In the Wiki “Known Repositories” (Known Repositories) other Repositories are suggested, which offer alternative apps to Google ones and - as I understand - similar to F-Droid.
But I do not know and did not understand, how can I integrate (or add ?) these under the F-Droid app.
Hi Licaon_Kter, your suggestion seems logical, I do similar on my PC, but in my Smartphone (which one? see above) I cannot find a Repo-Setting (or similar).
