Citizen是一款在美国广泛使用的实时警报应用，目前已覆盖120个中大型城市，总下载量达2000万次，App Store评分为4.8分[1]。该应用通过整合官方应急部门无线电数据、《梅根法案》规定的性侵犯公开数据库以及用户上报信息，在地图上标记犯罪事件、灾害和可疑人员[1]。为激励用户参与，该应用向提供现场直播的用户提供最高400美元的现金奖励[1]。
除基础免费功能外，Citizen提供包含音视频联络安全专员、实时监控、高级警报和无线电直播的付费增值服务[1]。然而，这款应用的商业模式和运营方式引发了多重争议。创始人安德鲁·弗雷姆曾在洛杉矶大火期间未经授权悬赏3万美元追捕疑似纵火者，结果导致错误逮捕[1]。他还曾尝试推出VIP保镖上门服务，但遭当地警方反对后项目被冻结[1]。媒体批评指出，该应用将人类悲剧包装成娱乐产品，利用用户的恐惧心理和窥私欲[1]。此外，应用的技术也存在缺陷，其AI系统曾错误地将警方无线电中的"肚子痛"识别为"飞机坠毁"[1]。
Citizen, a real-time crime alert application operating across 120 major U.S. cities, has accumulated 20 million downloads and maintains a 4.8-star rating on the App Store [1]. The app aggregates data from official emergency dispatch radio systems, the sex offender registry established under the federal Megan's Law, and user-submitted reports to display crime incidents, disasters, and suspicious individuals on an interactive map [1].
The platform incentivizes user participation by offering cash rewards for on-scene live broadcasts, with payments reaching up to $400 for featured content [1]. Subscribers to the app's premium service gain access to features including direct contact with security specialists, real-time monitoring, enhanced alerts, and emergency radio feeds [1]. However, the application has drawn criticism for transforming human tragedy into entertainment content while simultaneously exploiting user anxiety and voyeurism, according to reporting by the New York Times [1].
Founder Andrew Frame has courted controversy on multiple occasions. During the Los Angeles wildfires, he posted a $30,000 bounty to apprehend a suspected arsonist without authorization, though the individual subsequently identified turned out to be innocent [1]. The company also attempted to launch a premium armed security service that would dispatch bodyguards to users' homes, but the initiative was frozen following opposition from local law enforcement [1]. Technical reliability issues have further undermined the app's credibility, with instances of the artificial intelligence misinterpreting police radio transmissions—notably transcribing reports of stomach pain as an airplane crash [1].
