
Verdict: The best free AR furniture app, period. Zero cost, zero friction. Limited to IKEA products.
Decormatters (Native App — iOS)
App Store rating: 4.6 stars (10,000+ ratings)
Decormatters has genuine AI design features on mobile, including a style quiz that generates room suggestions. The free tier is more restricted than it appears in marketing — you get a 7-day trial of premium features, then a reduced free tier.
Free tier test results:
- AI renders before paywall: 3–5 during trial, then 1–2/month after
- Output quality: good
- Card required: Yes, to start the trial
- After trial expires: very limited free tier
Mobile-specific features:
- Camera integration: yes
- Style quiz AI: free during trial
- iOS only: Android version has fewer features
Verdict: The free trial is useful for short-term projects. The permanent free tier is too restricted for ongoing use. Requires card upfront.
RoomGPT (Mobile Browser)
RoomGPT's mobile experience runs in-browser. The free tier is extremely limited — typically 3–5 renders total before a hard paywall. Exports include a watermark.
Free tier test results:
- Renders before paywall: 3–5 total
- Watermark: yes on free exports
- Account required: No for first render
- Card required: No for first renders, then yes
Verdict: Good for a quick first experiment but not a viable ongoing free tool.

Camera Tips for Better AI Results
If you're using a mobile app that takes a still photo as input (rather than live AR), the photo quality directly affects the AI output quality:
- Shoot during the day: natural light gives the AI more accurate color and shadow information
- Use landscape orientation: captures more wall surface, especially important for living rooms
- Include floor and at least one wall junction: helps the AI understand the room's geometry
- Step back as far as possible: wide shots produce better redesigns than tight close-ups
- Avoid mirrors in frame: the AI can get confused by reflective surfaces
- Clean up clutter first: a cluttered room gives AI less to work with for style transformation
The Download Decision
Whether you download a native app or use a web app comes down to two things: storage space and speed.
Native apps use storage (Planner 5D is ~200MB, Houzz is ~150MB) but often feel faster. Web apps like AI Smart Decor use no storage and require no update management but need a reliable internet connection.
For one-time or occasional home design work, a web app is almost always the better choice. For ongoing projects where you're building layouts over multiple sessions, a native app may be worth the install.
