A few other choices (links go to Hubitat integrations):
iOS/Android: OwnTracks - Hubitat integration by @brianwilson
iOS: Geofency - Hubitat integration by @brianwilson
iOS: Locative - Hubitat integration by @mikee385
Also want to mention that in addition to the built-in Life360 integration, there's an excellent integration from @bptworld.
