Fitch is a formal proof system recently gaining momentum in logic education due to its structural similarity to human reasoning. We introduce Fitch via its web-implementation at http://www.proofmood.com. Then we compare Fitch with more well-known proof systems such as Hilbert System, Natural Deduction and Sequent Calculus. Similarities and differencies among these systems are discussed.
