A church app is a mobile application designed to help members of a church community stay connected, informed and engaged with their church. It allows church leaders to easily communicate important updates, events, sermons and other resources to their congregation. The app can be customized to meet the specific needs of a particular church and may include features such as prayer requests, Bible study tools, devotionals, online giving, social networking and more.

With a church app, users can access live and recorded sermons, view the church's calendar of events, register for events and classes, give donations, connect with small groups or ministries, and communicate with church leaders and fellow members. The app can also provide push notifications to alert users of upcoming events, prayer requests or important announcements.
