Features and specs

What each product offers, as listed by its team.

Display Info 5 features
Cert Decoder 4 features
  • Clean Material You Design
    The app follows Google's Material You (Material Design 3) guidelines with dynamic theming, providing a modern and visually appealing interface that adapts to the user's wallpaper colors on supported devices.
  • Comprehensive Display Information
    DisplayInfo provides detailed and extensive information about the device's display, including resolution, density, refresh rate, HDR capabilities, color gamut, and more — all consolidated in one easy-to-access application.
  • No Permissions Required
    The app gathers display information using standard Android APIs without requiring excessive or invasive permissions, making it privacy-friendly and safe to use.
  • Open Source
    Being hosted on GitHub as an open-source project, users can inspect the source code for transparency, contribute improvements, and verify that no malicious behavior exists within the app.
  • Lightweight and Focused
    The app is purpose-built to do one thing well — display device screen information. It doesn't bloat itself with unnecessary features, ads, or unrelated functionality, keeping it simple and efficient.

Possible disadvantages

  • Limited Feature Set
    The app is narrowly focused on display information only. Users looking for a broader device information tool (battery, CPU, sensors, etc.) will need additional apps to complement it.
  • Small Community and Limited Updates
    As a relatively niche open-source project, it has a small contributor base, which may result in slower updates, bug fixes, and feature additions compared to more popular alternatives.
  • No Export or Sharing Functionality
    The app does not appear to offer built-in options to export or share display information as a text file or report, which would be useful for troubleshooting or comparison purposes.
  • Limited Device Compatibility Testing
    Being a small project, it may not be extensively tested across a wide range of Android devices and OS versions, potentially leading to inaccurate readings or UI issues on certain hardware.
  • Lack of Detailed Documentation
    The GitHub repository provides minimal documentation beyond basic descriptions, making it harder for new contributors to understand the codebase or for users to fully understand what each displayed metric means.
  • User-Friendly Interface
    Cert Decoder is designed with a simple and intuitive interface that makes it easy for users to navigate and use the tool without requiring extensive technical knowledge.
  • Comprehensive Analysis
    The tool provides detailed analyses of certificates, including information about validity, issuer, encryption algorithms, and more, helping users understand their security certificates thoroughly.
  • Free to Use
    Cert Decoder offers its services free of charge, making it accessible for individuals and organizations without budget constraints.
  • Quick Processing
    The tool processes certificate information rapidly, providing almost instant results for users, which is crucial for time-sensitive tasks.

Possible disadvantages

  • Limited Advanced Features
    Compared to some paid alternatives, Cert Decoder might lack advanced features that are necessary for more complex certificate management and diagnostics.
  • Reliance on Internet Access
    Users need an active internet connection to utilize the tool, which can be a limitation in areas with unreliable internet service.
  • Privacy Concerns
    While using an online service to decode certificates, there can always be privacy concerns regarding sensitive data being uploaded to a third-party server.
  • No Offline Mode
    Cert Decoder does not offer an offline mode, which could be a drawback for users who require functionality without constant internet availability.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
