Kid3

Kid3 is an open-source audio tag editor for Android, listed in the Video & Media Players category. It is designed for people who need to maintain artist, album, year, genre, and other metadata in music files. The application can be used when tags need to be corrected, converted, or applied consistently across a collection.

For MP3 files, Kid3 edits ID3v1.1 tags and all ID3v2.3 and ID3v2.4 frames. It can convert tags between the ID3v1.1, ID3v2.3, and ID3v2.4 formats. Tag editing is also supported for Ogg/Vorbis, Opus, DSF, FLAC, MPC, APE, MP4/AAC, MP2, Speex, TrueAudio, WavPack, WMA, WAV, AIFF, and tracker module files.

The editor can change tags in multiple files at once, which is useful when several tracks share album information. It can create tags from filenames, create filenames from tag contents, and generate tags from the contents of existing tag fields. Kid3 also supports playlist file generation, automatic case conversion, string translation, and importing information from gnudb.org, TrackType.org, MusicBrainz, Discogs, and Amazon.

MirrorNest distributes the official Android build directly from its own storage and scans it for malware before publishing. This gives the download a clear place within the Android software catalog while retaining Kid3's open-source license and its focus on media file metadata. Its placement in Video & Media Players reflects its role as a tool for managing audio media rather than as a general-purpose file editor.
