## What is TideMeasure?

Measure sea-current speed and direction from your iPhone in minutes—built for sailors, coaches, and race teams. Map readings across the race area, review history, export CSV data, and share measurements with your team for smarter tactical decisions.

WHY TIDEMEASURE
Even a small current can change boat speed, laylines, mark roundings, and the favored side of the course. TideMeasure turns a simple drift test into a clear speed-and-direction result without specialized hardware.

HOW IT WORKS
1. Drop a floating stick or small object into the water.
2. Tap Start as it begins to drift.
3. Retrieve it after a short measurement.
4. Tap Stop to see current speed and direction.
