Seal is an open-source Android app from developer junkfood that downloads video and audio from the platforms yt-dlp supports. It is free, carries no ads, and uses a Material You design. We host the unmodified APK, version 1.13.1 (F-Droid build), at 41.1 MB.
A yt-dlp front end with Material You styling
The defining fact is the engine underneath. Seal wraps yt-dlp, so its list of supported sites follows that tool rather than a fixed list inside the app. The interface uses Material Design 3 with a dynamic color theme.
The app first appeared on July 26, 2022, and the GPL-3.0-only source is on GitHub. It requires Android 5.0 or newer.
What a download session looks like
You paste a link and choose video or audio. For audio, Seal can embed metadata and the video thumbnail into the extracted file. For video, it can embed subtitles.
Playlists download with one click, and the embedded aria2c can act as the external downloader. Finished and queued items are managed inside the app.
People who want more control can run custom yt-dlp commands and save them as templates.
Seal against LibreTube, NewPipe and YTDLnis
The alternatives include LibreTube, NewPipe, YTDLnis, Litube, PlayTube and SkyTube. Several of these are viewing clients for video sites. Seal is built around downloading, with command templates and playlist handling at its core.
YTDLnis is also in the same category, so the choice between the two comes down to interface preference.
