I've always wanted a self-hosted tool to analyze my photos and turn them into maps. Then came my Croatian vacation, where the wind decided my hammock was its mortal enemy. At 2 AM, sleep-deprived and slightly windburnt, I retreated to the beach and coded the entire core of this app on my phone like a complete maniac.
It's still a beautiful disaster—powered by sea breeze, insomnia, and questionable life choices. But shockingly, most of it actually works.
All translations besides Bavarian (which I painstakingly did myself, because I'm apparently that specific flavor of weird) were churned out by AI, mostly EuroLLM and Claude. So if German reads like a robot having a stroke, you know why.
