Popup Ad Detector is an Android utility tool developed by APPDEV QUEBEC. It assists users in identifying the source of pop-up ads and uncovering hidden apps on their devices. By enabling the "Start monitoring apps" feature, users can track the app responsible for displaying pop-up ads. Additionally, the app offers a widget that displays the origin of pop-up ads, allowing for easy identification and removal of the offending app.

Hidden apps detection is another key feature of this tool, scanning all installed apps to unveil any suspicious hidden applications. Notably, Popup Ad Detector does not function as an ad remover, ad blocker, or antivirus software, ensuring clarity on its capabilities and limitations.
