The ease of use and the number of features. The app has all the information someone could need to keep track of their ministries. I like the reminders feature and the ability to have the app notify me if someone is not showing up. I wish there were more options for a calendar. I would like to be able to have the option to add a service to my calendar that I don't have services for. I would recommend this app to anyone who needs to keep track of their ministry. The ease of use makes it a great choice for any church. We have been able to make our services much more efficient and organized.
