• Radio Stations: https://opml.radiotime.com/
• Country list + phone codes: https://restcountries.com/

Bottlenecks:

• Server not the best. Requires some core workarounds, which impact the whole app.
• As an example:
  • single, all-on-one CategoryEntity for categories and everything. Ideally should be separate.
  • position field for saving in DB. There is a predefined sort from server but no query/response param for that.
