# SQL教程 vs 3dmax教程

The clearest difference is ads: 3dmax教程 at none against SQL教程's shown. 3dmax教程 also leads on iOS requirement (10.3 vs 12.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. SQL教程 sells 1 one-off in-app purchase and 3dmax教程 sells 1 in-app purchase, starting at $0.99 per year. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on September 30, 2026 and October 1, 2026 respectively.
