What if you could see the wind?

We're teaching a phone to read the wind right off the water — and we're looking for sailors to help build it.

The idea

Every gust, lull and shift leaves a mark on the water. Clip your phone to the rail, go sailing, and get a replay of the wind you actually sailed through.

We're early, and we need sailors to help build it.

You could…

The app is free — and the core always will be. Optional premium extras may come later; the wind replay stays free.
