SermonAudio
Free · sermonaudio.comSermonAudio is the widest sermon library you can carry. The official count is over 3 million free sermons from thousands of conservative churches and ministries. You can browse by speaker, series, topic, language, or Bible passage, and many churches stream their services live inside the app.
The Sermons app (version 3.2) covers the listening basics. You can download audio or video, change playback speed, sync your play history, and download auto-generated transcripts. A Church Finder map shows broadcasters near you, which helps if you are looking for a church and not only a sermon.
The lens is conservative Protestant only. Reformed, Presbyterian, and Baptist pulpits are common. You will not find Catholic, Orthodox, or mainline churches. Store ratings are mixed (4.1 on iPhone, 3.4 on Android), and some reviews describe sermons restarting mid-play. Apple's listing says it contains ads while Google Play says it does not, so check for yourself.
