★★★☆☆

pdf支持需要每月购买,实在太贵,也不方便。希望能支持手指滑动翻页,每次都去点太麻烦了,pdf书签希望有能有,笔和高亮笔,形状那几个图标独立出来。这个软件非常流畅,也是安卓端开创手写的软件之一,但是却渐渐跟不上发展了,作为一款效率软件,操作逻辑却不够直观,这是个大硬伤啊,而且搞个二级菜单,我不觉得这样会更好开发。

Great.非常好的手写类软件,与三星galaxy tab s6适配不错。无论是分类,备份,导入导出,都挺好。There are some problems.但是也有一些问题。比如压感过于敏感,导致写的字有时候忽大忽小。移动页面的时候,有马赛克。插入图片之后,再编辑图片很困难。希望以后能做得更好。By the way,chinese suits not well,and there is no OCR,but that is ok

升级了账户,可以在pdf上书写非常方便。但是希望能增加pdf的目录功能,使翻页更加顺畅。通常都是4,500页的文件,一页一页翻真的不方便! 书写感受很不错,背景可调整,完美适配三星tab s6。总体来说,是个不错的软件!

强烈建议增加文本再次编辑功能,现在的问题在于,选择文本模式后,只能编辑一次就不能再次编辑了,如果想再次编辑只能全部删除之后再重新编辑,比如想简单的调一下每行文字之间的差距都无法做到,希望可以更新这项功能,谢谢。 please add text editing mode , because you just can edit text one time,then the text was locked ,you can not edit it again ,so it is so redundant to users 。I hope you can roger that, thanks alot.
