It's good that someone has made that but it looks nowhere near as nice.

When you open the Photos app on iOS you have a beautiful map with clustered thumbnails.

It's useful enough that I could find out the exact spot I slept by the river Seine years ago based on scrolling around Berlin on the map for 5 minutes until I found the photo, taken several years ago on a completely different iPhone, then go back there recently and recreate the picture.

FWIW samsung's gallery does that https://imgur.com/a/Qgc3yUH (probably only on the S8 and above but idk )
