A couple of weeks ago I took a few days to write a new WordPress plugin. There is a free service from LifeChurch.tv called Church Metrics. This service allows you to setup Campuses, Categories, and Events that you can track numbers for. These numbers can be anything you’d like. Attendance, baptisms, first-time visitors, etc.
Church Metrics Dashboard takes these numbers and can either display them as Dashboard Widgets in your WordPress Admin or provide you with a shortcode to display them anyplace on your site. It also offers some unique features not available from Church Metrics. Like the ability to combine multiple categories into a single count, percentage differences between comparisons, average counts, and year over year counts.
