# KIRI Engine vs Pixel 3D

The clearest difference is rating: KIRI Engine at 4.4 against Pixel 3D's 3.9. KIRI Engine also leads on ratings volume (1.3K vs 16). Pixel 3D's advantage is review sentiment (73% vs 62%). 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 Pixel 3D sells 3 in-app purchases, starting at $8.49 per month. Whichever you choose, the download price is not the number that matters.

KIRI Engine holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: KIRI Engine has 1.3K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 62% of KIRI Engine's written reviews are positive against 73% of Pixel 3D's, so the app with the better star average is not the one people write more warmly about.

KIRI Engine ships an update every 3 weeks, Pixel 3D every 9 days. Both last shipped on November 3, 2026.
