TaskManager is a real system monitor for your phone.
It shows you live graphs for your CPU, RAM, GPU, and network usage, and lets you see every single app and background process currently running.
What It Can Do:
Check the details: See exact RAM usage, process priority, threads, and start times.
Kill the junk: Force-stop misbehaving apps or stubborn processes instantly.
Pin important stuff: Keep key processes at the top of the list so they are easy to find.
Filter and search: Sort through everything quickly instead of scrolling endlessly.
Track your battery: Trace current power draw and charge current, and view actual health stats, voltage, temperature, charge cycles, and time remaining.
Monitor networks: Watch live upload and download speeds for Wi-Fi, mobile data, VPNs, and tethering.
If you want to dig deeper, you can check your SoC details, CPU cluster frequencies, GPU support for OpenGL and Vulkan, system uptime, swap usage, and CPU governors.
It also looks good while doing it. It uses Material Design with multiple themes, dynamic colors, and dark/light modes.
