Step inside the story

Walk with the people who were there.

EraHopper transforms your phone into an immersive portal to the city's past. Stand at the coordinates, and a real historical figure takes over your headphones—speaking directly from their own era. You don't just listen; you decode architectural clues, unearth forgotten artifacts in the public realm, and discover the hidden stories baked into the modern grid. No app store downloads required.

How it works →

"Makes me feel like I have a secret about the city."

An experience unlike any walking tour you've taken.

Step 01

Meet your historical guide.

Head to the first stop. There, you'll meet a real historical figure who shaped streets where you're standing, brought to life through rich, immersive audio drama.

Step 02

Step into their timeline.

As you reach each location, the next chapter unlocks. No modern tour guides or textbook history lessons here — only first-hand accounts from characters speaking directly from their own era.

Step 03

Unlock the streets around you.

The physical environment is your game board. Use archival photos, match real-world objects, and hunt for hidden architectural clues to progress through the narrative. If you pay close attention, you'll discover secrets hiding in plain sight.

Choose your quest.

Golden Gate Park
A Garden at the Edge of the World
A naturalist who shaped the park from the ground up

Walk through one of the most improbable parks ever built — coaxed out of barren sand dunes and ocean fog. Your guide knew every plant by name, and he spent fifty years fighting to keep his wilderness entirely untamed. Match real-world plants to original drawings, hunt down the "stone men" he tried to bury in hedges, and discover the secrets of a master gardener.
