投知卡 vs YNotes

投知卡把投资经典里的原则拆成一张张卡片，用间隔重复帮你把它们真正记住。 「纸与墨」的阅读界面 每张卡片是一页纸：衬线排印、克制的留白、没有花哨的动效。它想让你读进去，而不是刷下去。 按记忆规律安排复习 基于 SM-2 间隔重复算法安排每天该看哪几张。记住了的往后排，没把握的很快再来。 读不透的地方，看解读 每张卡片都可以展开一段解读，把原则落到具体情境上。 把一句话带走 喜欢的句子可以生成分享卡，五套纸片模板轮换。桌面小组件每天早上换一句。 关于内容 卡片内容整理自公开出版的投资著作，用于阅读与记忆训练。本应用不提供投资建议、不推荐任何证券，也不对任何投资结果作出承诺。投资有风险，决策请独立判断。
