@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 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.
@hehemrin one way to handle all this is to have two phones, one with a free OS which you strive to use for everything you can and use more and more, and another one that is only for the few things that you think only work for Apple/Google. Turn that off most of the time and only pick it out when you really have to, and strive to use it as seldom as possible. Always ask for ways to use your free phone instead, so that you contribute to the growth and demand for free alternatives.
