# 九讯演示 vs 3D

The clearest difference is update cadence: 3D at every 2 months against 九讯演示's every 11 months. 九讯演示's advantage is iOS requirement (10.0 vs 14.3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

九讯演示 ships an update every 11 months, 3D every 2 months. The most recent releases landed on October 25, 2026 and October 27, 2026 respectively.
