NaviTasks

The app was created for learning navigation and solving problems based on the Polish School of Navigation. Before purchasing a subscription, gather the necessary materials: a navigation triangle, a compass, a pencil and a notebook or sheet of paper, a ruler or a second navigation triangle, and the materials from the "Printable Materials" tab. Learning – this is not a navigation textbook; therefore, this mode contains only concise information related to marine navigation. It includes calculation examples and graphics explaining chart work and operations in tidal waters: measuring distances, plotting ship positions, drawing courses and bearings (simultaneous and non-simultaneous pairs), calculating horizontal angles (sextant) and vertical angles (sextant), plotting courses in tidal waters, working with tidal curves, and calculating tides for secondary ports. Tasks – a collection of navigational problems: fixing positions and point-to-point navigation, simultaneous bearings, non-simultaneous bearings, distance and bearing, distance (horizontal angle) and bearing, navigation in tidal waters, calculating required water levels, and calculations for secondary ports. Total number of exercises:

• 12 exercises involving magnetic variation (declination) calculations
• 32 exercises for A4 charts
• 32 exercises for A3 charts
• 16 exercises for tidal water calculations
• The entire app contains 86 paid exercises—approximately 3 exercises per day with a monthly subscription. Free exercises – a set of 6 navigational tasks. The Premium version grants access to the "Learning" section and all navigational exercises. The Basic version grants access to all navigational exercises. In addition, the application includes materials that must be downloaded and printed: an A4 map, an A3 map, tidal curves, secondary ports, and a plotting sheet for secondary ports.
