App to manage a second google account without mixups

[Samantha Tharpe]

Like basically to replace guest mode since my phone doesnt have that option.
I dont want my activity from both accounts getting mixed up but i want both of them to sync on other devices if that makes semse.

It sounds like you want two phones on one device... without a separate user account.

While that has been done in the past (I used Bootstrap on the Note 4 to select various ROMs installed, each with its own account and home screen), I believe that would be impossible now. Google's account signatures are designed to prevent theft or fraud: only ONE primary account can be on the device. Even user accounts are, as you said, guest accounts. If the device is stolen, not even a factory reset can wipe the primary account credentials, which will be required for any further login.

I know you don't like the answer I have for you, but it's the one I have.
