@hehemrin I think the requirement of privacy is incompatible with iOS. Apple will track you anyway.
Also, FOSS becomes less meaningful because with iOS you cannot really know what you install, you cannot build and install from source and you cannot know if Apple have modified the app you install. The program you actually install may not correspond to the public source code, you will never know.
You need to move from iOS to a free (as in freedom) operating system! Then install a FOSS pod app 🙂
@eliasr And I would not mind a phone like Librem5 or PinePhone. But unless dual boot, I do not believe I manage to get them work with the example apps. Or if if I install LineageOS, PostmarketOS, or the other OS I am aware of, on an Android phone. Tell me any suggestion you know.
@eliasr I can sympathize with your suggestion. It has occurred to me too. It will not happen soon for me, but anyway: which OS do you suggest and why, for a free phone? Regarding mobile in general, I use it for as little as possible, not only for privacy. I prefer computer with big screen, keyboard and mouse. So very few apps on mobile.
