UDL App

What if your Android phone could download any YouTube or OK video with a single tap — no ads, no limits?

UDL App by uniLoader is a completely free mobile video downloader built specifically for Android. It lets you save content from YouTube and Odnoklassniki (OK) directly to your device in MP4, MP3, or WEBM formats — regardless of video length or resolution. Think of it as a full-featured YouTube client replacement that adds a powerful offline saving engine. No subscriptions, no paywalls, just direct, one-click downloads.

Core Download Engine — What It Actually Does

UDL App works as a standalone media downloader and player. You can use it exactly like the standard YouTube app: search, browse, and watch videos. But the key difference is the integrated download button that appears on every video. Tap it, and you immediately see available formats, resolutions, and audio-only options. The app handles both combined audio-video streams and separate streams that YouTube stores on different servers. When audio and video are stored separately, UDL App performs on-device muxing — a process that merges the two files into one playable MP4. This muxing operation is resource-intensive and may increase battery drain, especially for large or high-resolution files. For short clips under a few minutes, the difference is negligible.

Supported Download Formats and Quality Tiers

• Video downloads: Full MP4 files with synchronized audio. Frame rates include standard (24–30 fps) and high (60 fps). Resolution options span from 360p up to 4320p (8K Ultra HD) — including 720p HD, 1080p Full HD, 1440p 2K, and 2160p 4K. All resolutions are available for any video length, provided the source supports them.
• Audio extraction: Convert YouTube videos to standalone MP3, M4A, or WEBM audio files. The app extracts the audio track at the maximum bitrate the source video offers — no artificial quality caps. This is ideal for building a local music library from streaming content.
• Batch and background downloads: Queue multiple downloads and let them run in the background while you browse other content. The download manager shows real-time progress, file size, and estimated completion time.

Turbo Mode — Ad-Free Experience with Performance Boost

UDL App runs without any intrusive advertisements. The Turbo mode (included by default) accelerates download speeds by optimizing the connection to YouTube and OK servers. It also reduces CPU load during muxing by using hardware-accelerated codecs when available. This means you get faster completions and lower battery consumption compared to standard mode. There are no limitations on download count, file size, or concurrent tasks.

Technical Considerations and Compatibility

The app supports Android 5.0 (Lollipop) and above. It handles videos of any duration — from 10-second shorts to multi-hour streams. The muxing process requires approximately 2–3 times the file size in free storage space temporarily. For example, a 1 GB video needs about 2–3 GB of free space during processing. After completion, the final file occupies the same space as the original video. UDL App does not require root access and works on both smartphones and tablets.
