Description
You thought logic would be easier than math. Now you're doing derivations and it's too late to drop the course. This app is for you.
- Checks the syntax of symbolic sentences.
- Tests whether the derivation is complete.
- Derivable lines are coloured blue; hypotheses are coloured green.
- Provides an annotation of the derivation, showing line justifications.
- Annotated derivations can be emailed as RTF files.

Ratings and Reviews
Absolutely Useless
I bought this thinking maybe the other reviewers just couldn’t figure out how to work it or it had been updated since their reviews... NO. GARBAGE. And even once I thought I was getting the answers I needed, those turned out to be completely wrong. This is the biggest waste of time and money on this marketplace. Just use Chegg or Google it if you need homework answers.
The App does Work as a proof checker
This app does work. It can tell you if your argument proofs have errors or when they are free from errors. That is all it is there for.
This app does not TEACH you how the inference rules work and this app does not walk you through a proof. You must already KNOW what you are doing and you are checking to see if your proof works. This is fine for someone with lots of experience and wants confirmation that a particular proof works out.
Can this app be improved? YES, all they need to do is constantly update the features. We know the checking capabilities work. You can enter proofs done from a textbook and the checker will show the layout and validity of the proof. All they need now is some modules that explain and teach concepts. Explain and introduce concepts and walkthrough some proofs so users can see the concepts applied would make an awesome app. As is this only checks proofs only and you need to understand that before you purchase.
Not what it sounds like
I thought this was supposed to teach logic, which is what the title of the app indicates: “Logic 101.” What it actually does, I have no idea. Useless. Stealing money is what it does. More pawns of predatory, nihilistic capitalism. Congratulations.
