App Notification Edge Lighting by Kraph Tech provides Android users with extensive customization options for their device's notification LED system. The app occupies a niche market position, focusing on users who prefer visual notification cues over auditory alerts and seek deeper personalization than standard Android settings allow. Its 3.73-star rating suggests moderate user satisfaction with room for improvement. The core functionality revolves around per-app notification customization, allowing users to assign unique LED colors, animation patterns, and timing durations for each application. The 'All Apps' feature comprehensively scans both user-installed and system applications, enabling customization even for built-in system notifications. Users can control LED animation duration through adjustable timing settings, providing flexibility for different notification priorities and visual preferences. User experience centers around a straightforward interface that organizes apps into scrollable lists with toggle switches for activation. The color picker and shape selection tools operate with standard Android design patterns, though the absence of preset color palettes requires manual RGB value selection. Real-world usage patterns indicate most users employ the app for distinguishing priority applications through color coding or creating visual notification hierarchies during meetings or nighttime hours. With no specific user reviews available, the application's moderate rating suggests mixed experiences that may include compatibility issues with certain device models or Android versions. The lack of detailed feedback makes it challenging to identify specific pain points, though the rating indicates some users encounter functional limitations or stability concerns. The application's primary strength lies in its granular per-app customization capabilities, though the absence of advanced features like screen-edge lighting or always-on display integration limits its appeal compared to more comprehensive notification systems. It serves best as a basic LED customization tool for users with specific color-coding needs or those using older Android devices with physical notification LEDs.
