Project Details:
The CityServer App, developed for the Posmo Cooperative Switzerland, is an innovative solution for cities and municipalities to analyze the condition of their bicycle paths and uncover potential for improvement. As a freelance iOS developer, I co-developed this user-friendly and powerful app for the Posmo Cooperative Switzerland.

The app allows users to cycle along predetermined routes, automatically taking a photo every 10 meters. The GPS coordinates are inserted into the EXIF data of the images to later enable precise localization on the map. After completing the ride, users can upload the images directly in the app.

Participating cities gain access to a detailed map with all the rides and can view the images to assess the condition of the bicycle paths. This enables the city to make informed decisions about which paths need to be expanded or maintained.

The CityServer App is a prime example of the efficient combination of modern technology and practical application that helps cities and municipalities improve their infrastructure sustainably and meet the needs of their citizens.
