Abstract
Home Planner AI lets users scan a room into a 3D floor plan and restyle it with AI, but reviewers say basic tools that used to be free — like exact wall measurement — keep moving behind the Pro paywall over time.
Background
Home Planner AI: Room Interior scans a room into a floor plan and lets users furnish and restyle it with AI.
What it does
Scans a room to build a floor plan, then furnishes and restyles it in 3D with AI-suggested items from a large real-brand catalog.
What changed
Over time, basic functions that were previously free — exact wall-length measurement, common furniture items — moved behind the Pro subscription, and the app now updates 2-3 times a week, frequently resetting user favorites/settings.
Why it is soft
Reviewers say the underlying tool is genuinely good and years of loyal daily users exist — the complaint is specifically that things freely available before now require payment.
Strengths
The free tier's core floor-planning and room-visualization loop is still repeatedly called "the best design app" and "amazing even free," and enough users stick around despite the paywall creep to sustain 34M+ installs — real proof the free-first experience built genuine habit.
Market gap
The recurring complaints, most-common first:
Free features moved behind Pro
The most common and most emotionally charged complaint — features like exact measurements and common furniture that used to be free now require Pro.
Frequent, buggy updates
2-3 releases a week causing lost favorites, freezing, and lag as more AI features are layered in.
Billing issues
Unauthorized or unexplained charges, and difficulty getting refunds.
AI restyle quality
The AI "decorate this space" feature is described as worse than free general-purpose AI chat tools.
I have noticed that the app is getting especially greedy recently with what they give you for free. even simple fans or laundry baskets are now pro only.
items id the catalog saying that they are free but when placed into a room it says they are only avaliable for the pro version, and a lot of previously free items are now only on the pro version
- Draw a permanent line around a generous free tier. Basic measurements and common furniture categories, and never move items across that line later.
- Slow the update cadence with a favorites/settings migration test. Reviewers repeatedly cite update frequency itself as the cause of new bugs.
- Keep AI restyling as a value-add, not a gate. Basic measurement shouldn't be what AI features are used to paywall.
Build complexity
Estimated for one developer, part-time, no funding, no paid acquisition — a focused floor-planner and basic furnishing tool, not the incumbent's full 400,000-item catalog.
| Workstream | Weeks |
|---|---|
| Room scan + floor plan generator (walls/doors/windows) | 2.5 |
| 3D furnishing + basic catalog | 2.0 |
| AI restyle integration (off-the-shelf image model) | 1.5 |
| Free-tier-forever billing + polish | 1.0 |
| Total | 7.0 |
Expected revenue
Assumes a free floor planner forever, plus an $11.99/month Pro tier for exact measurements, HD renders, and the expanded catalog.
| Month 12, monthly | ||
|---|---|---|
| Installs | 10,000 | |

| Still on at 30d | 2,400 | 24% |
| Paid | 380 | 4% |
| Revenue | $4,500 |
Biggest challenges
The incumbent's real-brand furniture catalog — 400,000+ items across 30,000+ brands with store-accurate dimensions — took years of retailer partnerships to build; a solo builder can ship a great free floor-planner and basic 3D view, but can't realistically replicate that catalog alone, so the honest wedge is measurement and planning, not full furnishing.
AI angle
AI room-restyling (swapping materials/styles from a photo) is now cheap to build with an off-the-shelf image-generation API, genuinely faster than a proprietary rendering pipeline — but reviewers already say the incumbent's own AI restyle underperforms free general AI tools, so this is achievable, not a moat.
Conclusion
Build it. A large, well-documented paywall-creep complaint, tempered by the incumbent's real catalog moat that limits a solo builder to the planning tools, not the full furnishing experience.
