Fixed in https://github.com/badbundle/vault-app/pull/671 (merged as 7c588ec).
The About page has a More Apps section between the policies and the footnote, with rows for Track Slash, GPS and Split Thing from bad-bundle-apps 0.1.0 (pinned exact). Bradley confirmed About rather than Settings.
Split Thing's badbundle.com page is still in bad-bundle-web #30, so its row opens a missing page until that merges.
