contagt – Maps, Guides & Nav

contagt guides you in buildings and locations all over the world. Thanks to innovative technology, you will be automatically informed about the availability of a guide.

Indoor navigation made easy! Are you looking for a specific office space? You want to find the closest bathroom? Or you are not sure where you parked your car? With contagt these questions are a thing of the past!
contagt is the easiest app for orientation in smart buildings and on sites. And this is how it works:

- LOAD GUIDE: Choose the guide you want and download it.
- SELECT DESTINATION: Find your destination directly via map, directory or text search.
- NAVIGATION: Be guided on the optimal route to your destination.
- SHARE: Use the share button to meet up more easily.
- DISCOVER: Many guides offer even more information, features and services!

The app only works at locations for which a contagt guide has been created. Some guides are only available with a password or directly at the location.

- QR/NFC scanner: Scans QR codes and NFC tags to determine your current location (NFC must be activated in the smartphone settings).
- 3D map: Movable, zoomable, rotatable, and clickable venue map based on OpenStreetMap (OSM). After downloading, map data is available offline.
- Routing: Calculates routes from any location at the venue to any destination and visualizes the routes on the map, including route options.
- Navigation: In buildings that are equipped with Bluetooth beacons, smartphones can determine their location indoors and provide live indoor navigation.
- And much more: Using the share button you can share your location with your friends. In addition, many guides have further functions that you can access via the side menu and/or the map view.

- (GPS) location: As a source for positioning outside buildings
- Photos/media/files: To be able to save guides on the SD card
- Camera/near field communication: To be able to read QR and NFC tags
- Bluetooth/WLAN connectivity: As position sources for indoor navigation

Privacy is very important to us. We guarantee that no personal data will be collected or transferred to us or knowingly to third parties. The permissions requested by the app are necessary to enable navigation and are used exclusively for this purpose. Location services can be disabled at any time.

We are continuously developing our app and integrating new features. For questions, ideas and comments we are of course always available. Just send us an email to We are looking forward to your message!

Please note: Continued use of GPS running in the background can dramatically decrease battery life.

contagt is optimized to consume as little power as possible during navigation and reduces the load for the wireless connections to a minimum.
