# SongTube App review: Flutter downloads and playback > SongTube is a Flutter application for downloading, converting, playing, and organizing YouTube media. It suits users who want separate audio and video storage, but its README documents distribution links rather than build commands. **SongTube/SongTube-App** — Simple & Beautiful App (Tool) made in Flutter to Download Media from YouTube - Repository: https://github.com/SongTube/SongTube-App - Website: https://t.me/songtubechannel - Stars: 1,393 · Forks: 162 - Language: Dart - License: GPL-3.0 - Published: 2026-10-16 · Updated: 2026-10-16 · Language: en - Canonical page: https://hysenlabs.com/projects/songtube-songtube-app ## SongTube's purpose for media library users SongTube addresses the gap between watching YouTube content and maintaining a local media library. The repository describes it as a Flutter application for downloading media from YouTube, with particular emphasis on music. Its listed functions include audio and video downloads, music and video players, playlists, watch history, favorites, channel subscriptions, search filters, and external sharing into the application. The likely audience includes listeners who want to save audio for local playback and viewers who also want downloaded video. SongTube goes further than a basic download interface by including audio tag and artwork editing, conversion to AAC, OGG, and MP3, volume and equalizer controls, and separate download paths for audio and video. Local playlists and backup or restore of application data are also documented. Based on the repository layout, SongTube is a cross-platform client rather than a server-side download service or a reusable developer library. The shared Dart codebase lives under `lib/`, while native project directories exist for Android, iOS, Linux, macOS, Windows, and web. The `assets/` directory likely contains packaged resources, and `pubspec.yaml` serves as the Flutter project manifest. The README does not explain the download parser, request flow, caching system, or platform service integrations. SongTube should therefore be evaluated as a consumer application with a broad media-management interface. Its feature list indicates intended capabilities, but it does not establish that every download, conversion, or playback feature behaves identically on all six platform families. ## SongTube's audio, video, and library data flow The documented workflow begins with a user viewing or locating a YouTube video inside SongTube or receiving one through an external sharing action. The user can then save it under the configured video or audio path. SongTube treats these as separate destinations, which is useful for users who organize music separately from watched or saved video. Audio processing includes conversion among AAC, OGG, and MP3. The README also lists volume, bass gain, and treble gain as audio download features. Video downloads are described as supporting up to full quality. These statements describe the intended options, but the README does not list source codecs, output bitrates, container formats, sample rates, maximum file sizes, or what happens when YouTube does not expose a requested format. The playback side includes a full music player, a full video player, a music equalizer, Picture-in-Picture, and background playback. Background playback is explicitly described as being at the Alpha stage. That designation indicates a feature whose behavior should be checked against the target platform rather than assumed to be complete. Watch history can be paused in settings, while favorites and playlists provide local organization. SongTube also supports audio tags and artwork editing, UI customizations, and separate system, light, and dark themes. A backup and restore operation covers local application data according to the feature list. The README does not document the backup format, restore conflict rules, encryption, or whether backup covers downloaded media as well as metadata. Code inspection or product documentation would be needed before treating backup as a complete media-library migration system. ## SongTube installation and first media download The README does not give package-manager commands, a Flutter SDK setup, a `flutter build` invocation, store listings, or dependency versions. It says to obtain SongTube from the official Telegram channel and also lists a GitHub download location. The following block contains those documented destinations, not executable installation commands: ```bash # Official SongTube Channel: https://t.me/songtubechannel # Other SongTube download location: https://tinyurl.com/STGithub ``` The official Telegram channel is also the documented route to the project's support group. The README says users can submit issue reports and recommendations there. It does not identify an app store, a signed package name, platform prerequisites, supported device versions, or checksums. For a first real use, obtain the build for the intended platform, install and open it, locate a YouTube video, and invoke its download function. The result should follow the audio or video download path selected in settings. The README does not document exact menu labels, dialog fields, or progress messages, so the interface sequence cannot be reproduced reliably without guessing. Users who receive media through an external app's sharing system can use the documented integration. SongTube Link users can start from a desktop Chromium browser instead. Those entry points avoid requiring the video to be rediscovered through SongTube's internal search, but exact integration setup is covered separately for the extension. ## SongTube Link and Chromium desktop handoff SongTube Link is a separate Chromium extension that sends videos to SongTube. According to the README, it can pass a video for watching or immediately download it as music. The selected output is controlled by the application's instant download format setting, which means the browser extension delegates the final format decision to SongTube. Automatic device detection requires the SongTube desktop application. If detection fails, the README says the user can manually enter the device IP Address. This implies communication between the browser extension and the desktop client, but the SongTube App README does not identify the transport, connection port, firewall requirements, discovery protocol, or security controls. A deployment that depends on manual IP entry therefore needs testing on the intended network. The extension has its own repository, `songtube_link_extension`. Features such as supported Chromium versions, extension permissions, and extension update procedures should be checked there rather than inferred from the mobile and desktop application. The division is operationally significant because the browser handoff can fail even when downloads initiated inside SongTube work normally. ## SongTube format, platform, and feature boundaries SongTube's central limitation is the gap between an extensive advertised feature set and limited implementation documentation. The README states that video and audio downloads support up to full quality, but it does not explain whether every YouTube video has a downloadable audio stream, whether age-gated content is supported, or how authentication requirements are handled. It also does not define whether downloading depends on a signed-in YouTube session or an external service. Format support is similarly bounded. AAC, OGG, and MP3 are listed as conversion outputs, but source compatibility and transcoding quality are not described. The README does not state whether a conversion changes the original stream, whether metadata survives conversion, or what CPU and storage requirements apply. Users who require archival bit-for-bit output should not infer that behavior from the conversion options. Cross-platform support is visible in the repository directories, but feature parity is not documented. Picture-in-Picture, background playback, equalization, custom paths, and external sharing may depend on the target operating system's APIs and permissions. The web directory exists, yet the README does not identify which download or equalizer features are available in a browser context. Background playback has the clearest maturity warning because the README labels its implementation as Alpha stage. The documentation does not identify affected platforms or known failures. File naming, download collisions, queue behavior, resume support, storage checks, and partial-download cleanup are also undocumented. These omissions do not prove that the features are absent, but they prevent a production-readiness claim based on the README alone. ## SongTube releases, maintenance, and upgrade work The repository is not archived, and the last push was on 2026-08-01. That date corresponds to release `7.4.0+6000`. Earlier listed releases include `7.3.2+5200` on 2024-03-26 and `7.3.1+5100` on 2024-03-22. The gap means the repository should not be described as receiving regular releases throughout that period, even though the latest listed release is recent. The README does not describe an app-store update channel. If SongTube is distributed through downloadable builds, adopting a new release may involve obtaining and installing the binary manually. The repository contains a `CHANGELOG.md`, but the README does not summarize migration requirements or breaking changes for `7.4.0+6000`. Engineers should inspect that file and the release artifacts before upgrading a managed deployment. Local data increases the upgrade surface. Playlists, history, favorites, tags, settings, and downloaded files are separate concerns. SongTube documents backup and restore, but it does not state whether metadata backups are forward-compatible across releases or whether restore replaces existing data. Teams using SongTube as part of a managed media workflow would need to preserve their own copies of the documented backup artifact. This maintenance picture is acceptable for a consumer application that is actively receiving occasional releases. It requires more checking before an organization treats upgrades and local libraries as routine, repeatable operations. ## SongTube GPL-3.0 distribution considerations SongTube is licensed under `GPL-3.0`. Engineers who modify, redistribute, or distribute covered binaries should review the license text and determine how its requirements apply to their specific distribution method. This is a technical licensing consideration rather than legal advice. The repository also contains `pubspec.lock`, which records resolved Dart dependencies, and platform directories that may include their own libraries and assets. The README does not provide a third-party license inventory. Any compliance review therefore needs to cover the GPL-3.0 project license, Dart packages declared in `pubspec.yaml`, native dependencies, and any bundled media or fonts under `assets/`. SongTube may be a poor fit for organizations that need a permissively licensed application to modify and embed under restrictive product terms. It may be suitable for personal use or deployments where the distribution model is compatible with GPL-3.0 after a separate license review. The project does not document exceptions or an alternative commercial license in the README. ## Conclusion SongTube fits users who want a music-centered YouTube client with audio and video conversion, custom storage paths, playlists, tagging, local playback, and backup. It does not fit developers who require documented command-line installation or users who need explicit guarantees about YouTube format availability. Before adopting it, check the official download source, platform compatibility, backup file format, behavior of Alpha-stage background playback, and the media formats needed by your workflow. ## FAQ ### Where can I download SongTube?
