Android Pulse is a diagnostic tool distributed by Google since March, which has recently become visible to the public and is now on over 10 million devices. It operates without a user interface and monitors software for unusual system resource consumption. The app first appeared in March with seven builds before being listed in the Play Store. On Pixel devices, it is found in system settings, while on others, it appears as a blank square in the update queue. There was no formal announcement regarding its rollout. Europe has enacted regulations to enhance user control over devices, but essential system applications like Android Pulse are exempt from easy uninstallation. There is no evidence that Android Pulse poses a danger, but its late visibility raised user concerns.
