CHRESTUS is a revolutionary tool for quickly investigating every argument for and against the historical existence of Jesus. As well as being a handy offline reference glossary, this app contains its own Bayesian calculator, for estimating your own probability that Jesus existed, using a basic model widely employed by scientists, governments, and corporations. Includes an expandable chronology graphic to visually see the references to Jesus and when they happened. And it gathers all known argument trees into one place, for and against, so for any question asked, you can find the answer, as far as it's known. Put together with the collaboration of Dr. Richard Carrier (author of On the Historicity of Jesus) in developing its structure and content, it will be continually updated to become and remain the most complete app for the purpose ever developed. Currently, it has no rival.
