nostr:npub1jv58d4ggwx7fjcsa9m8zvaxnrdf4ykk3k70q3lzxjz4ern4rl0hqzde22d A simpler one: an app that looks at location data of my photos library and lets me generate maps with “pins” of where I’ve been. Additional options would be ability to filter on years or countries, output very nice files back to my photo library. 

You could also use the location data for “achievements” etc.
