# Keyplan 3D Lite vs AI Interior Design

The clearest difference is rating: Keyplan 3D Lite at 4.5 against AI Interior Design's 3.9. Keyplan 3D Lite also leads on review sentiment (64% vs 25%) and ratings volume (53K vs 36). AI Interior Design's advantage is update cadence (every 2 weeks vs every 3 months) and iOS requirement (13.3 vs 16). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Keyplan 3D Lite sells 10 one-off in-app purchases and AI Interior Design sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Keyplan 3D Lite holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Keyplan 3D Lite has 53K ratings behind it against 36, so its average is the more settled of the two. Written reviews point the same way: 64% of Keyplan 3D Lite's written reviews are positive against 25% of AI Interior Design's.

Keyplan 3D Lite ships an update every 3 months, AI Interior Design every 2 weeks. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
