I hope that my list of apps will help out people, particularly those new to this world of privacy. These apps fit into the categories that people typically look for or should have and they are all at least fairly recently updated.
Notes
- Required repositories for these apps: F-Droid, DivestOS Official, Guardian Project Official Releases, IzzyOnDroid, Fedilab Apps, FUTO, Molly F-Droid Repo, NewPipe upstream (preferred)
- Simple Mobile Tools has been sold to ZipoApps and thus not worth downloading anymore. FossifyOrg is the “official” fork now and will be releasing their versions soon
deGoogled Android Operating Systems
- GrapheneOS (highly secure OS with sandboxed GooglePlay as an option)
- CalyxOS (uses MicroG)
- DivestOS (hardened fork of Lineage with ability to re-lock bootloader)
- LineageOS (many phones supported)
- /e/OS
