Od Bałtyku po Kaszuby is a tourist guide application that provides information about more than 100 hiking trails in the Pomerania and West Pomerania provinces. The app was created by a partnership project between Forest Districts and Municipalities of several cities. The app allows users to browse tourist routes on a map, including hiking, biking, kayaking, skiing, horse riding, and Nordic Walking. Each route is accompanied by interesting objects, including places for sightseeing, nature, catering, accommodation, and other tourist attractions. The app also provides an elevation profile for each route. The built-in GPS technology allows users to sort and locate routes and objects by their proximity. Moreover, the app has a built-in navigation system that guides users along the route or indicates access to the beginning of the route or individual objects. The app's navigation system also informs users when they step off the route. The app has a database of over a thousand objects that are divided into categories, and each category has its business card, which contains a description, contact details, and location. With this application, users can learn about the most important events in the area. The app uses GPS technology and works offline.
