CivilStack is an iPhone application developed by Joe Uelk in the Education & Reference category. This app offers immediate access to location-based political representation, enabling users to view congressional districts, party representation, and contact officials effortlessly. Users can search all congressional members, access detailed profiles including social media accounts and voting history, and visualize the impact of their vote on federal offices compared to other states.

Additionally, CivilStack allows users to quickly register their opinions with elected officials, share their district and voter registration status on social media, post officials' contact information, and cast approval or disapproval votes. With a focus on transparency and civic engagement, CivilStack aims to empower users in their interactions with political representatives.
