The developer behind Eyes Up, one of the many Immigration and Customs Enforcement-related apps removed by Apple in recent days, was busy on Wednesday evening at a local planning session for the nationwide “No Kings” protest, scheduled for later this month. When WIRED eventually reached him by phone, he asked to be only identified by his first name, Mark, for safety reasons. “The administration will act on their grudges,” he says. “And they are not afraid to do so, frequently.” He should know. Mark’s app, a platform built to serve as a repository for videos and other materials documenting ICE activity, is not alone in getting kicked off Apple’s App Store. Earlier in October, ICEBlock was among the first ICE-related apps Apple removed. The decision followed claims from US attorney general Pam Bondi that such tools endanger ICE officers. Apple has also removed other tracking apps—including Red Dot and DEICER—as well as Eyes Up. Like Mark, ICEBlock’s developer, Joshua Aaron, is determined to reverse the app store bans. “While I cannot speak to specifics right now, I can tell you that ICEBlock has an incredible legal team behind it and we are going to do everything in our power to fight this,” Aaron tells WIRED. Apple did not respond to WIRED’s requests for comment. Regarding Eyes Up, Mark says he has already appealed Apple’s decision to delist the app, twice.“I will appeal every single time they reject me, until it's back in the App Store,” he says. “Because it's pure cowardice, what they're doing. I'm not gonna let off the gas with Apple.” The ban ignited a fire under Mark, who’s performing more community outreach to let people know about Eyes Up and encouraging them to upload publicly documented encounters with ICE agents to the app, which is still currently available on the Google Play store and the Eyes Up website.
