Re: What can't you do on Android WITHOUT a Google Account set up in the OS?

Android settings -> General -> Accounts

   And those accounts are only accounts on your *phone* (i.e. in
Settings) if the app so chooses. For example I have apps for several
airlines and for only one of them (KLM! :-)) the account shows up under
'Accounts and backup' in Settings.
   And BTW, Fitbit is *not* listed in my list of accounts (but as I said
before, I still have a legacy (non-Google) Fitbit account).

This thread has two separate components, to date:
 A. What Google apps cannot be replaced with private equivalents, and,  B. Which Google apps are the most dangerous in terms of privacy loss?
    (As those are the critical Google apps to define replacements for!)
For the latter question, and with the useful information provided by Theo,
we now collectively know of three Google apps which infest the Android
operating system with a system-wide integral account - which - wipes out
any chance of privacy (which means we need to find a FitBit replacement).
Google apps which automatically infest Android with a SETTINGS account:
 1. Google Gmail app (luckily which is easily replaced with a FOSS MUA)
 2. Google Voice app (probably which can be replaced by some other VOIP)
 3. Google FitBit app (maybe which may have an open source replacement)
So that we all learn from the dialogue, do you know of any others Frank?
