# KIRI Engine vs Dot3D

The clearest difference is review sentiment: Dot3D at 82% against KIRI Engine's 62%. Dot3D also leads on rating (4.7 vs 4.4). KIRI Engine's advantage is ratings volume (1.3K vs 104). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. KIRI Engine sells 10 in-app purchases, starting at $9.99 per month and Dot3D sells 2 in-app purchases, starting at $49.99 per month. Whichever you choose, the download price is not the number that matters.

Dot3D holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: KIRI Engine has 1.3K ratings behind it against 104, so its average is the more settled of the two. Written reviews point the same way: 62% of KIRI Engine's written reviews are positive against 82% of Dot3D's.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 7, 2026.
