「班主任工作台」是写给班主任的纯本地班务工具。 点名、收回执、记加减分、写谈话、排值日、看课表、录成绩，都在这部手机上完成。没有账号，没有广告，也不会把班级数据传到云端。 我是这款应用的独立开发者。做它的时候只定了一条规矩：学生的姓名、电话、请假原因和谈话记录，只留在你自己的手机里。不是因为「隐私」听起来好看，是因为这些资料本来就不该成为某个产品的增长数据。我看不到你的班级，也没有云端副本可以替你恢复——这不是功能缺失，是边界。 打开「今日」，能看见这个班此刻的样子：实到和应到、谁请假、谁迟到、现在上到哪一节、还有哪些待办没做完。早自习点名、课堂随机抽人、下午收回执，都不用再另开一个表格。点学生的名字，就能改已交还是未交；未交名单可以复制出去。记错的加减分可以撤销。谈话、违纪和荣誉会写进这个学生自己的时间轴。 花名册和座位图在一起，点两名学生就能换座。请假登记后，会回到今日班况和当天的点名里。评语库、值日表、考试成绩、学生阶段报告，需要的时候再打开。数据可以导出成表格或加密备份，保存到哪里由你选。 有几句想提前说清楚。它目前就是一个班级、一部手机、一份加密数据。不能多人同时在线改同一本册子，也不会自动从学校平台拉取名单。语音输入只在你主动使用时调用，用来把待办说成文字；不用，就当它不存在。第一次打开会先请你阅读隐私政策，不同意就不会加载班级资料。 如果你正在带一个班，希望它能让你少翻几张表，把晚上那一点时间还给自己，也还给学生。 有问题可以写信：bytegeek@163.com
