Thanks, I did not come up with this idea.
Hi Filippo,
I have a free utility showing actual position of a Smarphone on another one. No costs by now, but now they are asking credit card
mad
so I'm not going to publish this App any more. It was a test around maps and Firebase messaging, to learn techs. But if you publish a final version different from alpha and beta, you cannot withdraw it, because the user are allowed to go on using it. At least I have a centralized DB which I can shut! Pay for something which doesn't give income...
Never beleave that something from those big companies is really free!
