### 5/5 — Beautiful!!!

*2025-05-02*

The only thing that needs improvement is switching from meters to centimeters when focusing close...

UPDATE: the developer now added this feature. Thank you so much! Perfect for my needs now.

**Developer response:** Hello! 😊 Thank you for sharing your feedback previously. We've improved the calculation accuracy—results now display with 2 decimal places for greater precision.

### 5/5 — 增加厘米都支持好吗？跪谢

*2023-11-04*

增加厘米都支持好吗？跪谢.真的很重要

### 1/5 — Basically unusable

*2023-03-30*

The UI is broken and all the values are stuck together.

### 3/5 — 为什么半幅要比全幅的超焦距范围要少?

*2023-01-21*

应该是感光度尺寸越小，它的清晰范围是越大的，你这怎么是反着来的呢？

**Developer response:** 先说结论：传感器越小，超焦距范围越小。景深范围内（近景深和远景深）之间都是“清晰”的，那什么是“清晰”呢？清晰是指将照片放大到某个尺寸（标准是10英寸），人站在某个距离观看照片，无法分辨一个实点和一个模糊的圆。传感器越小，放大后的放大倍率越高，越容易看到模糊的圆，所以对精度要求越高，景深范围就越小。
