Build the best cross-city smart participation app

The CitySDK project was set to harmonize APIs across several cities in Europe. Helsinki, together with Amsterdam, Lisbon, Lamia and Rome, implemented an issue reporting API. The API is also compliant with the Open311 interface, which is used in several cities in the USA and elsewhere.

'Helsinki loves developers' has launched a CitySDK challenge in which they seek the best cross-city smart participation app. They are looking for handy mobile apps, visual city dashboards and innovative digital solutions. Get inspired by other applications: take a look at Open311 Dashboard, Street Bump app, Chicago's issue reporting app or Korjaa kaupunki.

5,000 euros prize money
The winning app or service will receive 3,000 euros and the second prize winner 2,000 euros. All apps will receive EU-wide attention in the CitySDK partnered cities.
