This app doesn’t work it’s a ripoff.

Response from developer

Hello, what error are you having?

Brackets and one other question

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?

Response from developer

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

Unhelpful

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

Response from developer

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!

Great, but crashes a lot

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
