iCalvinus is the official system of the Presbyterian Church of Brazil and currently consists of 4 modules, namely iCalvinus, iCalvinus Synod, iCalvinus Presbytery and iCalvinus Igreja. Its main objective is to automate, and thereby speed up, the meetings of the Executive Committee and the Supreme Council of the IPB. Since 2010, when we started using it, the meetings are stored and available for consultation of documents, resolutions and minutes.

The iCalvinus application also has precious tools such as the Presbyterian Digest where it is possible to search for several IPB resolutions, the IPB Yearbook which provides registration data on Churches, Pastors, Councils and Organs, Bible, Hymnal and also the new features aiming even more agility during EC and SC meetings through direct communication with members and ease of attendance and voting processes throughout the meetings.

The totals and data presented in iCalvinus are based on data registered and obtained by SE-SC/IPB.
