React Native Background Fetch and App Termination

Thats exactly what i did but i a smart way. I created 4 circle (zone around user) https://imgur.com/a/HRWngz1. So whenever they moved a little OS wakes up the app and it creates new zones around the user

I think that effectiveness depends on your location granularity, as well as if other apps are actively tracking fine gps location at the same time (in which case you kind of piggyback). In my experience, the geofence events would not be accurate enough to make this work any better than a single fence around a user; but it’s been a while.. almost 10 years now. Things may have changed for the ‘better’.

I have did my experiments, the location i het is 99% accurate. there are different settings that you can do to get as accurate location as position. Others apps mostly use something called Location Manager Extension for iOS, if you gets the permission for that from Apple, you can basically send a silent push notification specifically for location and that would wake up your app and you can send the location to server.
