Of course! "Youbookx" (also known as YouBook X or YouBookX) is a popular third-party app for YouTube that enhances the user experience with features not available in the official app. It's essentially a modded or modified version of the YouTube Android app.

Here’s a detailed breakdown of its parameters, features, and everything you need to know.
⚠️ Important Disclaimer Before You Start
Using third-party apps like YouBookX comes with significant risks:
- Account Ban Risk: Google can detect modified apps and may suspend or permanently ban your Google/YouTube account.
- Security Risk: These apps are not on the Google Play Store. You must download them from a third-party website, which could potentially host malware or malicious code.
- Privacy Risk: The app developer has access to all your YouTube activity, search history, and personal data.
- Instability: It may crash more frequently or have bugs that the official app doesn't.
Use at your own risk.
Main Features and Parameters of YouBookX
YouBookX focuses on giving users more control over their YouTube experience. Here are its key features, which can be considered its "parameters":

Ad Blocking
- What it is: Completely removes all ads from the YouTube app, including pre-roll ads, mid-roll ads, and banner ads.
- How it works: It uses a built-in ad-blocking mechanism that filters out ad requests before they are loaded.
Background Playback
- What it is: Allows you to play YouTube videos with the screen turned off or while using other apps. This is a feature often locked behind a YouTube Premium subscription.
- How it works: It bypasses YouTube's restrictions on playing audio-only when the screen is off.
Picture-in-Picture (PiP) Mode
- What it is: Lets you watch a video in a small, resizable window while you use other apps on your device.
- How it works: Similar to background playback, it enables the native Android PiP feature for YouTube, which the official app may restrict for non-premium users.
Enhanced Video and Audio Quality
- What it is: Offers more options for video resolution and frame rates than the official app. It also often includes an option to force higher audio quality (e.g., 256 kbps) or download audio in a separate format.
- Parameters:
- Video: You can often select resolutions up to 4K, 60fps, or even 120fps if the video supports it.
- Audio: Force high-bitrate audio streams.
Download Manager
- What it is: A built-in feature to download videos and audio directly to your device for offline viewing.
- Parameters:
- Download Video: Choose your desired resolution and format before downloading.
- Download Audio (MP3): Extract the audio from a video and save it as an MP3 file.
- Download Subtitles: Download subtitles in different languages.
Customization Options
- What it is: A settings menu to change the app's behavior and appearance.
- Parameters:
- Layout: Options to hide certain UI elements like the "Shorts" tab, "Up Next" suggestions, or the channel header.
- Themes: Some versions offer dark mode or other color themes.
- Default Playback Settings: Set your preferred video quality, autoplay settings, etc.
SponsorBlock Integration
- What it is: A community-driven feature that automatically skips sponsored segments, self-promotions, and other non-essential parts of videos.
- How it works: It uses a public database to identify and skip these segments, making for a much cleaner viewing experience.
Return YouTube Dislike (RYD)
- What it is: Shows the public dislike count on videos. After YouTube removed the public dislike counter, this feature uses a third-party API to retrieve and display the number.
- How it works: It fetches the dislike count from the
returnyoutubedislike.comAPI.
How to Install YouBookX (General Steps)
Since it's not on the Play Store, you need to "sideload" the APK file.
- Find a Trusted Source: Search online for "YouBookX APK download" or "ReVanced APK". Be extremely careful and choose a reputable website to avoid malware.
- Enable Unknown Sources: Go to your phone's Settings > Security > Unknown Sources (or similar wording) and enable it. This allows you to install apps from sources other than the Play Store.
- Download the APK: Download the YouBookX APK file to your device.
- Install the APK: Open the file from your notifications or downloads folder and tap "Install".
- Log In: Open the app and log in with your Google account. You may need to grant additional permissions.
Alternatives to YouBookX
If YouBookX seems too risky or stops working, consider these alternatives:
- ReVanced: This is the most popular and well-maintained alternative. It's a modded version of YouTube that is actively developed and generally considered safer. It has the same core features as YouBookX.
- NewPipe: An open-source YouTube client that is very lightweight and privacy-focused. It doesn't require a Google login and is available on the F-Droid store. It has a separate companion app (NewPipe) for downloading.
- YouTube Vanced: The original modded YouTube app. It is no longer being updated, but you can still find versions online. ReVanced is now its spiritual successor.
