LaTeX packages that get shipped with Texpad iOS form a subset of the full LaTeX distribution that is a large and monolithic. It is designed that way so as to cater a broad range of typesetting needs. Not only would it be unnecessary to pre-install all these packages in Texpad iOS, it would also result in a very large app, taking up up to half a gigabyte of space on your device. Texpad's Bundle Manager helps distribute these additional packages as they are needed. It may be accessed from the Settings' pane:

## Uninstalling bundles
