OffMaps²

OffMaps² provides offline maps for thousands of destinations around the world. It is a perfect showcase not only for our custom map rendering engine QuartzMaps, but also for our passion and talent on the iOS platform.

OffMaps² is the successor to the wildly popular first version. It is one of the pioneers of a new generation of travel guides based on open data and designed for a mobile experience from the ground up.

We prepare maps and Wikipedia companions for thousands of regions and cities in over 150 countries around the world. We also provide recommended walking tours for major destinations.
