It's exactly the same. Until recently, Chipolo one was the only option for Android users, but it is now less useful.

But I'm also not sure whether the Chipolo is even shared via a network of devices/apps without it, or only via your own.

The Find my Service network from Google/Android is currently not yet very sophisticated and is actually only successful in heavily frequented places such as swimming pools, railway stations, etc. Even when travelling through Zurich by public transport, it is hardly recognised anywhere.

This is either due to Google's default settings or because not so many devices have yet activated and set up the function.
