Castro is a huge collection of information about your device and a set of tools for monitoring its status. This allows you to check the performance of your device in real-time!

Large collection of the information
Castro processes and displays a huge amount of information, namely:

• Detailed processor statistics (CPU and GPU);
• Battery monitoring;
• Consumption of all kinds of memory;
• Data usage via Wi-Fi and mobile networks;
• Real-time sensors data with beautiful graphics;
• Detailed information about Cameras of the device;
• Full list of available audio and video codecs;
• And many other features, including DRM and Bluetooth!

The most important thing in the "Dashboard"
If you are not interested in too detailed information in a larger volume, you can always use the "Dashboard" window, which collects all the most important information - CPU usage, battery status, network usage, and memory load on the device.

Set of useful tools
Castro has in stock a large set of tools that help to test the status of the device, for example, "Data export", which allows you to save all the information in a file for later use or "Screen tester", which allows you to check the operability of the device’s screen.

Even more features with "Premium"
• Deep interface customization with various colors and themes;
• Network traffic speed monitor to track your connection speed;
• CPU usage monitor to keep abreast of frequency usage;
• PDF format for information exporting;
• And even more coming soon!
