Purr — Rootless Resolution Cha

Purr is an all-in-one resolution changer app for Android devices that does not require rooting. It uses Android SDK reflection to access hidden APIs and change the resolution of the phone's screen. The app requires a special permission that can be granted using ADB. Changing the resolution of the display can have benefits such as reducing the load on the GPU and improving compatibility with certain games. Purr calculates the DPI using mathematical calculations and verifies resolutions for compatibility before applying them. Custom resolutions can also be specified in the app's settings menu. Additionally, the app features a cute cat animation when opened.

The advantages of using Purr software are as follows:

- No root required: Purr allows users to change the resolution of their Android devices without the need for rooting, making it more accessible for a wider range of users.

- Reduced GPU load: By reducing the resolution of the display, Purr can help decrease the load on the device's GPU, potentially improving performance and battery life.

- Better compatibility for games: Some games may be designed for standard -9 displays rather than widescreen displays. Changing the resolution to a more suitable aspect ratio can enhance the gaming experience.

- Accurate DPI calculation: Purr uses complex math calculations to accurately determine the DPI (dots per inch) for new resolutions. This eliminates the need to manually calculate the resolution's diagonal inches, making the process easier and more precise.

- Compatibility verification: Purr verifies resolutions for compatibility before applying them, acting as a failsafe to ensure that only compatible resolutions are used.

- Custom resolutions: Users have the option to specify custom resolutions according to their preferences, providing more flexibility in adjusting their device's display. Additionally, the app features an adorable cat logo, adding a cute touch to the user experience.
