📝 About this app
这个程序是自家产品，无需任何权限，请放心使用。
从2013年初开始算，它一晃也跑了5年了。 5年内发生过很多事，最严重的是17年下半年，程序无法更新数据。因为雅虎停用数据接口，拿掉走势图。 没有数据和走势图，这程序就是个废物。 所以今天作者看到剩下的这些用户，想说，谢谢你们的不离不弃。
不过光说谢谢是木有用的，关键是让程序恢复功能。于是2017年底，作者花银子租了服务器，私心的加了广告，废寝忘食的编写数据程序， 自鸣得意的画了走势图，还自以为是的推出了新的用户界面，结果招来恶评如潮，真是欲哭无泪啊。难道作者的良心不会痛吗。
痛定思痛，作者根据用户反馈，推出了N个版本，多次修改界面，解决程序崩溃，终于在版本12.0+稳定下来。
都是故事了。 说点有用的，怎么用：
1）下拉更新
2）调整位置：按住货币条，向上或向下拉动，调整到你想要的位置。
3）其他功能：其他功能都看的到，就不累赘了。
Have fun.
