I liked Google Maps on my iPhone right up until they started nagging me to sign in before I could get directions. The minute I saw that screen, the app was gone.
It's possible I misread the screen that popped up when I tried to search that said something along the lines of "Choose an account to sign in" instead of showing me the map I asked for, but if you're looking for product feedback: whatever screen it was, it was enough to get me to stop using the app.
For a long long time that particular screen had no history whatsoever if you weren't signed in, but that's been fixed for a while now as well.
