It could be replaced with a fucking web app if they built it properly the first time around.

Do you know a good way to do geofencing on PWAs? I'm not saying you can't, but I don't know of any API that can accomplish that (without constantly running GPS location updates in the browser, which no standard phone will allow).

I'm unfamiliar with these apps. What is geofencing used for? Automatically alert you if there is ICE activity nearby so that you can drop what you're doing to converge ?

There's an alerting feature and an attempt to stop false reports. The map part is trivial (and I think someone is already scraping the locations into a web app), but the geofencing capabilities are more difficult.

I believe it serves two purposes:

1. Reduce false reports by ensuring that activity reports are reasonably geographically near the reporter's location

2. Send alerts to people who are near a cluster of reports.

Maybe have the app server contact a service that knows the user's location? You can probably somehow get the user's location on Google Maps, or Find My. Or... I don't know, Yelp check-ins with a particular hashtag?...
