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);

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\".

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.

Hi, for some devices CPU/GPU names are available, on some not. I am constantly working on adding more devices to my database. Thank you for your feedback.

Beautiful, dynamically themed app with a really easy layout. The premium version is definitely worth it for more in depth details and always good to support developers. Is there a reason storage would report as "not protected". System shows storage is encrypted on a stock locked device. App crashes when clicking DRM info.

Found and love skit. Decided to check out Devs other apps. All look amazing so buying them all. One suggestion is the put the type of all in the name. I use exif editors, phone info and app managers all the time, but will never remember the names of these apps. So would be nice to have the name also include phone info or exif editor and app manager to they're easier to search for on the phone.
