GeoTunnel

Ever wonder where you'd end up if you
dug straight through the Earth?
GeoTunnel finds out — instantly.

Snap a photo of the ground where you're
standing, and GeoTunnel uses your GPS
to calculate your exact antipode — the
point on the exact opposite side of
the Earth.

HOW IT WORKS
Drop a pin on the world map guessing
where you think you'll end up. Snap a
photo of the ground. GeoTunnel shows
you how far off your guess was!

DAILY CHALLENGE
Every day, everyone gets the same city.
You have 15 seconds to guess the
antipode — then compete on the
Global Leaderboard!

upvote the best holes, and compete on
the weekly Hole Feed leaderboard.
