# 简研 vs 语录卡片

The clearest difference is ads: 简研 at none against 语录卡片's shown. 简研 also leads on iOS requirement (10.0 vs 16). 语录卡片's advantage is update cadence (every 2 days vs every 5 weeks). On price, 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.

简研 ships an update every 5 weeks, 语录卡片 every 2 days. The most recent releases landed on October 9, 2026 and October 2, 2026 respectively.
