## What is 不忘词典?

查过的单词就忘记了？「不忘词典」能够让你彻底记住每一个查过的单词！

「不忘词典」提供词根词缀帮助你理解单词，利用遗忘曲线循环记忆来帮你记住单词。

记忆算法来自新东方《17天搞定GRE单词》一书，分别在5分钟、30分钟、12小时、一天、两天、四天、七天和十五天的时候提醒复习单词，非常有效。

由于讨厌市面上很多词典花里胡哨的设计，所以界面采用了比较有“禅意”的设计，一丝一毫多余的信息都没有，就是查单词、记忆、记忆再记忆。

希望可以帮助和我一样生词很多、但查了一遍又一遍还是记不住的同学。

功能：
* iCloud 备份，多设备同步
* 通知提醒
* 词根词缀分析单词
* 单词真人发音
* 例句
