Truth Tables

The sole purpose of this program is generating, and displaying, truth tables.

This free version supports all usual connectives of classical logic, that is negation, conjunction, (inclusive) disjunction, conditonal (material implication), and biconditional (material equivalence), as well as the constants 1 and 0 denoting truth and falsehood, respectively. A cool thing is that, besides the somewhat boring standard notation of logic, you may use Lukasiewicz's stream-lined, shiny Polish notation, too.

And it doesn't stop here. If you are the down-to-earth, common-sense kind of person, you will find it reassuring that, by default, the program uses classical, two-valued, logic. But if you are more of the adventurous type, never stopping short of an enterprise, you will be delighted to learn that Truth Tables for Android supports a number of non-classical, multi-valued systems of logic, too. Never enter a river twice, and two negatives don't make an affirmation, so to speak!

Whats new

* NAND and NOR are more prominent for most screen sizes (requested by a user)
* cleaning up layouts (please report any problem with exotic devices)
* allowing "*" and "+" for conjunction and disjunction, respectively (requested by a user)
* optionally showing separator lines between main columns (requested by a user)
* on-screen keyboard optionally showing the propositional letters A, B, C,... instead of P, Q, R,... (requested by a user)

Very Useful This is a very good app for my math class. The only thing I can't get to work on my Galaxy S5 are the NOR and NAND functions. When I do the long hold on OR or AND, nothing happens.

Totally awesome

Isn't allowing keyboard The app isn't allowing me to manually type in operators. Tried switching keyboards but still nothing. (SwiftKey to stock, then back)

Nice free app I am using this on my Google Nexus 10 and it works very well. A very nice and simple app.

Smh This app is bullshit every time I enter the expression AB V ab' it wouldn't answer it

Got it... Very easy 2use....n solving

good job ;) limits the number of propositions?

Awesome This is, wait for it......legendary! Thank you, you guys for making this

You are the best kind of person. Free, no ads, no unneeded permissions, useful and easy. I can tell this is a labor of love. Rock on!

If you like sentential logic, you'll find this app to be useful and fun.

Awesome!

Just plain fun, and dev fixed FC literally hours (<12) after I emailed him. Such attention alone is worth 5 stars.

Awesome help towards my college mathematics.. 5stars

Does what is says on the tin This app works rather clearly for generating truth-tables. As a tutor of introductory logic, I intend to recommend to to my students.

Mgoniri I found what I was looking for.
