Intuitive GPS navigation using the topographic map of Belgium, Cartoweb from NGI

Makes from your iPhone/iPad a complete GPS device including a route planner based on the detailed Cartoweb topographic map from Belgium. The maps can be saved on your iPhone/iPad, so that Topo GPS can also be used without an internet connection.

Why should you buy an expensive GPS device if you can install Topo GPS on your device? Topo GPS contains all functions of a regular GPS device for less money, has a much more detailed map, and is more convenient to operate. The accuracy of the position determination is in favorable conditions about 5 m.

The price of the detailed map is 0.99 € for four sections of 3 by 3 km. For that you get lifetime access including future map updates. You can easily select the desired parts from an overhead view. For larger sections discounts will be applied. Purchases are made available on all devices that share the same iCloud account.

It is also possible to buy a one-year subscription which gives access to the complete map of Belgium.

Ideal for walking, hiking, cycling, mountainbiking, sailing, horse-riding, geocaching, scouting, trail running and other outdoor activities. Can also be used by outdoor professionals such as biologists.

If you are recording a route, the GPS will run in the background. Continued use of GPS running in the background can dramatically decrease battery life.

Rdzl, the company behind Topo GPS, does not obtain in any way the position of the user of Topo GPS. Rdzl does also not obtain the routes recorded by the user, and save the routes planned by the user, unless the route is shared with Topo GPS. We sell our product, not our user data.
