I'm torn on this for any app-operating companies/orgs based in the US.
The real-time maps mean at best they're able to see at least the IPs of users, and at worst, a ton of device or personal information (depending on what perms are granted to the apps). This would be a treasure-trove of info for ICE. A lot of women stopped using period-tracker apps for a reason after Roe was overturned.
Also, unless people are side-loading the apps, Google or Apple will also know exactly who downloaded them, since you can't download through their app stores anonymously.
There are websites with real-time information that don't force you to install an app to view, and visiting a website rather than using an app makes it much easier to minimize the information you're leaking.
I'm glad that some of these apps are shutting down preemptively if they are certain they don't possess the resources, or are located in a safe enough place, to ensure their users' privacy. Ideally they would partner with a legal entity outside the US to operate the app instead, but obviously that's a big burden.
