STR Quick-Reference App

The STR Quick-Reference App from Stand to Reason gathers concise text and video summaries on Christian apologetics, ambassadorship, worldviews, ethics, and related topics so you can answer with clarity and grace.^1

Stand to Reason trains Christians to think clearly about their faith and to make an even-handed, incisive, yet gracious defense for classical Christianity and classical Christian values.^1 Greg Koukl founded the ministry in 1993 and still serves as president. He has spoken on more than 90 university campuses, hosted a call-in radio show for over 30 years, and written seven books, including Tactics, The Story of Reality, and Street Smarts. He earned master's degrees in Philosophy of Religion and Ethics from Talbot School of Theology and in Christian Apologetics from Simon Greenleaf University, and he teaches as an adjunct professor in Christian apologetics at Biola University.^3

The app is free on iPhone, iPad, and Android, and a web library is available too.^1^5 Official pages highlight tactics, abortion, and other issues from a classical Christian perspective. The companion web library includes Mentoring Moments, Apologetics Tips, The Story of Reality, and Islam.^1
