What Tonnr does
Your spots, your conditions
A spot is a point on the map and the conditions you trust: swell height, period and direction, wind, and tide. Keep it private, make it public, or share it with chosen people.
An alert on a match
Tonnr checks every spot against live measurements and forecasts, and lists the windows when it should work.
Measured at sea
Wave buoys and wind stations from public networks, read continuously, each with its source and its license.
Open by design
The data behind the app is a public API. The code is open source under the AGPL, and you can host your own instance.
