Ever been in a conversation about faith and wished you had a clear, thoughtful answer at your fingertips? The STR Quick-Reference App from Stand to Reason puts concise summaries on Christian apologetics, ethics, worldviews, and ambassadorship tactics right in your pocket — through both text and video — so you can engage confidently and graciously wherever the conversation leads.^1
Founded by Greg Koukl in 1993, Stand to Reason has spent over three decades training Christians to think clearly about their faith and make an "even-handed, incisive, yet gracious defense for classical Christianity."^2 Greg holds dual master's degrees in Philosophy of Religion and Ethics (Talbot School of Theology) and Christian Apologetics (Simon Greenleaf University), has spoken on more than 90 university campuses, and has hosted his own call-in radio show for over 30 years.^3 In September 2025, Greg appeared on The Diary of a CEO — one of the world's most popular podcasts — debating atheist Alex O'Connor and psychiatrist Dr. K on meaning, purpose, and whether a changed life can serve as evidence for Christianity.^4 The app distills that depth of experience into a quick-reference format — covering topics from conversational tactics to the sanctity of life — and includes an audio Bible with a devotional reading plan. It's completely free, available in five languages, and also accessible via a web version.^1
Why Christians Love It"As a pin-wearing Stand to Reason geek, I'm very pleased to see they made this app. The information they provide on Tactics alone is worth the download. But they also provide excellent quick reference guide on abortion. AND, just for good measure, there's an audio Bible feature with devotional reading plan!"^5
"Soo brilliant. Audio bible all the time and references for great conversations with friends. Absolute essential for every Christian phone. And I'm a Catholic, so you know this app must be good if it's that far reaching in applicability."^6
"I am impressed by the clear English and clear reasoning on sticky problems. They are a voice of level headed reason and real understanding and listen."^6
