There is now an app called „Tracker Detect“ from Apple (for Android) to search for AirTags around you. It hasn’t the ability to use AirTags like on the iPhone but at least you can find one that has been left around you.

That app, which isn't available everywhere (why?), requires users to perform manual scans. It doesn't warn users that they're being tracked like iPhones do.
