BusNavi is a free public transport application developed by Mobicore that provides users with an efficient way to navigate public transit systems. The app offers a range of features that include checking timetables online and offline, an online and offline trip planner, and a map that can also be used both online and offline. BusNavi's offline capabilities make it a reliable companion for commuters, as it doesn't require an internet connection to function.

In the United Kingdom, it supports London, while in Poland, it supports over 40 cities, including Krakow, Warsaw, and Wroclaw. The app also offers widgets that allow users to access important information directly from their home screen. With BusNavi, navigating public transit has never been easier.
