MuPDF mini
APK
MuPDF Mini Viewer is a minimalist Android app that uses the MuPDF library to view PDF, XPS, CBZ, unprotected EPUB, and FB2 documents. This is a minimalist version of the MuPDF app, which focuses on reading only. It does not support editing annotations or filling out forms. The app will start with a file picker showing the contents of the external storage directory. Only files that it can open will be listed. Each document you open will start its own activity, so you can view many documents at once. Use the Overview system button to switch between the file picker and any open documents and other activities you have running. Tapping on the left and right side of the screen will flip to the previous and next pages. Tapping in the middle will bring up or hide the tool bars. A long tap will toggle highlighting of links. When the links are highlighted they are also active and tappable. You can pinch to zoom in. When zoomed in, tapping will scroll to advance the next screenful of content. In the toolbar there is a button to show the table of contents, if the document has one. In EPUB and FB2 documents, there is also a menu item to pick the font size. The scrubber at the bottom allows you to quickly jump to a given page in the document.

PS: *The name of the app is inspired from the main character of an anime called Ascendance of a Bookworm.* Note: The app also uses the Google Books API to fetch some extra data like book summary and pages count etc, as the GutenBerg project don't include those values in their metadata. It tries it's best to map the data received from Google books with Gutenberg's metadata but the mapping is not 100% accurate and not all books available on GutenBerg is also available on Google books or is available but with different title, so you may find some books without summary or page count etc.

NATINFo+
APK
NATINFo+ is an example of a client application that can be used to search for and consult offences in the NATINF nomenclature via the NATINFo API (https://codeberg.org/retiolus/natinfo). What does ‘NATINF’ mean? ‘NATINF is the nomenclature of French offences (NATure d'INFraction). This nomenclature is defined by the French Ministry of Justice. It is used by all legal services and government departments, in particular to record proceedings, monitor statistics, etc.’ - justice.gouv.fr Features The application lets you search for an offence by NATINF number, title, article of law, code, etc., and consult all the information using the NATINFo API. Its main advantage over the natinfo.app site is that it downloads all the available data on the first launch and stores it locally. This means you can consult it offline - with the added bonus of faster display times. The data is then updated automatically with each search when the connection is active. The app is also customisable: light or dark theme, badge colour (fince/offence/crime), it provides a history of NATINF consultations and favourites management for quicker retrieval, and offers practical tools for calculating blood alcohol content, speed and locating road points.
