This is a stable release as of 7/26/2020. The app has been in use for 3 years with all functionality performing as expected.
Recipes should be places on an accessible http (not https) server as txt files. Directories should be used to create categories. My use case is to run an apache2 on a server inside my LAN (not accessible from the internet). The app can be refreshed when on the same WiFi and will cache all recipes on a local database.
