## Most critical reviews (5 lowest-rated)

### 1/5 — This app doesn’t work it’s a ripoff don’t pay.

*2023-06-09*

This app doesn’t work it’s a ripoff.

**Developer response:** Hello, what error are you having?

### 1/5 — Unhelpful

*2020-03-05*

Only accepts one letter variable. No option to fill out table and calculate expression from the table

**Developer response:** One-letter variables are more convenient to enter and display, especially for large expressions. For example, (apple ∨ banana) is easily represented as (a ∨ b). This app builds a truth table from an expression, hence its name. If you wish for an interactive truth table to derive the resulting expression, we suggest our related app, Karnaugh & Algebraic Minimizer!

### 5/5 — Brackets and one other question

*2021-04-11*

Is there any reason I can’t use brackets? I’m trying to find the truth values under the main operator, but I’m not seeing any columns for specific operators. Where are they located?

**Developer response:** You may use brackets ( ).
Please contact us at info@kappsmart.com with the expression that you entered.

### 5/5 — Great, but crashes a lot

*2020-02-11*

When it works, it works great. After 2 hours into it, it would randomly crash or stop accepting inputs after !(

After the new version, the bug went away. 
Cheers

**Developer response:** Thank you for your review. The crash has now been fixed. Kindly update to the latest version!

### 5/5 — Great app!
