 Promise Tracker is a mobile data collection tool that allows citizens to track the status of government promises related to issues they care about. Citizens can create an issue-based data collection campaign and recruit other community members to join their monitoring efforts. As part of the Promise Tracker web tool, citizens can customize their own mobile data collection forms and deploy them on Android phones. To inform our design, we conducted several workshops in Brazil this year. One workshop was in São Paulo and another was in a favela in Belo Horizonte. During the workshops, participants identified issues they wanted to monitor in their community and discussed which of these issues the government was responsible for improving. Based on the chosen issues, we customized an Android data collection app and participants walked their community streets collecting data and discussing issues with their neighbors. Participants collected data on a number of topics they cared about including transportation, trash collection, accessibility, and housing demolition. Participants created data presentations from the data during the workshops. We also created interactive maps of the data they collected to host the photo and video stories they collected. Data collected and mapped using Promise Tracker can be used for a variety of civic scenarios such as lobbying the government for a specific infrastructure improvement or rallying one's community to fix a local problem. We are currently using the insights from our workshops in Brazil to inform the design of Promise Tracker which we will continue to prototype and test over the coming months.
