This is an app which can load GLS packs (another tool i've been working on to split Glossika GMS/PDF files into individual sentenceGroups) and use the old Glossika mp3 + PDF courses similar to the new AI platform.
Eventually, it will support other courses (including user/community-created courses) as well.
There are a couple videos on youtube showcasing some of the basic features, such as loading a language and creating a course.
