About this app

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 useful graphs;
• Detailed information about device's cameras;
• Full list of available audio and video codecs;
• Monitoring temperatures of the device.

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.

More control with useful tools
• Share your device information using "Data export";
• Test your display state via "Screen tester";
• Check the noise around you with "Noise checker".

Even more features with "Premium"
• Deep interface customization with various colors and themes;
• Configurable home-screen widget, with information about battery, memory, and more;
• 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!

Really nice looking interface! But sometimes it's tricky to find certain pieces of info. However I only am giving it 2 stars because the 'long tap to copy' simply doesn't work and that is a very important feature. Also, perhaps consider reorganizing the categories on the main screen (especially the 'Memory' one; using that only for RAM and making a new category for storage memory). Also, the search function could use a lot of improvement.

Great and fantastic always works as it should with all the info this app requires, plus it was worth the extra few dollars to go PREMIUM. Awesome, keep it up:)

Nice app, but I'm getting a "missing files" error message when trying to view cpu usage. The phone is a Samsung S20, is there a fix?
