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.
