# 压缩专家 vs 灵光

The clearest difference is ads: 灵光 at none against 压缩专家's shown. 灵光 also leads on update cadence (every 10 days vs every 2 months) and review sentiment (76% vs 63%). On price, rating, ratings volume and in-app purchases there is nothing between them.

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

压缩专家 holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 76 and 84 respectively. Written reviews complicate that: 63% of 压缩专家's written reviews are positive against 76% of 灵光's, so the app with the better star average is not the one people write more warmly about.

压缩专家 ships an update every 2 months, 灵光 every 10 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
