Never miss your ship.
BackToShip uses offline GPS to track your walking time back to the pier — so you can explore every port with confidence.

The problem
Every year, thousands of cruise passengers are left behind at port.
Your phone's clock auto-adjusts to local time. The ship stays on ship time. That difference has stranded families in Cozumel, Roatan, and ports across the Caribbean.
BackToShip solves this with one simple number: how many minutes you need to walk back.
