# Decompress Master vs 解压专家

The clearest difference is ads: 解压专家 at none against Decompress Master's shown. Decompress Master's advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Decompress Master sells 1 one-off in-app purchase and 解压专家 sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Decompress Master ships an update every 3 days, 解压专家 every 3 weeks. The most recent releases landed on June 12, 2026 and September 16, 2026 respectively.
