NewPipe is a brilliant, privacy-focused Android app that lets you watch and download YouTube content without any Google services. Like ytt---dlp, its code is completely transparent. It doesn't use the official YouTube API, meaning no Google account is needed and your history isn't tracked.

By the way, this mp3 converter for youtube app itself is completely free and has zero advertisements. And it doesn't require invasive permissions like many other downloader apps.

Step 1: You can download it from F-Droid, the trusted repository for free and open-source Android software, which verifies the integrity and safety of all its apps.

Step 2: Search for a video within the app. 

Step 3: Tap the download button and select "Audio" and then MP3.
