I used to add photos to Google Maps. As I grew up, I feel that I dont want to support us corporation.
Which alternative is the most popular in your country? In Poland I use mapy.com, and I add ratings, photos of the places. Is there any better platform? What do you use in France, Germany, Italy etc?
FOSS Android maps app where your contributions in the app also contribute to OpenStreetMap. https://f-droid.org/en/packages/app.comaps.fdroid/
Question however: Where is a good alternative to leave reviews for places?
You can leave reviews on MapComplete, it posts on MangroveReviews or Cartes which uses the blusky protocol.
