Side Project Spatial Memory: Lessons from 3 Weeks of User Testing

Developer Kevin Ten launched Spatial Memory, a location-based app for pinning digital memories to GPS coordinates, and got 8 out of 20 testers to actively use it. The app runs on Go, PostgreSQL, PostGIS, Redis GEO, and Cloudflare R2 at zero hosting cost. Key learnings include strong privacy design and the emotional reward of seeing users connect through the app.
