Logging in is annoying.
I understand the purpose of logging in to an application. Afterall, users are the product you sell to advertisers, right? However, it's such a pain. The app logs me out constantly and I can never get back in with the same account, even if I use the Facebook or Google integration. I have like five different Waze account that I can't use because the accounts that are integrated from other services aren't accepted anymore.
It's a major hassle. Google Maps doesn't make you log in. Apple maps doesn't make you log in. And Waze doesn't MAKE you log in either, but it hassles you and annoys you if you don't. And even if you do log in, it's still extraordinarily annoying with the candy and stupid stuff I don't care about.
