Kommunekart, developed by NORKART AS, is a free Android application that provides users with detailed maps and aerial photography for all of Norway. The app allows you to search for addresses, places, and properties across the country and get turn-by-turn instructions for getting there. Additionally, if you live in one of the forward-looking municipalities, you can get access to extra detailed maps for your municipality, including zoning plans, property information, and approved construction information.

The app is user-friendly and easy to navigate, making it a great tool for anyone looking to explore Norway. It is worth noting that continued use of GPS running in the background can significantly decrease battery life, but you can turn off GPS at any time using the app's settings. Overall, Kommunekart is an excellent app for anyone looking for free, detailed maps and aerial photography of Norway.
