# Keyplan 3D Lite vs SecondFloor

The clearest difference is monetization model: Keyplan 3D Lite at free with in-app purchases against SecondFloor's subscription. Keyplan 3D Lite also leads on ratings volume (53K vs 16) and rating (4.5 vs 4.3). SecondFloor's advantage is update cadence (fortnightly vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Keyplan 3D Lite sells 11 one-off in-app purchases and SecondFloor sells 4 in-app purchases, starting at $24.99 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 4.3. That said, the two scores are not equally well evidenced: Keyplan 3D Lite has 53K ratings behind it against 16, 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 60% of SecondFloor's.

Keyplan 3D Lite ships an update every 3 months, SecondFloor fortnightly. The most recent releases landed on September 24, 2026 and July 8, 2026 respectively.
