Panorama Tatr is a free Android application developed by Jacek Fedorynski and is designed for travel and navigation purposes. The app uses sensors on your phone, including a compass, to overlay labels on the camera image of the Tatra mountains visible on your phone screen. The labels correspond to the visible peaks in the Tatra mountains.

The app is straightforward to use, and if the peaks shown by the app do not match those in reality, you can calibrate the compass by moving the phone in a figure-eight motion. If this does not fix the problem, you can adjust the peaks' position manually by dragging them on the screen until they match what you see in front of you.

Overall, Panorama Tatr is an excellent app for those who love to hike or explore the Tatra mountains. It is easy to use and provides an additional layer of information that can help you navigate the trails.
