Android App for tagging locations on a map?

I'm searching an android app to mark the locations of multiple parked cars. It should be possible to mark different cars somehow to identify them. It would also be cool if there is a feature to share the location with someone on another devica (like a sync between users, NOT copy of coordinates or link on maps

In other words, I need an app to tag multiple locations on a map. It doesn't require to be designed for parked car locations. The app must have these features:

• GPS Tracker with map
• support to tag multiple locations
  • mark them somehow uniquely (like note, category, color, icon, ...) The following features would be nice to have:
• sync with other devices, for example family
• history of locations
• set date/time since location is active (can be timestamp)

I'm ok with paying/ ads or require to self host.
