Walk Through Time. See Cities Rise and Fall.
AR livestream walking tours where history comes alive. Watch streets transform from 1920 to 2025 as you walk. See vanished buildings rise like mirages. Our ant-colony sensor network crowdsources data from thousands of walkers to build continuously updating 3D historical maps of urban spaces.
You're virtually strolling down a NYC street in the app, and suddenly the 2025 buildings dissolve like mist, revealing the same block in 1900 - horse-drawn carriages, tenements, all perfectly aligned to your walking pace. Then tap any building and watch it transform through 5 decades like a timelapse, all synced to your movement.
