This is a bit old thread, but I've found this app while searching for alternatives to Google Maps app, and I would like to know others' thoughts about it.
It seems that the Gmaps WV was originally made by DivestOS (disappeared) and that a developer called woheller69 is maintaining it right now.
The app is in F-droid: https://f-droid.org/en/packages/us.spotco.maps/
Firstly, didn't trust this app much, but I saw that the maintainer is the developer of SherpaTTS, which I already have installed in my phone, so I decided to give it a try.
My main use case is to search in Google Maps for what I cannot find anywhere else (places, photos, reviews....). I tried to do that using google.com/maps in the browser, but that's very annoying, because the Google Maps web version for mobile is constantly pushing you to download the Google Maps app.
Gmaps WV solves this problem, providing the decent user experience of Google Maps web, without annoying messages. So, it looks like a good solution for me, but I don't understand how is that actually done, and how safe is to use this app... Any idea?
