What Is Room Sketch 3D?
Room Sketch 3D is the most cross-platform of the one-time options. Web, iPhone, iPad, and Android — one purchase covers all. No in-app purchases, no premium tiers, no platform fragmentation.
350+ pre-measured furniture pieces, snap-to-grid drawing, 2D and 3D, AR scanning on iOS. The full app is unlocked at the one-time price.
Trade-offs: not free at the basic tier (Sweet Home 3D desktop is); rendering isn't as polished as Live Home 3D's Pro tier. The benefit: broadest platform support and lowest cross-platform cost.
How They Compare on What Matters
True one-time vs in-app purchases
Room Sketch 3D, Sweet Home 3D, and Live Home 3D are genuinely one-time. Home Design 3D's IAP model means total cost varies. The 'true one-time' label belongs to Room Sketch 3D, Sweet Home 3D, and Live Home 3D.
Cross-platform breadth
Room Sketch 3D: web + iOS + Android. Live Home 3D: Mac + iOS. Sweet Home 3D: desktop + paid mobile. For cross-platform single-purchase coverage, Room Sketch 3D is unmatched.
Total cost for cross-platform use
Room Sketch 3D: $9.99. Live Home 3D Pro for Mac + iOS: $79.98. Sweet Home 3D mobile + desktop free: $14.99. The cheapest cross-platform option is Sweet Home 3D if you tolerate the dated UI; the most polished is Room Sketch 3D.
Render quality
Live Home 3D Pro produces the best renders of the one-time options. Room Sketch 3D and Sweet Home 3D are realistic but more functional. Home Design 3D is in between.

Frequently Asked Questions
What's the cheapest floor planner with no subscription?
Sweet Home 3D's desktop version is free. For cross-platform with mobile, Home Design 3D ($6.99 + IAP) or Room Sketch 3D ($9.99) are the cheapest. Room Sketch 3D is the cheapest fully-cross-platform single purchase.
Are one-time floor planners as good as subscription tools?
For typical home planning, yes. Subscription tools push more frequent updates; one-time tools provide stable feature sets. The actual planning workflow is similar across both. Subscription tools win on photorealistic rendering depth.
Why do most floor planners charge subscriptions?
Subscription pricing produces predictable revenue. The trade-off for users is paying indefinitely for software they may use occasionally. One-time-purchase apps align cost to actual use.
Does Room Sketch 3D have hidden fees?
No. The one-time price unlocks every feature on every platform. No in-app purchases, no premium tiers, no recurring fees. The pricing is genuinely flat.
How much does Room Sketch 3D cost?
$9.99 one-time. Cross-platform: web, iPhone, iPad, Android. 30-day money-back guarantee.
