## Most critical reviews (4 lowest-rated)

### 1/5 — Does not work

*2025-12-08*

Nothing populates in the text box

### 1/5 — Doesn’t work

*2024-11-18*

Can’t enter values. I follow the instructions but nothing shows up when I try to enter data. The cursor moves but nothing shows. It appears that it just simply doesn’t work.

### 1/5 — It simply does not work.

*2021-10-02*

Text entered in the form does not appear.  Calculation summary is not shown.  This app is unusable.  I guess it back to excel.

### 3/5 — App not compatible with night shift/dark theme

*2022-06-27*

Cannot read test when dark theme is enabled and/or night shift kicks in. I was able to read text in entry boxes in the daytime.  After 8 pm when the night shift kicked in, could not read text.
