# 结构大师HD vs 找规范

The clearest difference is ads: 结构大师HD at none against 找规范's shown. 结构大师HD also leads on iOS requirement (9.0 vs 12.0). 找规范's advantage is device support (3 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 结构大师HD sells 4 one-off in-app purchases and 找规范 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

结构大师HD ships an update every 2 months, 找规范 monthly. The most recent releases landed on October 6, 2026 and October 7, 2026 respectively.
