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.

Nextcloud Cookbook
APK
This app is a viewer for recipes in Nextcloud App. The synchronisation can be done direct (with nextloud) or with the local storage. Synchronize directly works with Single Sign On (SSO) per nextcloud client. The local storage can synchronized in other ways, there is no dependency to a client. First steps After first installation (or with the current update from 2.x.x to 3.0.0) it shows the login screen. If the nextcloud client is installed and you want to synchronize direct with the nextcloud server, you can use the login button to show a list of accounts and you choose the account to login. Then the app will download the recipes with the REST api. If you want to synchronize with the local storage, you can skip the login ("Skip for local storage"). After that, you have to choose the recipe directory in the settings and permit access. In the app "All categories" is the main view, there the app is loading the recipes from the choosen directory. When using the Nextcloud Android client, you find the directory on your storage under Android/media/com.nextcloud .client/nextcloud/<your account>/<folder>. You also can choose the theme in the settings. After that, the start view has a list of recipes and you select a recipe to view the details. IMPORTANT: With direct pick of the nextcloud folder there will no images shown and the uri can't be stored right. Perhaps at next app start no recipes can be loaded. Therefore it is better to use the above mentioned path on the SD card (see First steps).
