## What is True Wind Pro?

True Wind Pro is a precise nautical wind calculator and training tool designed for sailors, navigators, and marine students.

Convert apparent wind into true wind direction and speed using the classic nautical-school vector method — clearly visualized and easy to understand.

Key Features

• True wind direction (TWD) and speed (TWS) calculation
• Apparent wind (AWA / AWS) support
• Atmospheric pressure readings using the iPhone’s built-in barometer sensor
• Pressure history with date and time
• Easy access to pressure, wind direction, and wind force values for entering into the ship’s deck logbook on the bridge
• Interactive radar and wind triangle plot
• Step-by-step vector construction (nautical-school method)
• Reverse calculator: find heading for a target apparent wind angle
• Beaufort scale interpretation
• Clean, distraction-free interface optimized for marine use

Designed for Learning & Practice

True Wind Pro doesn’t just give you numbers — it shows how the result is constructed. Perfect for sailing schools, exam preparation, and real-world navigation planning.

The app also helps with practical bridge routines by making atmospheric pressure, wind direction, and wind force easy to check and enter into the ship’s deck logbook.
