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);

The most important thing in the "Dashboard"

• Test your display state via "Screen tester";
• Check the noise around you with "Noise checker".

Even more features with "Premium"

Ratings and reviews

I tried several system info apps and finally settled on this one. It shows all the required information in a well-designed layout. Go premium and support Devs.

CPU usage will not open. Also, Data Export will not save any files. I tried selecting all 3 file shares and still it doesn't save any device logs.

I recently came across your elegant apps and sure enough I paid for all three. I'm really satisfied with all of them. Just a few minor requests regarding Castro app. 1) Hardware name with specifications: Kindly display key Hardware details. ex: Under CPU, along with CPU cores and specifications, kindly display the CPU manufacturer and model (Snapdragon 888, 2.96 ghz). This has wide ranging implications. Samsung releases both Exynos and Snapdragon variants, both differ immensely in performance.

What's new

Castro 4.6 is here and it comes with full Android 14 support (and new information coming with it), reference data in the "Noise checker", in-app language picker, better multi-camera detection, and much more!
