I built GeoEchoes because I wanted a way to leave and explore discover real-world memories that don't vanish—audio, video, or text tied to specific locations, stored permanently on Arweave.
The app lets you unfog the world in grids (using H3 hexagons for spatial indexing and analytics, e.g., "25% of Brooklyn discovered").
A radar helps pinpoint nearby echoes. You can create your own at any spot, or find ones left by others.There's also a boundary creator tool for drawing custom zones (boundaries.geoechoes.com), randomized loot collection (like series clips or history facts), and clubs for challenges/private echoes.
Soon adding user-created animated characters.It's live on Android, iOS, and web
Feedback welcome of course. What do you think of the Arweave/H3 integration or the overall idea?
Inspiration kinda Daniel Johnston "The sun don't shine in your tv"
