很是喜欢，希望可以一直保持，希望可以优化一下日历界面，想要一个时间轴页面显示

### 5/5 — 四象限的方向是不是反了

重要且紧急应该是在右上角，象限的箭头默认朝右

### 5/5 — 软件很棒，抱歉之前给差评，一场误会

*2022-10-08*

我看到这个软件后面的标价是一元，我才说下载试试看，结果付款的一瞬间，卡里给我扣了19元，我就想问，谁给我解释一下？？？（以上是原评论。十分抱歉，后来自己查看了账单确实一起扣款了，是我误会了，还一时冲动给了差评，实在不好意思！这个软件用到现在还是很满意的！很简洁很方便。就是如果任务列表可以竖排列就好了，横排列有点不习惯，建议官方可以设置那种能自己选排版方式的那种就好了！整体很喜欢！再次抱歉！）

**Developer response:** 你好。一般是和其他App的定期扣款（比如视频会员）一起扣款了。请查看苹果账单：点击手机的 设置-点击最上方你的Apple ID-媒体与购买项目-显示账户-购买记录
