On life 360. if anyone in the circle pays, the upgrade seems to apply to the entire circle. One more recent member of our circle decided to pay, and we can see each others driving habit, and view some reports. But for most people, the free version should work just fine. Just be sure everyone you add to the circle is OK with sharing the info, but you can turn the tracking off from time to time, if you wish, it's easier for most people just to leave it on unless they really don't want anyone to know. You can also leave a circle completely or remove the app from your phone, of course. Also, the app will show not available or may show your last known location, if you are in a cell phone dead spot and are not connected to wifi. It will also show if someone's phone needs charging or is dead.
