学习复习安排助手，根据艾宾浩斯遗忘曲线制定的学习类软件。 学习不复习，学习效率不高，遗忘率高，都是没有妥善安排好。但是，这款软件可以在你输入一个学习任务之后，在最适合的时候提醒你复习，实现记忆效果最大化。这也是根据遗忘曲线原理制定出来，适合人类记忆能力的实用软件。主要有下面功能： 1、添加学习任务，自动在每天提醒你哪些内容应该学习，哪些内容要复习。 2、添加单次任务，单次任务则每天提醒你自己制定的一次任务，不具备周期提醒，普遍适用于单次学习安排以及单次工作安排。 3、根据每个人的记忆能力不同，可个性化提供修正复习间隔，但是我们仍推荐您使用推荐的安排时间，此时间经过大量的教育学和心理学的实验验证，效果更好。 4、提供附件功能，利用手机复习更快捷。 5、提供番茄计时器功能，复习更专注，工作更有效。
