Tunetag MP3 Tag Editor 4+

Edit your MP3 files' tags easily with Tunetag.

- File Management
Tunetag supports file management directly from the built-in iOS/iPadOS Files app, so you never have to fumble with share sheets or AirDrop. 
Move your downloaded MP3 files directly to the Tunetag folder in the 'On My iPhone/On My iPad' folder, and Tunetag will automatically pick them up.
If you're not sure where to go, simply tap the 'Open Files App' button in-app.

- Tag Editor
Tunetag supports editing the following fields in MP3 files: Title, Artist, Album, Album Artist, Year, Track Number, Genre, Composer, Disc Number.
You can also select an album art to attach to your MP3 files.
Additionally, you can use replacement tokens that use information from a file's file name to fill out tag data.

- Batch Editor
You can easily edit multiple files at one go, changing only the fields you want to change.
The same replacement tokens you can use in the Tag Editor can also be used here.
Have many files? Either drag and drop them to the drop zone in the file browser to add them to the Batch Editor, or long press a folder to add files recursively. 
You can also drag files from the Files app directly into the Batch Editor.

Note: Editing many files at once, or using large album art images may result in longer save times.
