# PDF Reader vs 阅界

The clearest difference is review sentiment: PDF Reader at 71% against 阅界's 53%. PDF Reader also leads on monetization model (free with in-app purchases vs paid) and iOS requirement (12.0 vs 15.6). 阅界's advantage is update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Reader sells 5 one-off in-app purchases and 阅界 sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

PDF Reader ships an update every 3 weeks, 阅界 weekly. The most recent releases landed on October 8, 2026 and October 1, 2026 respectively.
