ICEBlock: The app that alerts users about immigration raids
Briefly

ICEBlock is a free mobile app launched by developer Joshua Aaron in April 2025 to alert users about the presence of Immigration and Customs Enforcement (ICE) agents. Motivated by concerns over immigration policies and historical parallels to authoritarian regimes, Aaron designed the app to provide a collaborative, anonymous platform for immigrant communities. Users can report the location of ICE activities with two taps, sending alerts to others nearby. The app is data-protective, not retaining personal information or geolocation, with reports deleted after four hours. It has acquired over 20,000 users, serving as a vital resource, particularly in cities with significant immigrant populations.
ICEBlock functions as an early warning and anonymous platform designed to help immigrant communities stay informed about operations carried out by the Immigration and Customs Enforcement (ICE). Users can mark the location of agents and send alerts within a five-mile radius.
Joshua Aaron explained that he created ICEBlock in response to the Trump administration's plan for mass deportations, citing historical parallels to authoritarian regimes.
The app operates under the motto 'See something, tap something', allowing users to report ICE presence through a simple two-tap process on their phone.
ICEBlock doesn't collect personal data or permanent geolocation, with reports auto-deleted after four hours to protect user anonymity.
