Purr APK: Rootless Screen Resolution and DPI Changer for Android

Purr APK is an open-source Android application designed to change screen resolution and DPI settings without requiring root access. Developed by tytydraco, Purr uses advanced Android APIs and optional ADB permissions to give users control over display appearance and optimization. The app stands out with a clean interface, robust compatibility checks, and privacy-conscious development. Purr helps Android users fine-tune their device display for performance, battery life, or gaming needs.

What is Purr? – Purpose and Core Functionality

Purr serves users who want to adjust their device's screen resolution or DPI on Android. Most built-in options in Android only allow minor changes. Purr goes further, letting users select custom resolutions or DPI values for precise adjustment. This flexibility benefits users who want better game compatibility, performance, or battery efficiency. The developer, tytydraco, released Purr as open-source software, allowing for community audit and improvement. Unlike many tools, Purr does not require root; instead, it uses Android Debug Bridge (ADB) permissions. Root is optional for advanced users. By employing hidden APIs, Purr lets users change display settings that would otherwise be locked.

Purr is different from standard Android display tools because it offers full customization, compatibility checks, and a streamlined experience. Many third-party apps require root, lack safety features, or do not let users revert changes easily. Purr fills these gaps with a practical, minimalist approach.

Key Features of Purr – Full Feature Breakdown

Rootless Resolution & DPI Adjustment

Purr’s primary feature is its ability to modify both screen resolution and DPI without root. Users only need to grant a one-time permission using ADB. After that, changes can be made directly inside the app. Root access is not required for any function, but it remains an option for advanced users. Purr works on a range of Android devices, starting from Android 6.0 and newer.

Advanced DPI Scaling & Customization

Purr enables advanced DPI adjustments based on pixel diagonals and custom calculations. Users can pick from preset options or input their values for precise control. Before applying new settings, Purr checks for compatibility and warns if the user’s choice could cause display issues. This helps prevent display problems while offering flexibility for different devices and preferences.

Performance & Battery Optimization Benefits

Adjusting resolution or DPI can affect device resource use. Lower resolutions reduce GPU workload, enhance battery life, and provide smoother performance in demanding games. Some users also lower screen density to minimize power use during routine tasks. Purr’s flexible settings let users experiment for their own balance between visual quality and efficiency.

UI/UX Experience and Usability

Purr’s design focuses on clarity and simple navigation. The app uses a minimalist interface with functional menus and direct options. Users are greeted by a cat mascot, adding a light, playful element. Key features are organized logically, making it easy for users with technical backgrounds to find needed functions without clutter or distraction.

Open-Source Transparency and Community Support

Purr is open-source, with its code published on GitHub. Users, developers, or privacy advocates can review code for integrity. This transparency gives users confidence in data handling and app behavior. Community contributions and feedback improve the app. There are no ads, tracking, or data collection. Support is available via email or Telegram.

How Purr Works – Step-by-Step User Guide

Granting Permissions and Initial Setup

To use Purr, users enable developer options on their Android device and grant ADB permissions once. After this step is completed, Purr can apply changes without running in the background. Advanced users may choose the root option, but it is not required for the app’s main features.

Using Purr to Change Display Settings

Users open Purr, where the mascot greets them. They select a preset or input a custom resolution or DPI value. Purr checks if the chosen configuration fits device capabilities. Once applied, some changes may prompt a device reboot for full effect. Safety mechanisms are in place to alert about risky settings.

Restoring Default Display Settings

If needed, Purr allows users to revert to the original screen resolution and DPI. Built-in compatibility checks protect against unintentional changes. Users can experiment, knowing changes can be undone.
