# 得力e+ vs 知音楼

The clearest difference is ads: 知音楼 at none against 得力e+'s shown. 知音楼 also leads on monetization model (free vs ad-supported). 得力e+'s advantage is review sentiment (27% vs 0%). On price, update cadence, in-app purchases and device support there is nothing between them.

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

得力e+ ships an update every 4 weeks, 知音楼 fortnightly. Both last shipped on October 26, 2026.
