User Reviews

Summary: Users largely rate the app as useful for revealing background activity and hidden apps and for general device monitoring, with several praising its ability to expose security issues. However, the majority of criticisms center on (a) lack of CPU usage or process monitoring and confusion between CPU/RAM data, (b) intrusive permissions and privacy concerns including perceived data collection/ads, (c) stability and compatibility problems on Android 14/One UI and some devices, and (d) perceived redundancy or poor UX. The overall sentiment is mixed: helpful in theory, but plagued by privacy, permissions, and compatibility issues.

Pros

Reveals background activity and hidden apps, aiding security awareness.
Provides useful device information and monitoring data.
Generally easy to use and yields positive results.
Found hidden apps and improved device performance on some devices.
Helps users notice suspicious activity (e.g., Netlink) and alerts.

Cons

No CPU usage or process monitoring; app seems to show RAM or general data instead.
Forced permissions and privacy concerns; broad data access and perceived data collection/ads.
Compatibility/stability issues on Android 14/OneUI 6.0 and on certain devices (e.g., Nvidia Shield); bugs.
Perceived lack of value or redundancy; some users label it as malware/ads.
User experience friction: frequent prompts and navigation difficulties.
