Owntracks vs HA iOS App

Hi,

I’m a long time user of SmartThings, and I am experimenting HA right now. I actually have tried it a couple of years ago, but it was not too reliable. The first thing I noted is that HA has now an iOS App. How different is this app for location tracking compared to OwnTracks, which appears to be cited in every article about zone tracking, presence detection.

I have setup a few zones for iOs App, but I keep receiving “Significant Location Change Detected”, even when my phone is doing nothing on my side. Is Owntracks better in this regard? Could a VPN connection/disconnection trigger such events?

Thank you,
Rafael
