# 阅界 vs CHM+

The clearest difference is ads: 阅界 at none against CHM+'s shown. 阅界 also leads on update cadence (every 2 weeks vs every 6 weeks). CHM+'s advantage is review sentiment (83% vs 53%) and monetization model (free with in-app purchases vs paid). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 阅界 sells 3 in-app purchases, starting at $1.99 per month and CHM+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

阅界 ships an update every 2 weeks, CHM+ every 6 weeks. The most recent releases landed on September 14, 2026 and September 26, 2026 respectively.
