Chrome -> Firefox

Gmail/Calendar/Drive -> Proton

Office -> LaTeX/LibreOffice

Maps -> Idk, not really many good options, apple maps is good too, but not sure if that’s what you’re looking for.

GPhotos->Immich Maps->OsmAnd~ from F-Droid if on Android and Magic Earth on iOS

I love the idea of osmand. But it’s not a substitute for maps at all ATM sadly. Im fair confident that if I tried to use it to navigate somewhere in my city I’d die.

I’ll check immich tho.
