没有log也没法打开宽容度功能，测点之后ev标尺不会显示测点的标记啊，都看不到测点的标记，要调整都没法调啊

**Developer response:** 你好，很抱歉对您的使用产生影响，目前已知是部分ios版本产生的bug ，下个版本会着重修复这个bug，目前可以尝试更新到最新的ios版本解决。

### 4/5 — 用是蛮好用的，但我会闪退

*2026-07-31*

别的都正常，分区测光一点开就闪退。没购买之前是不会闪退的，购买之后就闪退了，是什么原因能解决吗？

**Developer response:** 你好，很抱歉对您的使用造成了影响现在已经在1.7.0版本修复了这个问题

### 4/5 — 无法升级pro内容

*2026-06-03*

功能全面，胶卷相机需要用到的功能都有，分区测光功能太香了。
bug1：尝试升级pro版本却一直无法跳转。

另外期待能增加拍立得和宝丽来相纸的倒异率。
