Important Legal and Policy Note:

 That's a very common question, as having videos offline can be extremely useful!

Before recommending specific apps, I need to provide an important caution:

> 🛑 Important Legal and Policy Note: Downloading videos from YouTube using third-party apps violates YouTube's Terms of Service (TOS). YouTube's TOS specifically prohibits accessing content through any technology or means other than the video playback pages themselves. Additionally, downloading copyrighted content without permission may infringe on copyright law in your region.

> The Official, Legal Way to Download:

> The only official, supported, and legal way to download most YouTube videos is by using the YouTube app itself and having a YouTube Premium subscription. This allows you to download videos for offline viewing within the YouTube app.

Popular Third-Party Apps Used for Downloading

If you choose to use a third-party application despite the risks mentioned above, here are some of the most frequently mentioned apps used by others, along with what they are best known for:

For Desktop (Windows/Mac)

 * 4K Video Downloader (or 4K Video Downloader Plus)

   * Pros: Highly popular, reliable, supports very high resolutions (4K, 8K), can download entire playlists and channels. It has a clean, straightforward interface.

   * Cons: The free version has limits on playlist downloads.

 * SnapDownloader

   * Pros: Supports over 900 websites beyond YouTube, offers fast download speeds, and supports multiple formats up to 8K.

   * Cons: It is primarily a paid application, though it may offer a trial.

 * ClipGrab

   * Pros: Free, open-source, easy-to-use, and includes a built-in search engine to find YouTube videos without leaving the app.

   * Cons: May have fewer advanced features compared to paid alternatives.

For Android Mobile (Often Sideloaded as APK)

Due to Google's policies against apps that violate YouTube's TOS, these apps are typically not found on the Google Play Store and must be downloaded as an APK file from their official websites (a process known as sideloading).

 * VidMate

   * Pros: Very popular with Android users, supports downloads from numerous video platforms, and is optimized for smartphones.

   * Cons: Since it's an APK, you must be careful to download it from a trustworthy source to avoid malware, and it may contain intrusive ads.

 * NewPipe

   * Pros: Open-source, respects privacy, and offers a no-ads environment for playing and downloading YouTube content without requiring Google Services.

   * Cons: Must be downloaded outside the official Play Store.

General Tips When Using Third-Party Downloaders

 * Be Careful of Installation: Since many of these apps are not in official app stores, they may sometimes be bundled with extra software or adware during installation. Read all installation prompts carefully.

 * Check Quality: Choose an app that allows you to select the video resolution (e.g., 720p, 1080p, 4K) and the desired file format (MP4 is common for video, MP3 for audio).

 * Use an Ad Blocker: Web-based downloaders are often riddled with pop-up ads and redirects, so a browser with a strong ad-blocking extension is recommended if you go that route.

Given the options, 4K Video Downloader is generally considered the most reliable and feature-rich desktop option by most users.
