### 5/5 — 搜索速度确实最快，发展前景不错。

*2023-03-20*

1、现在一个人有好几个手机号码了，为了区分主要次要，我都是修改标签来识别，希望搜索结果显示自定义的标签，方便识别需要拨打的电话号码，该功能非常实用。

2、希望增加单手键盘，或者可以自定义键盘宽度，高度。

3、希望像系统拨号那样，保留“个人收藏”栏，最常用的联系人直接拨打。

4、希望增加双卡时，可选择用那个号码拨号，或发短信。

**Developer response:** 感谢您的反馈。
将会在下一版本为您提供号码标签功能。
个人收藏和自定义键盘已列入后续版本的开发计划。双卡拨打电话，iOS系统不允许第三方应用选择，所以这个功能没有办法为您开发。
最后，衷心感谢您的喜爱！

### 5/5 — 好评一下！

*2023-02-16*

启动无广告，使用中无广告。
希望保持下去，做一个无广告的拨号软件。
可以采取自愿打赏。
或者 设定一个月免费拨号次数。
