Actual alternative to Google Maps?

I have noticed that many people have given alternatives to Google Maps. That being said, I wonder if you know a service that has both a mobile and a desktop version. So far I've seen options with only a mobile app or a desktop app, but not a service that combines both. I want to have that so that I can save places while using either and that it'd be reflected in both maps. I don't mind creating an account, but I'd like to have collection lists that I can use interchangeably.

Thanks in advance.
